Abstract: PURPOSE:To eliminate the voltage dependence of resistor element by providing a conductive poly Si layer through an insulating film of required film thick on a resistor element wherein each high potential difference side for the substrate is connected. CONSTITUTION:A p-type resistor element 3 is formed on the n epitaxial layer 2 of a p-type Si substrate 1 and p<+> electrode connection layers 4, 5 and an n<+> connection layer 6 are provided. A conductive poly Si layer 7 is provided through an SiO2 film 8 of about 5,000Angstrom  thick and connected to a terminal c on a p<+>-layer 4. A terminal d on a p<+>-layer 5 is connected to an n<+>-layer 6. If a negative potential is applied to the terminal c and a positive potential to the terminal d, holes will be stored near the terminal d and more holes will be stored as the potential difference between the terminal c and the epitaxial layer increases. Therefore, the resistance becmes small and a depletion layer near the terminal c expands with potential difference and the whole resistance value will almost remain unchanged even if the resistance increases. In this way, the voltage dependence of the resistor element will be minimized.
