摘要:
In general, in one aspect, a method includes forming N-diffusion and P-diffusion fins in a semiconductor substrate. A P-diffusion gate layer is formed over the semiconductor substrate and removed from the N-diffusion fins. A pass-gate N-diffusion gate layer is formed over the semiconductor substrate and removed from the P-diffusion fins and pull-down N-diffusion fins. A pull-down N-diffusion layer is formed over the semiconductor substrate.
