Abstract:
1. A thin film resistor formed on a semiconductor substrate having a gate structure disposed thereover, said thin film resistor comprising: a layer of dielectric material overlying said gate structure; and a titanium oxynitride structure having a first portion that extends within an opening in said layer of dielectric material, said first portion of said titanium oxynitride structure overlying a conductive layer of said gate structure such that said titanium oxynitride structure is electrically coupled to said gate structure, said titanium oxynitride structure having a second portion that overlies said layer of dielectric material, and said titanium oxynitride structure including a third portion that extends along sidewalls of said opening in said layer of dielectric material so as to partially fill said opening in said layer of dielectric material, said third portion extending vertically between said first portion and said second portion.
