IBM invented semiconductor manufacturing automation
IBM's Project SWIFT revolutionized semiconductor manufacturing by achieving a fully automated wafer-fabrication line that could produce integrated circuits in less than a day. Led by Bill Harding, the project introduced groundbreaking innovations that set a new standard for the semiconductor industry. Despite the increased complexity of modern integrated circuits, the turnaround time achieved by SWIFT has never been matched.
- ▪Bill Harding envisioned a fully automated wafer-fabrication line in 1970 that would produce integrated circuits in less than one day.
- ▪Project SWIFT averaged 5 hours to complete each layer of its fabrication process, significantly faster than today's industry average of 36 hours.
- ▪Many of the innovations from Project SWIFT are now commonplace in modern chip fabrication plants, reflecting its lasting impact on the semiconductor industry.

Each sector contained in an enclosure all of the wafer-processing equipment needed to accomplish a segment of the fabrication process between lithographic-pattern exposures.
