Abstract

A method of fabricating a semiconductor structure is disclosed, in which a pad above a connecting section and metal structures above a functional section are formed from the same metal layer. This design enables the simultaneous formation of the pad and the metal structures by forming a single metal layer and performing thereon a selective etching process, thereby leading to the advantages of process simplification, throughput improvement and cost reduction.
