Abstract:
The embodiments relate to a porous polyurethane polishing pad and a process for preparing a semiconductor device by using the same. The porous polyurethane polishing pad comprises a urethane-based prepolymer and a curing agent, and has a thickness of 1.5 to 2.5 mm, a number of pores whose average diameter is 10 to 60 μm, a specific gravity of 0.7 to 0.9 g/cm 3 , a surface hardness at 25° C. of 45 to 65 Shore D, a tensile strength of 15 to 25 N/mm 2 , an elongation of 80 to 250%, an AFM (atomic force microscope) elastic modulus of 30 to 100 MPa measured from a polishing surface in direct contact with an object to be polished to a predetermined depth wherein the predetermined depth is 1 to 10 μm.

Claim (Index 6):
The porous polyurethane polishing pad of  claim 1 , wherein the pores comprise a number of open pores exposed to the outside, the open pores comprise a first open pore and a second open pore that are adjacent to each other and spaced from each other, and the polishing surface is disposed between the first open pore and the second open pore.
