摘要:
Complementary metal oxide semiconductor integrated circuits may be formed with NMOS and PMOS transistors having different gate dielectrics. The different gate dielectrics may be formed, for example, by a replacement process. The gate dielectrics may differ in material, thickness, or formation techniques, as a few examples.
