Optimizing Fab Efficiency: Advanced Production Scheduling in a Seagate Technology Wafer Fab

How Seagate Technology is improving cycle time and fab efficiency with no extra capital expenditure 

Ready to bring smart technology into your fab?

Watch the case study and learn how Seagate implementing a novel scheduling optimization solution helped Seagate to reduce cycle time across almost the entire fab and of some toolsets even by 40%.

‘For us here at Seagate, high factory utilisation is key. We already run at about 100%. So we were looking to optimise and improve capacity, cycle time and predictability, as well as the ability to schedule and adapt to uncertain situations as optimally as possible. We found an ideal partner in Flexciton.’

In this case study you will discover:

  • The results and key benefits realized by Seagate during the implementation process

  • How objective-driven scheduler enables Seagate to specify the KPIs most important to each toolset, improving cycle time, batching, throughput, OTD, or any other target KPI

  • What are the three levels of scheduling that allow optimizing the entire fab, from Wafer Start decisions down to the sequencing of lots on individual load ports

  • How this new approach to scheduling can help you to optimize the WIP flow whilst automatically adapting to random events and the unique characteristics of the fab

About Seagate

Seagate Technology is a data storage company and the Springtown facility is at the heart of the $25Billion dollar data storage industry. Seagate opened its wafer facility in Derry in N. Ireland in 1993. 


There are only five of these types of facilities in the world which the Springtown is the largest. Seagate has a second wafer facility in Minnesota, which mirrors what they produce in Derry. The Springtown facility supplies approx. 25% of all read-write heads for hard drives globally. www.seagate.com
