Abstract:
A semiconductor device includes as a resistance element a first polycrystalline silicon and a second polycrystalline silicon containing impurities, such as boron, of the same kind and having different widths. The first polycrystalline silicon contains the impurities at a concentration C X . The second polycrystalline silicon has a width larger than a width of the first polycrystalline silicon and contains the impurities of the same kind at a concentration C Y  lower than the concentration C X . A sign of a temperature coefficient of resistance (TCR) of the first polycrystalline silicon changes at the concentration C X . A sign of a TCR of the second polycrystalline silicon changes at the concentration C Y .

Claim (Index 7):
A semiconductor device fabrication method comprising:\n acquiring a relationship between a concentration of first impurities and a temperature coefficient for a first polycrystalline silicon having a first width and a second polycrystalline silicon having a second width larger than the first width; setting, on the basis of the relationship, a first concentration of the first impurities in the first polycrystalline silicon and a second concentration of the first impurities in the second polycrystalline silicon; and forming the first polycrystalline silicon containing the first impurities at the first concentration and the second polycrystalline silicon containing the first impurities at the second concentration.
