Abstract
Semiconductor devices and methods of forming the same include forming a first stack of nanosheets in a first region, the first stack of nanosheets including upper first nanosheets and lower first nanosheets. A second stack of nanosheets is formed in a second region, the second stack of nanosheets including upper second nanosheets and lower second nanosheets. A lower gate cut structure is formed between the lower first nanosheets and the lower second nanosheets. A gate stack is formed on the first and second stack of nanosheets after forming the lower gate cut structure. An upper gate cut structure is formed after forming the gate stack.
