    摘要: Multi-stage preheat high-temperature anneal processes after the deposition of the gate dielectric layer(s) reduce the number of interfacial sites and improve the negative bias temperature instability (NTBI) performance of a p-type metal-oxide-semiconductor transistor (PMOS). The gate dielectric layers may include an interfacial oxide layer and a high-k dielectric layer. The multi-stage preheat is designed to reduce dopant deactivation and to improve inter-mixing between the interfacial oxide layer and the high-k dielectric layer. The high-temperature anneal is used to reduce the number of interfacial sites at the interface between the silicon substrate and the interfacial oxide layer.

    摘要: A method for forming an STI structure is provided. In one embodiment, a trench is formed in a substrate, the trench having a first sidewall and a second sidewall opposite the first sidewall, the sidewalls extending down to a bottom portion of the trench. An insulating material is deposited to line the surfaces of the sidewalls and the bottom portion. The insulating material proximate the top portions and the bottom portion of the trench are thereafter etched back. The insulating material is deposited to line the inside surfaces of the trench at a rate sufficient to allow a first protruding insulating material deposited on the first sidewall and a second protruding insulating material deposited on the second sidewall to approach theretogether. The steps of etching back and depositing are repeated to have the first and second protruding materials abut, thereby forming a void near the bottom of the trench.
