Title: Manufacture of compound semiconductor integrated circuit capacitor
Inventor: NISHITSUJI MITSURU
IPC: H01L21/8252
Filed: 1991-06-19
Abstract: PURPOSE:To enable a capacitor to be enhanced in breakdown strength and an insulating layer to be formed into a thin film by a method wherein an insulating layer higher than an interlayer insulating film in dielectric constant and a second metal layer are successively laminated on a first metal layer of a capacitive element formed at the same time as a gate electrode. CONSTITUTION:A WSi film is deposited on all the primary surface of a semi- insulating GaAs substrate 1 for the formation of a gate electrode 3 and the first metal layer 2 of a capacitive element. Then, a TaOx film is deposited to serve as the insulator of a capacitive element, a resist mask 8 is applied onto the surface excluding the end of the first metal layer 2 and the gate electrode 3. Only the end of the first metal layer 2 and the gate electrode 3 are etched by reactive ions. In succession, Au is evaporated on all the surface as a second metal layer, a second metal region 5 and a first wiring region 6 are formed on a capacitive element using a resist film as a mask, and the second metal layer of Au is removed. At this point, an Au 7 on the gate electrode 3 is processed at the same time for the formation of a capacitive element and a gate electrode.

Title: Starter
Inventor: SAKAI TOSHIYUKI
IPC: H01H50/20
Filed: 1989-06-09
Abstract: PURPOSE:To reduce the labor in assembly and speedily stop the inertial revolution of an armature by installing one auxiliary contact point by extending a terminal plate and installing the other auxiliary contact point onto a case wall opposed to the terminal plate. CONSTITUTION:An auxiliary contact point 51 is installed at one extension edge by extending a part of a terminal plate 3 into the shift locus of an armature 4. The other auxiliary contact point 52 is installed onto a case wall 61 which is grounded with a magnet switch 6 opposed to the auxiliary contact point 51. When the auxiliary contact points 51 and 52 contact-conduct, the auxiliary contact point 51 conducts a terminal contact point 1A on an armature 7 side. Therefore, the electric current generated by the inertial revolution of the armature 7 flows to the ground from the case wall 61 through the auxiliary contact points 51 and 52 in conduction. Therefore, the labour for assembly can be reduced, and the inertial revolution of the armature can be speedily suspended.

Title: Contamination check system for tunneling microscope
Inventor: IWATSUKI MASASHI
IPC: H01J37/28
Filed: 1989-06-09
Abstract: PURPOSE:To easily check the contamination states of the surfaces of a sample and a probe by varying the distance between the probe and sample surface or an applied voltage and monitoring the variation of a tunneling current.

IPC: H01L21/302
Filed: 1991-05-24
Abstract: PURPOSE:To attain the rapidity, high selectivity, high anisotropy and high damage resistance at about room temperature in the dry-etching method of silicon compound layer. CONSTITUTION:In the dry-etching method, an inter SiO2 layer insulating film is etched away using an etching gas mixed with a chain unsaturated fluorocarbon (FC) base compound such as C3F6, etc., and a cyclic unsaturated FC base compound such as c-C4F6, etc. At this time, these compounds producing two each or more CFn<+> from one molecule contribute to the rapid anisotropical etching step. Furthermore, the deposition of a carbon base polymer can be accelerated at about room temperature due to high C/F ratio so as to enhance the resist selectivity and silicon selectivity. Through these procedures, since any depositing gas such as H2 or hydrocarbon is not used together different from the conventional selectivity enhancing means, the damage by H<+> to the silicon substrate can be avoided.
