Abstract
Aspects of the present disclosure provide a semiconductor structure. For example, the semiconductor structure can include a lower channel structure, an upper channel structure formed vertically over the lower channel, a first transistor device including lower and upper gates formed around a first portion of the lower and upper channel structures, respectively, and a separation layer formed between and separating the lower and upper gates, and a second transistor device including a common gate formed around a second portion of the lower and upper channel structures. The first portion of the lower channel structure is equal to the first portion of the upper channel structure in width, and has a first width less than a second width of the second portion of the lower channel structure.
