    Abstract: PROBLEM TO BE SOLVED: To prevent side etching at both longitudinal ends of a plate-like structure. SOLUTION: In this manufacturing method for a semiconductor structure, a semiconductor substrate is etched to form the plate-like structure with side faces formed as (111) faces almost perpendicular to the main surface of the substrate.

With the formation of the (111) faces by wet etching and the dissolution of side etching by dry etching, the plate-like structure is accurately formed with a required minimum produced area. The formed plate-like structure is used as a mirror in an optical switching device. COPYRIGHT: (C)2005,JPO&NCIPI
