Abstract: PROBLEM TO BE SOLVED: To enable formation of a low or high resistance without substantially no change of an existing process by utilizing a polycrystalline silicon layer of a bipolar semiconductor device. SOLUTION: A base region 2 of one conduction type is formed in a semiconductor substrate 1 of a conduction type opposite to the one conduction type, an emitter region 3 of the same conduction type as the substrate 1 is formed in the base region 2, and a polycrystalline silicon layer is formed on a surface of the substrate 1. First non-doped polycrystalline silicon layer is formed on the substrate 1. Thereafter a low concentration of impurities are doped into the non-doped polycrystalline silicon layer to form a high-resistance, low- concentration doped polycrystalline layer 5B.  Further, upon impurity diffusion to form the emitter region 3, impurities are selectively diffused into the low- concentration doped polycrystalline silicon layer 5B from the same diffusion source to convert part of the low-concentration doped polycrystalline silicon layer to a low-resistance, high-concentration doped polycrystalline silicon layer.
