Abstract: The present invention relates to a polishing pad which is characterized in that it has a polishing layer of rubber A-type microhardness at least 80 DEG and a cushioning layer of bulk modulus at least 40 MPa and tensile modulus in the range 0.1 MPa to 20 MPa, and to a polishing device which is characterized in that a semiconductor substrate is fixed to the polishing head, and an aforesaid polishing pad is fixed to the polishing platen so that the polishing layer faces the semiconductor substrate, and by rotating the aforesaid polishing head or the polishing platen, or both, the semiconductor substrate is polished. With the polishing device or polishing pad of the present invention for use in the mechanical planarizing process wherein the surface of the insulating layers or metal interconnects formed on a semiconductor substrate are smoothened, it is possible to uniformly planarize the entire semiconductor face and perform uniform polishing close up to the wafer edge and, furthermore, it is possible to provide a technique for achieving both uniformity and planarity under conditions of high platen rotation rate.

Abstract: 72643-1 A gas separation membrane with excellent gas separation properties. The gas separation membrane of the present invention is substantially free from pinholes and consists essentially of a crosslinked polyolefin or a crosslinked polyarylene oxide. The gas separation membrane of the present invention is produced by evaporating a solution containing a polyolefin or a polyarylene oxide each having an active functional group which can autogenically form crosslinking sites therebetween.
