How smart production scheduling technology enables significant cycle time improvements in a Seagate Technology wafer fab

Ready to optimize your fab scheduling?

Watch the case study presentation and learn how Seagate’s Springtown facility implemented novel scheduling technology to improve cycle time even by 40% for some toolsets and significantly reduce queue and process time across almost the entire fab.

‘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 presentation you will discover:

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

  • What is the underlying technology that enables generating near-optimal schedules in 4 minutes whilst adapting to fab uncertainty

  • 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 the smart scheduler simultaneously optimizes wafer and reticle scheduling in the fab’s litho area

  • Which key areas of focus have contributed the most to Seagate’s continuous efficiency improvements

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
