    摘要: A method of forming a silicided gate of a field effect transistor on a substrate having active regions is provided. The method includes the following steps: (a) forming a silicide in at least a first portion of a gate; (b) after step (a), depositing a metal over the active regions and said gate; and (c) annealing to cause the metal to react to form silicide in the active regions, wherein the thickness of said gate silicide is greater than the thickness of said silicide in said active regions.

    摘要: A process for reducing the thermal budget and enhancing stability in the thermal budget of a metal salicide process used in the formation of metal salicides on substrates, thus eliminating or reducing salicide spiking and junction leakage in microelectronic devices fabricated on the substrates. According to a typical embodiment, a substrate is cooled to a sub-processing temperature which is lower than the metal deposition processing temperature and the salicide-forming metal is deposited onto the reduced-temperature substrate.
