Abstract: PURPOSE:To decrease leakage current and defect density of an oxidizing film on a polycrystalline silicon, by forming first polycrystalline silicon and further laminating second polycrystalline silicon which is smaller in the concentration of an impurity (phosphorus or arsenic or boron) added thereto than the first polycrystalline silicon. CONSTITUTION:A first polycrystalline silicon layer 3, which contains an impurity added thereto of phosphorus or arsenic or boron, is first formed, and a second polycrystalline silicon layer 4, which is at least smaller in the concentration of the added impurity of phosphorus or arsenic or boron than the first polycrystalline silicon layer 3, is next laminated below a semiconductor conductive layer 6. When the polycrystalline silicon layers are formed by such two steps, a grain boundary part of the first polycrystalline silicon layer 3 is unfitted, in their longitudinal positions, to the grain boundary part of the second polycrystalline silicon layer 4, and hence the degree of unevenness is relaxed. Hence, leakage current and defect density of an oxidizing film formed on the polycrystalline silicon layer can be decreased.
