Title: Dry etching method
Inventor: ARIKADO TSUNETOSHI
IPC: C23F1/00
Filed: 1980-11-21
Abstract: PURPOSE: To easily remove etching residue, when an etched pattern is formed in an oxide film on the surface of a Si wafer in a dry etching process involving reactive ion etching, by irradiating laser beams to the etched part.  
     CONSTITUTION: A phosphorus silicide glass film 15 is accumulated on the whole surface of a field oxide film 12, a gate oxide film 13 and a gate electrode 14 on a silicon wafer 11. This glass film-formed Si wafer is heated to diffuse phosphorus into the surface layer of the wafer 11. Thus, a cource and drains 16a, 16b as n +  type diffusion layers are formed. Thereafter, a positive photoresist film 17 is applied to the film 15, and a contact hole-forming resist pattern is formed by an optical etching process. A contact hole 18 is then formed in a reactive ion etching process using the gaseous mixture of CF 4  and H 2 . Laser beams are irradiated to the contact hole 18 in vacuo, to remove C, F-contng. residue the hole 18. Thus, the electric resistance of the contact hole 18 is reduced.

Title: Rotation detector
Inventor: KUBO SHOICHI
IPC: G01P3/487
Filed: 1987-07-01
Abstract: PURPOSE:To reduce a magnetizing pitch, by building a rotor using an aluminum- manganese-carbon based alloy magnet. CONSTITUTION:The use of an aluminum-manganese-carbon based alloy magnet for a ring magnet 2 of a rotor eliminates changes in dimensions with respect to humidity or almost does with respect to temperature. The ring magnet 2 is machined to the roundness with a lathe or the like after a shaft 1 is fixed by an adhesive material or by press fitting. Hence, the ring magnet 2 can be arranged close to a magnetic sensor 3, for example, with a gap of 0.05mm therebetween, which permits increase in the number of magnetic poles in magnetization to 1024 with the magnetization pitch P set at 0.077mm. As a result, the arrangement of numerous magnetic poles is made possible with a reduction in the pitch P to produce a rotation detector with high resolutions. On the other hand, when the number of magnetic poles in magnetization is fixed, the pitch P can be reduced thereby enabling miniaturization of the apparatus with a smaller outer diameter of the ring magnet.
