Managing The Human Side Of Smart Manufacturing
Change management is just as important as new technology in a successful implementation.
People have the power
The core belief that drives the work we do here at Flexciton is that, for the semiconductor industry to advance to the next level of efficiency, it has to comprehensively embrace smart manufacturing practices.
As I’ve written previously, the rollout of smart manufacturing will require fabs to adopt ‘disruptive’ cloud-based, AI-driven technologies. As such, the move to smart manufacturing will be an absolute step change for most companies and will result in some fundamental adjustments to the way that the fab works. Yet ensuring that these new technologies integrate seamlessly with the existing systems is only part of the challenge.
Ultimately, the success of a smart manufacturing implementation will be decided by the people who work in the fab. For these new technologies to deliver the efficiencies they promise, there has to be total buy-in from the staff who are expected to work with them, particularly in legacy fabs where final decisions are still often made by humans. This is what we call the human side of smart manufacturing, and getting it right is just as important as deploying the technology itself.
What exactly is the human side? It’s the recognition that, for all the advanced tools and machinery, and the software that runs them, most fabs still depend on skilled workers to not only move the WIP around the factory floor, but also make decisions that are integral to the manufacturing process itself. As such, these workers are deeply invested in how the fab runs and take pride in the job they do.
Sensitive change management is critical
For implementation of smart technology to succeed, the human side of the transition has to be managed with skill, sensitivity and awareness. It’s not easy to shift existing work practices in any industry, and this is particularly the case within the semiconductor sector, which is used to doing things its own way.
Cutting-edge disruptive technologies are more often than not born in the minds of academics who, despite offering an innovative solution, may have a limited understanding of the inner workings of a fab. As a result, they can fail to take into account the complex implications of their technology and how the adoption phase can impact the people working with it. This is one of the reasons why fabs tend to stick with implementing conventional or in-house solutions. Despite being far less sophisticated, these technologies are built with an appreciation of the realities of a factory and the people who work there. Subsequently, the adoption process is smoother and, although it may not provide radical performance improvements, the impact can be more positive for the fab and its workers.
The key point here then is that, in order for a disruptive smart technology to be implemented successfully, it is critical to have a comprehensive understanding of a fab and a sensitive approach to human change management. Resistance to change is only natural and is to be expected, which is why from the word go, we work side-by-side with our clients to ensure that everybody is on board with changes to the way the fab works, because new technology on its own is not a silver bullet. Fabs don’t conform to theoretical models, but are subject to all manner of real world influences, with the human factor being especially strong.
The Flexciton approach
There are specific steps that we take to make the change management process as successful as possible:
Understand their challenges
To support the change management process, we build close relationships with our clients – not only to create trust, but also to develop a deep understanding of how their current processes work and how production has been executed so far. We have to identify both the objectives and ambitions of the management and the specific challenges and pain points that operators are facing on the shop floor. We do this by shadowing the roles of everyone at the fab who will be affected by the new implementation.
Educate and explain
Change management must follow a systematic methodology, but every fab is different, and so there’s no such thing as a standardised rollout. We understand that our technology will change the way in which both operators and engineers work, which is why the onus is on us to educate and explain why these changes are necessary – as already noted, unless something has gone disastrously wrong, people tend to be resistant to change, particularly if they think they are already doing a perfectly good job. To aid this transition, we always strive to give as much context to the decision-making process as possible.
Establish champions
As such, it is vital that we also establish client champions of the new solution who are already trusted by the fab’s staff, and can help navigate the acceptance process. This is particularly important if, for instance, the decisions that our advanced technology is suggesting initially seem counter-intuitive to those who are familiar and comfortable with old procedures.
Act on feedback
And just as important as demonstrating the results our technology is delivering in a way that’s easy to understand, we also regularly capture user feedback during the rollout period to see where our product and the user experience can be improved. Implementation is a constant process of testing and tweaking to produce the best possible results, and that requires an honest, two-way relationship to be in place. We regularly put new features into our product based on feedback from the shop floor, and it’s always satisfying to hear how we’ve improved operators’ ability to do their jobs as a result.
To undertake a successful smart manufacturing implementation, particularly as a third party vendor, it’s not enough to just have an innovative technology solution. To be a genuine change maker, you need to understand that in the real world, it’s the people that matter as much as the technology. This is why we always set out to build a strong partnership with the fabs that we work with, becoming much more than just an external vendor. Our team is committed to delivering on the KPIs that are targeted by our clients, which doesn’t stop at providing the best possible solution. We also have to understand the people who use it and ensure their adoption of our technology is a smooth and positive process.

The semiconductor industry is set to receive $1tn in investment over the next six years, driven by AI and advanced technologies, with over 100 new wafer fabs expected. However, labor shortages continue to pose a challenge, pushing the need for autonomous wafer fabs to ensure continued growth.
Over the next 6 years, the semiconductor industry is set to receive around $1tn in investment. The opportunities for growth – driven by the rapid rise of AI, autonomous and electric vehicles, and high-performance computing – are enormous. To support this anticipated growth, over 100 new wafer fabs are expected to emerge worldwide in the coming years (Ajit Manocha, SEMI 2024).
However, a significant challenge looms: labor. In the US, one-third of semiconductor workers are now aged 55 or older. Younger generations are increasingly drawn to giants like Google, Apple and Meta for their exciting technological innovation and brand prestige, making it difficult for semiconductor employers to compete. In recent years, the likelihood of employees leaving their jobs in the semiconductor sector has risen by 13% (McKinsey, 2024).
To operate these new fabs effectively, the industry must find a solution. The Autonomous Wafer Fab, a self-optimizing facility with minimal human intervention and seamless production, is looking increasingly likely to be the solution chipmakers need. This vision, long held by the industry, now needs to be accelerated due to current labor pressures.
Thankfully, rapid advancements in artificial intelligence (AI) and Internet of Things (IoT) mean that the Autonomous Wafer Fab is no longer a distant dream but an attainable goal. In this blog, we will explore what an Autonomous Wafer Fab will look like, how we can achieve this milestone, the expected outcomes, and the timeline for reaching this transformative state.
What will an Autonomous Wafer Fab look like?
Imagine a wafer fab where the entire production process is seamlessly interconnected and self-regulating, free to make decisions on its own. In this autonomous environment, advanced algorithms, IoT, AI and optimization technologies work in harmony to optimize every aspect of the manufacturing process. From daily manufacturing decisions to product quality control and fault prediction, every step is meticulously coordinated without the need for human intervention.
Key features of an Autonomous Wafer Fab:
Intelligent Scheduling and Planning: The heart of the autonomous fab lies in its scheduling and planning capabilities. By leveraging advancements such as Autonomous Scheduling Technology (AST), the fab has the power to exhaustively evaluate billions of potential scenarios and guarantee the optimal course for production. This ensures that all constraints and variables are considered, leading to superior outcomes in terms of throughput, cycle time, and on-time delivery.
Real-Time Adaptability: An autonomous fab is equipped with sensors and IoT devices that continuously monitor the production environment. These devices can feed real-time data into the scheduling system, allowing it to dynamically adjust schedules and production plans in response to any changes or disruptions.
Digital Twin: Digital Twin technology mirrors real-time operations through storing masses of data from sensors and IoT devices. This standardized data schema allows for rapid introduction of new technologies and better scalability. Moreover, by simulating production processes, it helps to model possible scenarios – such as KPI adjustments – within the specific constraints of the fab.
Predictive maintenance: Predictive maintenance systems will anticipate equipment failures before they occur, reducing downtime and extending the lifespan of critical machinery. This proactive approach ensures that the fab operates at peak efficiency with minimal interruptions. Robotics will carry out the physical maintenance tasks identified by these systems, and when human intervention is necessary, remote maintenance capabilities will allow technicians to diagnose and address issues without being on-site.
The Control Room: In an autonomous fab, decision-making is driven by data and algorithms. The interconnected system can balance trade-offs between competing objectives, such as maximizing throughput while minimizing cycle time, with unparalleled precision. That said, critical decisions such as overall fab objectives may still be left to humans in the “control room”, who could be on the fab site or 9000 km away…
How can we get there?
Achieving the vision of an Autonomous Wafer Fab requires a multi-faceted approach that integrates technological innovation, strategic investments, and a cultural shift towards embracing automation. Here are the key steps to pave the way:
A Robust Roadmap: All fabs within an organization need to have a common vision. Key milestones need to be laid out to help navigate each fab through the transition with clear actions at each stage. SEMI’s smart manufacturing roadmap offers an insight into what this could look like.
Investing in Novel Technologies: The pivotal step towards autonomy is investing in the latest technologies, including AI, machine learning, AST, and IoT. These technologies form the backbone of the autonomous fab, enabling intelligent planning and scheduling, real-time monitoring, and adaptive control.
Data Integration and Analytics: A crucial aspect of autonomy is the seamless integration of data from various sources within the fab. By harnessing big data analytics, fabs can not only gain deep insights into their operations, but they will have the correct data in place to support autonomous systems further down the line.
Developing Skilled Workforce: While the goal is to minimize human intervention, the semiconductor industry will still require skilled professionals who can manage and maintain advanced systems. Investing in workforce training and development to fill the current void is essential to ensure a smooth transition.
Collaborative Ecosystem: Even the biggest of chipmakers is unlikely to reach the autonomous fab all on their own. Collaboration with technology providers, research institutions, and industry partners will be key. Sharing knowledge and best practices can accelerate the development and deployment of autonomous solutions.
Pilot Programs and Gradual Implementation: Transitioning to an autonomous fab should be approached incrementally. Starting with pilot programs to test and refine technologies in a controlled environment will help identify challenges and demonstrate the benefits. Gradual implementation allows for continuous improvement and adaptation.
How will fabs benefit?

From guaranteed KPI improvements to reducing fab workload by 50%, this blog introduces some of the benefits of Autonomous Scheduling Technology (AST) and how it contrasts with the scheduling status quo.
In the fast-paced world of semiconductor manufacturing, efficient production scheduling is crucial for chipmakers to maintain competitiveness and profitability. The scheduling methods used in wafer fabs can be classified into two main categories: heuristics and mathematical optimization. Both methods aim to achieve the same goal: to provide the best schedules within their capabilities. However, because they utilize different problem-solving methodologies, the outcome is dramatically different. Simply put, heuristics generates solutions by making decisions based on if-then rules predefined by a human, while optimization algorithms search through billions of possible scenarios to automatically select the most optimal one.
Autonomous Scheduling Technology (AST) features mathematical optimization combined with smart decomposition, allowing the quick delivery of optimal production schedules. Whether you are a fab manager or industrial engineer, the experience and results of applying Autonomous Scheduling in your fab are fundamentally different compared to a heuristic scheduler.
Here's how switching to AST can impact your fab.
Consistent and Superior KPIs Guaranteed
Autonomous Scheduling Technology (AST) evaluates all constraints and variables in the production process simultaneously, ensuring optimal decision-making. Unlike heuristics schedulers, which require ongoing trial and error with if-then rules to solve the problem, AST allows the user to balance trade-offs between high level fab objectives. With its forward-looking capability, it can assess the consequences of scheduling decisions across the entire production horizon and generate schedules that guarantee that the fab's global objectives are met. The tests we have conducted against a heuristic-based scheduler have proven that Autonomous Scheduling delivered superior results. Book a demo to find out more.
Never miss a shipment
One of the most critical aspects of fab operations is meeting On-Time-Delivery deadlines. With AST, schedules are optimized towards specific fab objectives, ensuring that production targets align with business goals. Mark Patton, Director of Manufacturing Seagate Springtown, confirmed that adopting Autonomous Scheduling in his fab allowed him to:
"improve our predictability of delivery by meeting weekly customer commits. With a lengthy cycle time build, this predictability and linearity has been key to enabling the successful delivery and execution of meeting commits consistently."
Reduced workload (by at least 50%)
The reactive nature of heuristic-based schedulers places a significant burden on industrial engineers, who must constantly – and manually – tune rules and adjust parameters. To ensure these systems run optimally, fab managers must dedicate at least one industrial engineer to working full-time on maintaining them. With AST, the workload is significantly reduced due to the system's ability to optimize schedules autonomously (without human intervention). This means there will be no more firefighting when the WIP profile changes. This reduction in labor intensity frees up engineers to engage in value-added activities.
Reduced rework, improved yield
Some areas of a fab are notoriously challenging to optimize. For example, the diffusion and clean area is home to very complex time constraints, also known as timelinks. When timelinks are violated, wafers either require rework or must be scrapped. Either way, it's a considerable cost for a fab. Autonomous Scheduling Technology is highly effective at managing conflicting KPIs with its multi-objective optimization capabilities. AST dynamically adjusts to changes in the fabrication process to consistently eliminate timelink violations whilst maximizing throughput.
Confidence in Balancing Trade-offs
With its ability to look ahead, Autonomous Scheduling Technology can predict the consequences of different trade-off settings. This capability is particularly valuable when balancing competing objectives like throughput and cycle time. Users of legacy schedulers would typically move sliders to adjust the settings and wait a considerable amount of time to assess whether the adjustments generate the desired scheduling behavior. If not, further iterations are required, and the process repeats. In contrast, AST can evaluate billions of potential scenarios and determine the optimal balance between conflicting goals. For example, it can predict the exact impact of prioritizing larger batches over shorter cycle times, allowing fab managers to make informed decisions with confidence. This strategic foresight ensures that the best possible trade-offs are made, optimizing the whole fab to meet overarching objectives.
Conclusion
In an industry where efficiency and precision are paramount, Autonomous Scheduling Technology provides a distinct competitive advantage. It equips fabs with the tools to consistently outperform legacy systems, streamline operations, and ultimately drive greater profitability. By investing today in upgrading their legacy scheduling systems to Autonomous Scheduling Technology, wafer fabs are not only optimizing their current operations but also taking an important step toward the autonomous fab of the future.
