Abstract:
A semiconductor device and a method of forming the semiconductor device is disclosed. A sacrificial film is used to pattern a contact to a semiconductor structure, such as a contact to a source/drain region of a transistor. The contact may include a tapered profile along an axis parallel to the gate electrode such that an outermost width of the contact decreases as the contact extends away from the source/drain region.
