    Abstract: A method of forming a semiconductor device includes forming a channel layer on a substrate. A gate dielectric is deposited on the channel layer, and a mask is patterned on the gate dielectric. An exposed portion of the gate dielectric is removed to expose a first source/drain region and a second source/drain region of the channel layer. A first source/drain contact is formed on the first source/drain region and a second source/drain contact is formed on the second source/drain region. A cap layer is formed over the first source/drain contact and the second source/drain contact, and the mask is removed. Spacers are formed adjacent to sidewalls of the first source/drain contact and the second source/drain contact. An oxide region is formed in the cap layer and a carbon material is deposited on an exposed portion of the gate dielectric.
