http://www.ee.nchu.edu.tw/Pic/CourseItem/1716_ch05.pdf Weboxide (gate oxide 2—1 nm thick) is now deposited all over the wafer. This step is followed by a Polysilicon (0.8-0.5 µm thick) deposition step (CVD). The Polysilicon mask then is used in a lithographic step to to pattern and plasma etch the poly and the silicon and at the end of this step we define the gate regions of the transistors (n and p).
