A programmable power-failure-detection circuit in an integrated circuit is provided that permits programmable selection of operating modes that either monitor a power supply of the integrated circuit or provide reduced power consumption from the power supply by disabling the monitoring of the power supply. The projecting includes projecting the insulating member from the upper surface of the semiconductor substrate by removing an upper layer portion of the semiconductor substrate. Exchangeable members are available for variability in height and offset angle beyond a specified range.
