PURPOSE:To control polarity switching by turning on a state between a power supply and an output by depressed ion implantation, turning off a state between earth and the output, or turning off the state between the power supply and the output and turning on the state between the earth and the output. CONSTITUTION:As depressed ion implantation is performed only for transistors Q1, Q2, the transistors Q1, Q2 are turned on, and Q2, Q1 are off, so that corresponding potentials at a node N1 are H, L levels and potentials an N2 are L, H levels. Herein, once a signal IN1 is inputted into a node N3, a transistor Q6 is turned on when ion implantation is conducted only for the transistor Q1, and hence a signal OUT1 of the same phase as that of the signal IN1 is issued from a node N4. Reversely, when the ion implantation is conducted only for the transistor Q2, a transistor Q5 is turned on and the signal OUT1 becomes a signal reverse to the signal IN1 in phase. Hereby, a two polarity output signal can be yielded from one signal by controlling depressed ion implantation. |
