A second polysilicon layer which is used as polysilicon resistor is exactly over a first polysilicon layer. The double polysilicon layer is utilized to reduced a stand-by current. A electric field is generated between the two layers caused by applying different voltage to the two polysilicon layer respectively, and the carriers in the second polysilicon layer will be repeled to form a depletion region, which will increase the resistance of the second polysilicon layer. Therefore, the stand-by current (Isb) will be reduced.
