Abstract:
The present invention provides a chemical mechanical (CMP) polishing pad for polishing, for example, a semiconductor substrate, having one or more endpoint detection windows (windows) which at a thickness of 2 mm would have a UV cut-off at a wavelength of 325 nm or lower which are the product of a reaction mixture of (A) from 30 to 56 wt. % of one or more cycloaliphatic diisocyanates or polyisocyanates with (B) from 43 to 69.9999 a polyol mixture of (i) a polymeric diol having an average molecular weight of from 500 to 1,500, such as a polycarbonate diol for hard windows and a polyether polyol for soft windows and (ii) a triol having an average to molecular weight of from 120 to 320 in a weight ratio of (B)(i) polymeric diol to (B)(ii) triol ranging from 1.6:1 to 5.2:1, and a catalyst, preferably a secondary or tertiary amine or bismuth neodecanoate, all weight percent's based on the total solids weight of the reaction mixture.

Claim (Index 7):
The chemical mechanical (CMP) polishing pad as claimed in  claim 1 , wherein the one or more endpoint detection windows is the product of a reaction mixture wherein the mole ratio of isocyanate groups in (A) the cycloaliphatic diisocyanate or polyisocyanate to the number of moles of hydroxyl groups in the (B) polyol mixture ranges from 0.9:1 to 1.10:1.
