Patent JP-S5846676-A (JP)
Title: Preparation of semiconductor device
Inventor: YONEDA TADANAKA
IPC: H01L29/72
Filed: 1981-09-11
Abstract: PURPOSE:To obtain a transistor which shows low leak current, low noise, high backward breakdown voltage and low base resistance by forming the base and emitter with ion implantation. CONSTITUTION:Crystal defects 34, 38 caused by ion implantation are formed within the emitter region 37 and the SiO2 film 30 on the emitter-base junction is formed by the heated oxide film. Accordingly, the emitter-base leak current is low and Si-SiO2 interface level density is also small. Since the graft base including impurity in high concentration is not in contact with the emitter region, a high backward breakdown voltage (BVRBO) can be obtained. In addition, since the graft base region 35 formed by deep diffusion is not in contact with the emitter region 37, the base width in the periphery of emitter region 37 does  not become wide and therefore hFE does not become low. Moreover, since the  graft base region is formed by the self-aligning method, distance between the  graft base region and emitter region becomes short and accordingly a base resistance (rbb') becomes small.

When the furnace is heated to the temperature of 1,000 deg.C, iron is employed as the material of a heating plate 2 but when the furnace is heated to a temperature higher than 1,000 deg.C, carbon and the like is employed. The heating plate 2 is constituted so as to be replaceable freely. According to this method, the furnace may be heated to a high temperature against which the furnace wall can withstand.
