WebExplanation: Dry oxidation is used to achieve high-quality oxide growth. Dry oxidation produces a very good quality of oxide that's why dry oxidation is preferred over wet oxidation to grow thin gate oxide in CMOS fabrication. Dry oxidation is used to form thin oxide films and give better electrical properties. It is slow compare to wet oxidation. WebAn oxidized Si wafer has an initial field oxide thickness of xi. Patterned windows of the field oxide are completely cleared by etching. Dry O2at 900°C is then used to grow a thin gate oxide in these cleared regions. a.
