摘要： A substrate includes a first doped region having a first type dopant, and a second doped region having a second type dopant and adjacent to the first doped region. A stack is formed that includes first layers and second layers alternating with each other. The first and second layers each have a first and second semiconductor material, respectively. The second semiconductor material is different than the first semiconductor material. A mask element is formed that has an opening in a channel region over the second doped region. A top portion of the stack not covered by the mask element is recessed. The stack is then processed to form a first and a second transistors. The first transistor has a first number of first layers. The second transistor has a second number of first layers. The first number is greater than the second number.
