Abstract

PURPOSE:To prevnet variations in exothermic characteristics due to generation of heat, by provding a heat generation resistance layer consisting of polycrystalline silicone. CONSTITUTION:In order to form a heat generation resistance layer 13 with polycrystalline silicone, a substrate 1 is placed in an ordinary gas phase growth device by, for example, CVD method, which substrate 1 is provided thereon with a heat strage layer 2 only and with no heat generation resistance layer 13, electrodes 4, 5 and protective layer 6. Silane SiH4 is introduced into the growth device by using a carrier gas consisting of hydrogen or helium while maintaining the temperature of the substrate 1 at 700-1000 deg.C. The silane SiH4 is thermally decomposed to form a desired shape of heat generation resistance layer 13. The heat generation resistance layer 13 may be formed to a desired thickness and shape and to a predetermined resistance value by sputtering or evaporation. The exothermic characteristics never vary due to heat generated by the heat generation resistance layer 13 itself.
