Abstract: A metal lead, a semiconductor device and method of fabricating the same are disclosed, in which a first trench is formed simultaneously with a wiring layer trench, followed by the formation of a second trench in communication with the first trench.

This saves the use of two photomasks, leading to savings in production cost.
