Abstract
A semiconductor device (11) has a spin on glass layer or region, and the spin on glass has a method of synthesis and use. The spin on glass composition is formed which comprises on the order of 0% to 20% by volume of tetraethylorthosilicate (TEOS), on the order of 0.01% to 20% by volume of tetraethylorthogermanate (TEOG), on the order of 0% to 1% by volume the equivalent of nitric acid (HNO.sub.3), on the order of 70% to 85% by volume of alcohol, and a remaining balance of the spin on glass composition being water. The spin on glass is applied to a semiconductor substrate and heated and/or densified to form the spin on glass layer or region.
