Title: Manufacture of semiconductor device
Inventor: HATAISHI OSAMU
IPC: H01L21/225
Filed: 1980-12-25
Abstract: PURPOSE:To prevent breakage of interconnections by controlling permeation of silicon atoms into aluminum metallization layers by a method of adding phosphorus in a polysilicon layers at wiring pads on the base. CONSTITUTION:A P type layer is produced on a silicon substrate by boron diffusion, and openings are then provided selectively on an SiO2 12 to deposit a polysilicon layer 13 of approximately 500Angstrom  thick and a PSG 14 of approximately 0.5mum thick. Treatment in N2 gas is carried out at 800 deg.C for about 30min and diffusion of phosphorus is made into the layer 13. After this, a layer 14A is formed by removing the PSG14 selectively to leave a region for forming the emitter. Treatment in N2 gas is made at 1,150 deg.C for 100 seconds and a shallow emitter layer 15 is produced by diffusion of phosphorus into a P type base 11 through the layer 14A. Next, the layer 14A is removed by HF etching, and a layer of aluminum is evaporated on the surface to form aluminum interconnections 16A, 16B by patterning using a resist coating and H3PO4 based solution. The process is completed after etching of the polysilicon layer 13 using the aluminum metallization layers as a mask. Such a construction allows prevention of breakage of aluminum interconnections because no serious separated deposit can be formed if silicon atoms permeate the aluminum metallization layers. Arsenic glass films are also effective.
