Last updated:
Abstract:
An embodiment of the invention may include a Vertical Field Effect Transistor (VFET) structure, and method of making that structure, having a first VFET and a second VFET. The first VFET may include a single liner between a first source/drain epi and a contact. The second VFET may include two liners between a second source/drain epi and a contact. This may enable proper contact liner matching for differing VFET devices.
