Abstract

PURPOSE: To generate a potential of the opposite polarity to a power voltage in an IC with good reproducibility by providing two reverse conduction type regions to the surface of a one conduction type semiconductor substrate and by forming a series circuit of a capacitor and diode between those regions.
CONSTITUTION: On the surface of P-type semiconductor substrate 101, thick insulating substance 102 and N-type regions 103 and 104 are formed. Next, insulating substance 105 is provided with region 103 held at one voltage of the capacitor and other electrode 106 of the capacitor is formed of metal or a high-density semiconductor. Electrode 106 is connected to P-type region 107 provided to region 104. In this constitution, terminal 110 is grounded and terminal 108 is applied to a positive square pulse, so that when the potential reaches positive value V0, the potential at terminal 109 will becomes minus by contact potential Vin of the p-n junction of the diode formed between regions 107 and 104. Next, when the potential at terminal 108 decreases down to the earth potential, the potential at terminal 109 becomes minus by |Vin|+V0. In this way, a negative square pulse is generated at terminal 109. In addition, either conduction type of each region can be used.
