Title: Semiconductor device
Inventor: YOU SEIHATSU
IPC: H01L29/78
Filed: 1988-03-24
Abstract: PURPOSE:To prevent a parasitic bipolar transistor effect by forming, adjacent to a source region, a high impurity-concentration layer for forming a well contact having a conductivity type opposite to that of the source region. CONSTITUTION:A P<+> type well contact diffusion layer 9 is formed adjoined to an N<+> type source region 3 while a diffusion layer 10 having impurity concentration slightly higher than a P-type well region and lower than the impurity concentration of the P<+> type well contact diffusion layer 9 is shaped on at least the source region side to a shape that these region 3 and layer 9 are included. Consequently, the N<+> type source region 3 and the P<+> type well contact diffusion layer 9 are constituted adjacently, and a common electrode is formed, thus bringing both region 3 and layer 9 to the same potential (ground potential) at all times. Since the P-type diffusion layer 10 is formed so as to surround both region 3 and layer 9, a distance contributing to the resistance (Rwell) of the well region of ON currents (hole currents) of a parasitic bipolar transistor is shortened while the conductivity of the P-type diffusion layer 10 is increased. Accordingly, a parasitic bipolar transistor effect is prevented.

Filed: 1992-03-27
Abstract: PURPOSE:To prevent a heat flow using a section between metallic thin-films having high thermal conductivity as a heat conduction path and improve the heat-insulating effect of a heat-insulating box body by parting the metallic thin-film layer oppositely faced to the box-body inside of the heat-insulating box body between a temperature difference region in the box body. CONSTITUTION:An external aluminum thin-film layer 11 is positioned on the outer shell 4 side, parting width 13 is located at the position of the boundary of a refrigerating room 2 and a coldroom 3, and a vacuum heat-insulating panel 6 is housed in a wall surface. An internal aluminum thin-film layer is divided into 12a and 12b in approximately 10% parting width 13 of a distance between the refrigerating room 2 and the coldroom 3, thus reducing the quantity of a heat flow to a factor of several tens. The parting width 13 is formed through a method, etc., in which an aluminum foil laminate shaped as the aluminum thin-film layer or deposited aluminum is removed through etching at the position of the parting width 13. A heat conduction path between a compressor and a temperature difference region on the inwall side of the heat-insulating box body of the aluminum thin-film layer is interrupted, thus realizing the heat-insulating box body having a high heat-insulating effect.

Title: Aqueous adhesive composition
Inventor: INOUE TAISEI
IPC: C09J201/00
Filed: 1981-05-12
Abstract: PURPOSE: To obtain an aqueous adhesive composition that would not bring about defective bonding due to dry bonding phenomenon, by incorporating a high molecular substance having a higher moisture absorbency.  
     CONSTITUTION: The aqueous adhesive composition contains 0.1W10.0% high molecular substance capable of absorbing and retaining a quantity of moisture ≥50 times its own weight (e.g. a gel containing higher amounts of water and a high molecular weight such as a copolymer of vinyl acetate with acrylic acid, a copolymer of isobutene with maleic anhydride, etc.). Becuase of the ability of said gel in the adhesive composition for retaining the moisture, the moisture in the adhesive applied on an adherend is prevented from dissipating from the adherend surface and from being absorbed in the adherend, and therefore the defective bonding due to dry bonding phenomenon would not result in.

Title: Resin-sealed semiconductor device
Inventor: MINE KATSUTOSHI
IPC: H01L23/31
Filed: 1985-04-05
Abstract: PURPOSE:To enable a semiconductor chip to preserve its excellent resistance to humidity, by forming a cured silicone film such that it covers integrally the surface of the semiconductor chip including bonding pads and that it has a small thickness for preventing it from covering bonding wires. CONSTITUTION:By pouring a high-temperature thermosetting resin 8, a semiconductor chip 3, bonding wires 6 and lead frames as well as the thermosetting resin are expanded. Since the materials of these elements have thermal expansion factors different from each other, stress is produced at the interfaces therebetween. The stress is, however, decreased by the presence of a cured silicone film 7, and the effect thereof to the chip 3 is alleviated. Further, since the wires 4 are not contacted with the interface between the film 7 and the thermosetting resin 8, no disconnection is caused therein. The film 7 is formed to have a thickness of 10mum or less so that the stress from the sealing resin can be decreased. Consequently, a protective film of phosphorus glass, for example, provided on the surface of the chip 3 can be prevented from being cracked. Further, since the bonding pads 4 are covered with the film 7, it is allowed to preserve its excellent resistance to humidity.
