Abstract: A method of simulating a 3D feature profile by using a scanning electron microscope (SEM) image includes providing an SEM image. The SEM image includes a feature pattern within a material layer. The feature pattern includes an inner edge and an outer edge. The outer edge surrounds the inner edge. Then, the positions of the inner edge and the outer edge of the feature pattern are identified. Latter, a side edge region is defined based on the positions of the inner edge and the outer edge. Subsequently, a side edge model is generated automatically to simulate a profile of the feature pattern in the side edge region. Finally, a 3D feature profile is automatically output based on the position of the inner edge, the position of the outer edge, the thickness of the material layer and the side edge profile.

Abstract: A method of forming a semiconductor device is disclosed. A substrate having a first device region and a second device region is provided. A metal nitride barrier layer is formed to cover the first device region and the second device region. A titanium layer is deposited on the metal nitride barrier layer. The titanium layer is selectively removed from the second device region, thereby exposing the metal nitride barrier layer in the second device region. The titanium layer in the first device region is transformed into a titanium nitride layer. The titanium nitride layer is a work function layer on the first device region.
