Title: Dry etching
Inventor: KADOMURA SHINGO
IPC: H01L21/302
Filed: 1988-08-27
Abstract: PURPOSE:To reduce an etching rate or stop the etching and to execute a good etching operation by a method wherein a hydrogen introduction region is formed in a material layer and a reaction gas containing fluorine as a main etchant is taken in by using hydrogen when the etching operation progresses so as to reach the hydrogen introduction region. CONSTITUTION:A silicon nitride layer 2 is formed on a substrate 1. Ions of hydrogen in large quantities are implanted into a surface part of the nitride layer 2; a hydrogen introduction region 3 is formed. A silicon oxide layer 4 is laminated on the nitride layer 2 where the region 3 has been formed. A resist layer 5 is formed on the oxide layer 4; the resist layer 5 is exposed selectively and developed; a resist mask having an opening part 6 is formed. An etching operation is executed; the nitride layer 2 is exposed; hydrogen in the region 3 is extricated and takes in F* as a main etchant in a plasma. An etching rate of the nitride layer 2 is slowed; an anisotropic etching operation with a selection ratio of the oxide layer 4 to the nitride layer 2 can be executed. Thereby, a good etching operation can be executed.

Title: Connector for printed substrate
Inventor: KAIWA RYOICHI
IPC: H01R12/22
Filed: 1990-08-10
Abstract: PURPOSE:To make a connector having a large number of contact points small and lower the force to insert and draw the connector by separating the materials and structures composed of contact points of a high resistance circuit and contact points of a low resistance circuit, respectively. CONSTITUTION:Contact terminals 15a, 15b, 16a, 16b of printed substrates 11, 12 are connected with a high resistance circuit and soldered terminal holes 13a, 13b, 14a, 14b are connected with a low resistance circuit. The connection with the high resistance circuit is carried out by connecting contactor terminals exposed in both end faces of a conductive rubber 31 with the contact terminals 15a, 15b, 16a, 16b. The connection with the low resistance circuit is carried out by using metal-made female contacts 23a, 23b and male contacts 24a, 24b. Since the metal contacts which need large force to be inserted and drawn out are limited to the use for connecting the contact parts of low resistance, the force to be inserted and drawn out of the whole connector becomes low.
