Abstract
A device and method of manufacture for a low capacitance overvoltage protection device. This is accomplished through the use of PiN diodes to shunt overvoltage away from internal circuit elements. PiN diodes are useful because they exhibit a low capacitance in reverse bias mode. Radio frequency integrated circuits and other integrated circuits operated at high frequency are sensitive to capacitance. This invention protects against circuit damage due to overvoltage events while keeping capacitance low through the use of PiN diodes.
