IPC: H01L21/822
Filed: 1987-09-15
Granted: 1996-07-25
Abstract: A latch-up protection circuit for an integrated circuit using complementary MOS circuit technology has a substrate bias generator that applies a negative substrate bias to a semiconductor substrate having a p-conductive material into which a well-shaped semiconductor zone of n-conductive material is inserted. In order to avoid latch-up effects in the integrated circuit, an electronic protection circuit interrupts the capacitive charging currents of a capacitor in the substrate depending on the potential of the semiconductor substrate which is taken at a doped substrate bias terminal. The electronic protection circuit disconnects a capacitor bias generator from the capacitor when a voltage on the substrate bias terminal is greater than a difference between a reference potential and a threshold voltage of a first transistor in the electronic protection circuit. The electronic protection circuit connects the capacitive bias generator to the capacitor when a voltage on the substrate bias terminal is lower than the difference. No quiescent current flows through the electronic protection circuit during normal operation of the integrated circuit.
