Patent ID: 8491360

Claim:
A chemical-mechanical planarization polishing pad comprising: a performed three-dimensional network of interconnecting elements and a polymer filler material, wherein said interconnecting elements include interconnecting junction points that are present at a density of 1 interconnecting junction point/cm 3 to 1000 interconnecting junction points/cm 3 , and wherein said interconnecting elements have a length between interconnecting junction points of 0.1 microns to 20 cm wherein said three-dimensional network defines square or rectangular geometry that is present through-out said pad; wherein the interconnecting elements comprise fibers; wherein the fibers comprise fibers that are soluble in a liquid slurry; and wherein the soluble fibers dissolve in the liquid slurry leaving void spaces on and under a surface of the pad creating micron sized channels and tunnels for distribution of the liquid slurry throughout the pad.
