Abstract

1380143 Carrier lifetime in integrated circuits COMMISSARIAT A L'ENERGIE ATOMIQUE 9 March 1972 [9 March 1971] 11147/72 Heading H1K Silicon islands insulated from the substrate in which they are formed are diffused with a metal, leading to reduced charge carrier lifetime. In the part-structure shown an NPN transistor is formed by diffusions through an apertured silica masking layer 5 and the top surface is then coated with platinum by cathode sputtering and the structure then heated at 500‹ C. for up to 1 hour to form platinum silicide 12 in the contact apertures. The remaining free platinum is etched away with aqua regia and the structure heated at 950-1000‹ C. for a few minutes to diffuse platinum throughout the island. A ontact metal such as molybdenum, gold, titanium, platinum, or aluminium is then applied to the silicide areas. Beam leads may be formed by successive deposition on the silicide and silica of titanium, platinum, gold, and solder. The structure may be bonded by its beam leads to a ceramic substrate.
