Title: Semiconductor device and its manufacture
Inventor: ESHITA TAKASHI
IPC: H01L21/205
Filed: 1990-11-30
Abstract: PURPOSE:To confine carriers in only an active part for an element and to insulate and isolate them by a structure wherein a semiconductor constituting the active part for the element is filled in a semiconductor whose band gap is larger than that of the semiconductor. CONSTITUTION:A semiconductor substrate 3 is formed of a second III-V compound semiconductor whose band gap is small as compared with a first III compound semiconductor, i.e., AlGaAs 2. A channel region for an FET is formed as an active layer at the inside of a second epitaxial layer 1; it is formed of a source electrode 4, a drain electrode 5 and a gate electrode 6. The second epitaxial layer GaAs 1 to which the electrodes have been applied is of a planar structure; the interface composed of side faces 1a and a bottom face 1b is bonded to AlGaAs (whose band gap is large). Consequently, carriers for the FET cannot go over the band gap at the interface and are confined at the inside of a first epitaxial layer 2.

Title: Silicon nitride package and its manufacture
Inventor: TATEMATSU KAZUO
IPC: H01L23/08
Filed: 1989-12-29
Abstract: PURPOSE:To improve mechanical strength by embedding a conductor section which comprises a high melting point metal into a silicon nitride sintered body or forming the conductor section on the surface of the sintered body. CONSTITUTION:A silicon nitride-based package is produced by embedding a high melting metal, which serves as a conductor section, into a silicon nitride sintered body or forming the conductor section on the surface of the sintered body. Since this package comprises a material called silicon nitride whose expansion coefficient is near to that of silicon, no trouble is produced as to the mismatching with the silicon chip in thermal expansion. High melting point metals, such as tungsten (W) or molybdenum (Mo) are adopted for the formation of a conductor section of the package, which makes it possible to obtain a package which can withstand high temperature service and match with silicon nitride. It is, therefore, possible to enhance the mechanical strength.

Abstract: PURPOSE:To obtain a disc spring capable of evenly and circumferentially deflecting and greatly deforming without deviation of stress and operating direction at the time of deflection by forming the cross section of the disc spring into a corrugated shape have spiral ripples from an optional point around a central circle of the material plate, and forming the spiral ripples so as to be inclined toward the central circle. CONSTITUTION:The cross section of a disc spring D is formed into a corrugated shape having spiral ripples P3 from an optional point around a central circle 10, and the spiral ripples P3 are formed to be inclined toward the central circle 10. When pressing force is applied to an optional point on the surface of the coned disk spring D, the disc spring D of this configuration transmits deflection due to the pressing force through the spiral ripples P3 to all the areas, and is deflected evenly and circumferentially without deviation of generated stress. Further, since the deflection is promoted by means of the inclination of the ripples P3, the coned disc spring is greatly deflected. Thus, when the coned disc spring D is applied to a diaphragm, the diaphragm can hold a constant restoring force for a long period of time due to this characteristics of the coned disc spring D.
