摘要: An integrated circuit device and method for manufacturing an integrated circuit device is disclosed. The integrated circuit device comprises a core device and an input/output circuit. Each of the core device and input/output circuit includes a PMOS structure and an NMOS structure. Each of the PMOS includes a p-type metallic work function layer over a high-k dielectric layer, and each of the NMOS structure includes an n-type metallic work function layer over a high-k dielectric layer. There is an oxide layer under the high-k dielectric layer in the input/output circuit.
