Title: Production of semiconductor device
Inventor: MIHARA KIYOHIKO
IPC: H01L21/22
Filed: 1978-03-24
Abstract: PURPOSE: To realize simultaneously a high dielectric strength, a large capacity, and a high-speed production by diffusing gold after diffusing B into the p layer of pn junction with a depth over 15μm over 5×10 19 /cc.  
     CONSTITUTION: After SiO 2  mask 2 is used to form selectively a n layer on one main face of a pnp-structure Si substance, the SiO 2  mask is use again to accumulate B on the other main face. P +  layer is formed by driving-in with the processing at 1250°C for several hours, and a surface area of 5×10 19 /cc and a depth over 15μm is given to this layer. Next, the mask is removed to evaporate gold 5, and gold 5 is diffused at a prescribed temperature, and Si substance 1 is fixed to electrode support plate 4 with Al soldering material 3 by alloying. Thus, since distortion is generated inside Si by high-density B to increase a dislocation density and facilitate gold diffusion, the turn-off time is effectively shortened by a small amount of gold diffusion, and the forward voltage drop and the leakage current are reduced, and the ohmic contact between support plate 4 and substance 1 becomes well, so that a high-performance device can be obtained.
