ABSTRACT:
In an oscillation circuit consisting of an amplification circuit portion composed of transistors of input/output circuit basic cells of a gate array disposed on a semiconductor pellet and an oscillator disposed outside the semiconductor pellet, the amplification circuit portion consists of transistors for an output circuit of the input/output buffer circuit basic cells. The dielectric breakdown characteristics of the amplification circuit portion of the oscillation circuit can be improved because the structure of the transistor for the output circuit is more highly resistant to dielectric breakdown than the structure of the transistor for the input circuit.
