Abstract:
A method for reinforcing a bond pad in a semiconductor integrated circuit comprising:forming a hydrogen silsesquioxane first dielectric layer: patterning said hydrogen silsesquioxane first dielectric layer in a predetermined area into a predetermined pattern having a plurality of vacant areas; forming a layer of reinforcing material above said patterned hydrogen silsesquioxane first dielectric layer, filling said vacant areas therein; removing said reinforcing material except for said filled vacant area, whereby a uniformly flat surface is formed and said hydrogen silsesquioxane first dielectric layer is transformed into a reinforcing layer; forming a second dielectric layer above said uniformly flat surface of said reinforcing hydrogen silsesquioxane first dielectric layer; and forming a bond pad on said second dielectric layer above said reinforcing hydrogen silsesquioxane first dielectric layer.
