Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To form a light spot which is greatly reduced in size by further converging light, which is converged to the limit of diffraction, through a Fresnel diffraction phenomenon for high-density recording. SOLUTION: The light which is converged by an objective 3 has its phase and quantity spatially controlled by a diffraction optical element 6 nearby its depth of focus to re-form a light spot on an optical disk.

IPC: H01L21/304
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To increase the regeneration rate of a faulty polished wafer and prevent reduction of a strength of a reproduced wafer caused by reproducing treatment. SOLUTION: The surface of a semiconductor wafer after etched is polished and inspected for its planarity. A wafer failing to meet a reference value and judged as having faulty planarity is subjected to a plasma etching for its reproduction.
