IBM's foray into automated semiconductor fabrication took shape with the ambitious Project SWIFT in the early 1970s, spearheaded by innovative manager William Harding. The primary objective was to develop a fully automated wafer fabrication process that could produce integrated circuits in under a day, a significant enhancement over the labour-intensive month-long production cycles of the time. Harding's team implemented a sophisticated control system utilising the IBM 1800 computer to manage wafer movements efficiently, significantly reducing the need for human intervention and minimising contamination risks in the cleanroom environment.

Among the notable advancements were new non-contact wafer handling techniques and optimised lithography methods that set new standards for efficiency. While the project itself had a limited lifespan, the principles and practices established by SWIFT became foundational in the realm of semiconductor manufacturing. Ultimately, IBM not only reshaped its own production processes but also left an indelible mark on the semiconductor industry as a whole, paving the way for the high-speed automated fabs we see today.
