WebA TEOS-based CVD process is used to deposit a second layer of dielectric, commonly referred to as an intermetal dielectric. This dielectric layer is patterned using a conventional photolithography process to create contact holes to the first level metal which contacts the source/drain regions. Tetraethyl orthosilicate, formally named tetraethoxysilane (TEOS), ethyl silicate is the organic chemical compound with the formula Si(OC2H5)4. TEOS is a colorless liquid. It degrades in water. TEOS is the ethyl ester of orthosilicic acid, Si(OH)4. It is the most prevalent alkoxide of silicon. TEOS is a tetrahedral molecule. Like its many analogues, it is prepared by alc…
