Abstract:
A semiconductor device having patterned conductors on a common conducting level, the device comprising:patterned conductors overlying a substrate, the patterned conductors comprising a plurality of high aspect ratio conductors and a plurality of low aspect ratio conductors, the patterned conductors having a first thickness; an HDP oxide layer overlying and between the patterned conductors, the HDP oxide layer having a second thicknessâ€”as measured in one or more gaps between the conductorsâ€”greater than or approximately equal to the first thickness; and an oxide polish layer overlying the HDP oxide layer, the polish layer having a substantially planar top surface; the layer of patterned conductors, HDP oxide layer, and oxide polish layer having a combined thickness of at least 150% of the first thickness.
