发明名称 Gate CD trimming beyond photolithography
摘要 A semiconductor device is fabricated with a selected critical dimension. A gate dielectric layer is formed over a semiconductor body. A gate layer comprised of a conductive material, such as polysilicon, is formed over the gate dielectric layer. The gate layer is patterned to form a gate electrode having a first horizontal dimension. One or more growth-stripping operations are performed to reduce a critical dimension of the gate electrode to a second horizontal dimension, where the second horizontal dimension is less than the first horizontal dimension.
