Abstract
An electronic timepiece having a quartz crystal oscillator for producing a time standard signal, a frequency divider, and a display device. A CMOS integrated circuit on an N-type substrate is provided for the elements. A first aluminum lead and a second aluminum lead are provided on the CMOS integrated circuit. The first aluminum lead is provided on the CMOS integrated circuit to connect the high potential side of voltage supply to the N-type substrate. The second aluminum lead is provided on the CMOS integrated circuit for supplying the voltage to a logic circuit in the CMOS integrated circuit. A resistor is provided between the second aluminum lead and high potential side of the voltage supply for preventing the latch-up of the CMOS integrated circuit.
