Wiring for semiconductor device and method for forming the same

摘要

Wiring for a semiconductor device which is suitable for high density device packing, and a method for forming the same, are disclosed. The wiring includes: impurity regions formed in a substrate on both sides of an insulated gate electrode; a first conduction layer formed on the impurity regions; and a second conduction layer formed in contact with the first conduction layer on one side of the gate electrode. The method includes the steps of: forming impurity regions in a substrate on both sides of an insulated gate electrode; forming a first conduction layer on the impurity regions; and forming a second conduction layer in contact on one side of the gate electrode with the first conduction layer.
