Title: Manufacture of silicon thin film piezoresistance element
Inventor: TAMURA MORIO
IPC: H01L21/20
Filed: 1988-09-27
Abstract: PURPOSE:To obtain a high quality of silicon thin film piezo resistance element at low cost by decomposing mixed gas which is made by adding doping gas to raw gas in a plasma atmosphere, and forming an amorphous thin film on a substrate which is under specific temperature conditions and heat-treating it. CONSTITUTION:Monosilane from a bomb 6 for raw gas and diborane from a bomb 7 for doping gas are introduced into a bell jar 1 through mass-flow controllers 14 and 15, respectively. Thereafter, high frequency power of 20-100W is applied from a high frequency power source 5 to an upper electrode 2 so as to generate plasma P, and by activating mixed gas of monosilane and diborane an amorphous silicon thin film is formed on a substrate 29. Next, heat treatment is done to make the amorphous silicon thin film a crystalline silicon film. Through the amorphous silicon thin film is greater in resistivity than the crystalline silicon thin film, by doing this heat treatment the silicon thin film changes from amorphous to polycrystalline quality, whereby the resistivity changes.

Abstract: PURPOSE:To prevent metal foil burrs from being produced along the edge of a packaging recess for the elimination of short-circuiting by a method wherein a part is removed of a metal foil deposited on an insulating substrate and then a packaging recess is provided by counterboring in the surface of the insulating substrate. CONSTITUTION:A metal foil 3 for example of copper is deposited on the surface of an insulating substrate 1. The metal film 3 is locally removed, for example from the middle of the insulating substrate 1, for the formation of a packaging recess 2. The section of the insulating substrate 1 removed of its metal film 3 is subjected to a counterboring process, which is accomplished by using for example an end mill 8, for the formation of a packaging recess 2. A circuit is formed in the metal foil 3, a semiconductor chip 4 is placed in the packaging recess 2, and the chip 4 and the circuit are electrically connected to each other. In this manufacturing method, no burrs are to be produced out of the metal foil 3 along the edge of the packaging recess 2, which eventually prevents shortcircuiting.

Filed: 1992-09-10
Abstract: PURPOSE:To enhance the insulation characteristic between scanning lines and pixel electrodes while the resistance value of the scanning lines is maintained low by incorporating nitrogen into the oxidized insulating film on the scanning lines. CONSTITUTION:The scanning lines having gate electrodes 5 are formed on an insulating substrate 1 consisting of glass, etc., and the oxidized insulating film 11 is provided to cover these scanning lines.
