Patent JP-H0242757-A (JP)
Title: Semiconductor device
Inventor: KOGA TAKESHI
IPC: H01L27/11
Filed: 1988-08-02
Abstract: PURPOSE:To suppress an irregularity in a resistance value of a high-resistance element by a variation during a production process by a method wherein an interlayer insulating film between the high-resistance element composed of polycrystalline silicon and a wiring part by polysilicon or a metal is made thin and a voltage applied to the wiring part is made variable. CONSTITUTION:A film thickness of a silicon oxide film as an insulating film between a high-resistance element and a wiring part 17 or 18 is made thin to be 1000Angstrom  or lower. In this case, when a negative voltage is applied to the wiring part 17 at the upper part of the high-resistance element 2, a resistance value of the high-resistance element 2 is increased; in addition, when a potential of the wiring part 18 at the upper part of a high-resistance element 3 is controlled in a direction of a more positive voltage, a current value which can flow in the high-resistance element 3 can be increased. Since the resistance value of the high-resistance element can be selected and controlled freely in this manner by changing the voltage to be applied to the wiring part, it is possible to suppress an irregularity in a high-resistance value by an irregularity or the like during a production process.
