Abstract:
A tapered metal nitride structure having a gentle sloping (i.e., tapered) sidewall is provided that includes an oxygen rich metal nitride portion located between each metal nitride portion of a stack of metal nitride portions. The structure is formed by incorporating/introducing oxygen into an upper portion of a first metal nitride layer to form an oxygen rich metal nitride surface layer. A second nitride is then formed atop the oxygen rich metal nitride surface layer. The steps of oxygen incorporation/addition and nitride layer formation may be repeated any number of times. An etch mask is then provided and thereafter a sputter etch is performed to provide the tapered metal nitride structure. The tapered metal nitride structure may be used as an electrode in a semiconductor device.

Claim (Index 10):
The method of  claim 1 , wherein the first metal nitride layer is composed of a transition metal selected from Groups 4, 5 and 6 of the Periodic Table of Elements.
