SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device with an increasing speed while assuring the improvement of yield of products and reliability. SOLUTION: The semiconductor integrated circuit device having a main circuit comprising MOSFET and a substrate bias circuit for supplying positive bias voltage to a semiconductor region in which the MOSFET is formed, is provided with a current limiting circuit for limiting current being supplied to the semiconductor region in response to a substrate current flowing between the semiconductor region where the MOSFET is formed and the source.
