Title: Mirror surface polishing method of chamfering surface of semiconductor wafer and its device
Inventor: TSURUTA SHOJI
IPC: H01L21/304
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To attain size reduction of a polishing device of a chamfering surface, and polish the chamfering surface with high throughput by simultaneously removing a lateral directional stripe and a longitudinal directional stripe of the chamfering surface. SOLUTION: A semiconductor wafer W is installed in a support member, and is driven in rotation by a motor. Polishing cloth of a polishing drum is pressed to and contacted with a chamfering surface of this wafer, and the chamfering surface is mechanochemically polished. A polishing liquid containing free abrasive grains is supplied to the polishing cloth. The polishing cloth performs mirror surface polishing on the chamfering surface while being viscoelastically deformed. At this time, the polishing cloth is pressed to and contacted with the chamfering surface of the wafer while rotating the longitudinal direction (the direction orthogonal to the wafer circumferential direction) X. As a result, a circumferntial directional stripe is not generated on the chamfering surface. Similarly, a stripe does not remain in the longitudinal direction. It is because a wide surface of the polishing cloth contacts with the chamfering surface. At the same time, productivity can be enhanced.

Title: Multistage switch
Inventor: ISHIGURO KAZUYOSHI
IPC: H01H21/14
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To improve a usage feeling in a multistage switch. SOLUTION: The height of a step difference part 36 for deciding force, for pressing a fixed side contact member 32 by a moving side contact member 34, is differed in accordance with the size of an electric current to open/close by a contact. Resultantly, force, received by the contact member 34 via an engaging ball 40, is increased with the height of the step difference part 36 increased, thereby ensuring contact pressure needed to the electric current to open/close by the contact. Moreover when a moderation part, for preparing the moderation feeling of a multistage switch, is formed integrally with a contact part, constitution can be made wherein operating force can be changed by changing the shape of the crest and valley of the moderation part.
