Abstract

A signal generating and switching apparatus and a method thereof are provided. According to a simple layout technique, the signal switching apparatus is formed in each layer of a plurality of metal layers in an integrated circuit. When there is a need to correct any one of the plurality of conductive layers in the integrated circuit, the changing of the signal switching apparatus in that conductive layer can be achieved by changing mask patterns of the conductive layer. As a result, the transmission path of signals in the conductive layer is changed, and the purpose to change output logic signals is achieved. Therefore, there is no need to change additional conductive layers, thereby significantly reducing the correcting cost of the integrated circuit.
