IPC: H01L29/84
Filed: 1990-06-30
Abstract: PURPOSE:To widen the selection range of a material for an object to be strained by a method wherein an amorphous silicon film is formed on the surface of the object to be strained, it is changed to polysilicon by executing a laser annealing operation and a strain gauge is formed. CONSTITUTION:An insulating layer 2 by silicon oxide is formed, by a P-CVD method, on the surface of a substrate 1 such as stainless steel or the like. An amorphous silicon film 3 is formed on the surface of the insulating film 2 by a P-CVD method using silane gas and at a substrate temperature of about 150 to 200 deg.C. This assembly is put into an electric furnace; and it is heat-treated at 450 deg.C for one hour to remove hydrogen. A part where a strain gauge 4 is to be formed is irradiated with an excimer laser; a laser annealing operation which has nothing to do with a substrate temperature is executed; and one part of the amorphous silicon thin-film 3 is changed to polysilicon 4'. An active gauge and a dummy gauge are installed in the part where the strain gauge 4 is formed in the same manner as conventional acceleration sensors of a cantilever piece. A patterning operation is executed so as to correspond to a prescribed formation position. Consequently, a semiconductor strain gauge can be formed at a low temperature.
