PROBLEM TO BE SOLVED: To provide a semiconductor device which can carry out signal switch option only in a required layer for circuit correction. SOLUTION: Signal switch option can be switched in an arbitrary layer by having a means for releasing from a first signal in a plurality of arbitrary layers, and a means for short-circuiting to a second signal in a plurality of arbitrary layers. The switch option mechanism has a pad region which is formed in each layer and arranged in a vertical direction and a contact hole formed between the pad regions. A contact hole in pad regions of one layer or wiring layers is in its open state, and a layer which requires mask correction can be minimized by attaining connection by short-circuiting a pad or a contact hole in its open state in a layer to be corrected.
