In one example, an electronic device includes a semiconductor substrate, a first fin coupled with the semiconductor substrate, the first fin comprising a first source region and a first drain region, and a first gate structure of a recessed channel array transistor (RCAT) formed in a first gate region disposed between the first source region and the first drain region, wherein the first gate structure is formed by removing a sacrificial gate structure to expose the first fin in the first gate region, recessing a channel structure into the first fin, and forming the first gate structure on the recessed channel structure.

    摘要: In general, in one aspect, a method includes forming a semiconductor substrate having N-diffusion and P-diffusion regions. A gate stack is formed over the semiconductor substrate. A gate electrode hard mask is formed over the gate stack. The gate electrode hard mask is augmented around pass gate transistors with a spacer material. The gate stack is etched using the augmented gate electrode hard mask to form the gate electrodes. The gate electrodes around the pass gate have a greater length than other gate electrodes.
