Disclosed is a method of executing an electrical function, such as a fusing operation, by activation through a chip embedded photodiode through spectrally selected external light activation, and corresponding structure and circuit. The present invention is based on having incident light with specific intensity/wave length characteristics, in conjunction with additional circuit elements to an integrated circuit, perform the implementation of repairs, i.e., replacing failing circuit elements with redundant ones for yield and/or reliability. Also to perform disconnection of ESD protection device from input pad once the packaged chip is placed in system. No additional pins on the package are necessary.
