Before a single transistor can be created or a circuit pattern drawn, we must first produce the perfect foundation, the silicon wafer. In this chapter, we’ll trace the remarkable journey of how ordinary sand is transformed into ultra-pure, mirror-polished silicon discs that serve as the starting canvas for chip manufacturing.

摘要

Before a single transistor can be created or a circuit pattern drawn, we must first produce the perfect foundation, the silicon wafer. In this chapter, we’ll trace the remarkable journey of how ordinary sand is transformed into ultra-pure, mirror-polished silicon discs that serve as the starting canvas for chip manufacturing.
