Title: Silicon thin film and manufacture thereof
Inventor: ISHIHARA SHINICHIRO
IPC: H01L29/78
Filed: 1986-10-31
Abstract: PURPOSE:To alleviate the stress present on the interface between a substrate and a silicon thin film by a method wherein an amorphous silicon thin film and a crystalline silicon thin film are deposited alternately on a substrate. CONSTITUTION:The silicon thin film 2 on the substrate 1 such as a quartz glass substrate and the like is formed into a four-layer structure, layers 3 and 5 are formed of amorphous silicon, and layers 4 and 6 are formed of crystalline silicon. These silicon thin films are formed using an LPCVD method. When the multilayer structure such as above-mentioned is used, a leak current can be made small. Also, as the stress in the polycrystalline layers 4 and 6 can be alleviated slowly by the amorphous layers 3 and 5, the value of an ON- current can be made larger than the characteristics heretofore in use. The layers are formed into an amorphous state or a crystalline state by having a non-crystalline state, by changing the substrate temperature while a film is being deposited, by using diluted gas, and also by changing the degree of vacuum state.

Title: Method for connecting semiconductor chip
Inventor: SHIFU HIDEJIRO
IPC: H01L21/60
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To improve the connection reliability at the time of connecting a semiconductor chip to a wiring board. SOLUTION: Pre-molded bumps 14 are connected to the aluminum electrodes 12A of a semiconductor chip 10. After the chip 10 is placed on a wiring board 16, the bumps 14 are deformed by pressurizing the bumps 14 in the direction shown by the arrow P. While the bumps 14 are deformed, a sealing resin 18 is injected into the space between the chip 10 and board 16 and cured by heating the resin 18 to a prescribed temperature or higher. As a result, such a stress that restores the bump to the original shape is generated in each bump 14. Therefore, the chip 10 can be connected to the wiring board 16.  In addition, since the bumps 14 are not fixed to the aluminum electrodes 12B of the board 16 and the stresses can be released due to the difference between the coefficients of thermal expansion of the bumps 14 and electrodes 12B, the connection reliability between the chip 10 and board 16 can be improved.
