Patent ID: 7662712

Claim:
A method for fabricating a semiconductor device having an ultraviolet (UV) blocking layer comprising the steps of: providing a semiconductor substrate comprising a patterned metal conductor layer, the patterned metal conductor layer comprising metal conductors separated by gaps to create a first surface contour with first raised portions defining first gaps therebetween; forming a dielectric separation layer overlying the semiconductor substrate and patterned metal conductor layer; the dielectric separation layer forming step carried out so that the dielectric separation layer follows the first surface contour to create a second surface contour with second raised portions defining second gaps therebetween; forming a UV blocking layer of super silicon enriched oxide, having a silicon atomic concentration is at least about 70%, overlying and directly contacting said separation layer; the UV blocking layer forming step carried out so that the UV blocking layer follows the second surface contour to create a third surface contour with second raised portions defining third gaps therebetween; and the UV blocking layer forming step being carried out with the UV blocking layer having an extinction coefficient of at least about 1.7 at a wavelength of 248 nm for ultraviolet blocking.
