Title: Semiconductor device
Inventor: TOMIZAWA HISAO
IPC: H01L23/36
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To improve an yield in manufacturing, by protecting a pedestal of a semiconductor device from solidifying in a slanted state and prevent a deterioration in characteristics under severe environmental and temperature conditions. SOLUTION: A semiconductor device has a supporting body 1, a flat rectangular pedestal 2 fixed with solder material 6 on the supporting body 1, and a diode chip 3 fixed on the pedestal 2. The pedestal 2 has a slanted part 8 at each edge part of its main face to be fixed to the supporting body 1, while a cross area of the slanted part 8 is reduced gradually as it goes near to the supporting body 1. At the same time, the pedestal 2 has a groove part 9 formed at each corner and extended along diagonal lines to the center of the pedestal 2. A gap between the pedestal 2 and the supporting body 1, including the groove part 9, is filled with the solder material 6. The slanted part 8 is covered with the solder material 6.  Since the groove part 9 at four corners of the pedestal 2 is slanted upward in the outer direction, the surplus solder melted between the pedestal 2 and the electrode moves by its weight outward along the lower surface (one main surface) of the pedestal 2.

Filed: 1985-02-25
Abstract: PURPOSE:To alleviate the production and adherence of a foreign material due to the discharge of reaction gas by reacting O2 gas with reactive gas absorbed to the inner wall of a reaction furnace before conveying a wafer after feeding N2 gas. CONSTITUTION:Semiconductor wafers 5 are aligned on a wafer table 4 in a reaction furnace 1. A heater 10 is energized to heat the wafers 5. Purging N2 gas is fed from a purging gas feeding tube 9 into the furnace, and reaction gas is fed from a reaction gas feed tube 8 into the furnace. Then, N2 gas is fed from the tube 9 into the furnace, and when the reaction gas is purged, the gas absorbed to the inner wall of the furnace remains. When O2 gas is fed from the tube 9, the reaction gas absorbed to the inner wall of the furnace is reacted with the O2 gas to form a foreign material. When N2 gas is fed from the tube 9, fine materials not adhered to the furnace wall of the foreign materials are purged together with the O2 gas. Thus, the projection and adher ence of the foreign material due to the discharge of the reaction gas can be alleviated.
