ABSTRACT:
The present invention develops an opaque or translucent glass film for use in semiconductor fabrication processes, such as in EPROMs or radio frequency integrated circuits. The opaque or translucent film is developed by forming an glass layer while and introducing a light blocking pigment into the glass layer. The light blocking pigment is made up of a metal oxide, such as titanium oxide (TiO.sub.2), an organic dye, bone ash, or dispersed metal particles. The glass layer is made up of spin on glass.
