WebThe word lithography comes from the Greek lithos, meaning stones, and graphia, meaning to write. It means quite literally writing on stones. In the case of semiconductor lithography, our stones are silicon wafers and our patterns are written with a light -sensitive polymer called photoresist. WebLithography is a crucial step in the chipmaking process, because it determines just how small the transistors on a chip can be. During this stage, the chip wafer is inserted into a …
