    摘要: A method of manufacturing a FinFET semiconductor device is provided, wherein the semiconductor fins are formed in a parallel arrangement which intersects the gates arranged in parallel. The polycrystalline silicon layer is deposited and then converted into a single crystal silicon layer such that the single crystal silicon layer and the semiconductor fins are integrated in essence, i.e., the source/drain region in the semiconductor fins is raised and the top area of the semiconductor fins is extended. Subsequently, the single crystal silicon layer above the top of the semiconductor fins is converted into a metal silicide so as to form a source/drain region contact. The source/drain region contact in the present invention has a larger area than that in a conventional FinFET, which decreases the contact resistance and facilitates the formation of a self-aligned metal plug in the follow-up process.

    摘要: A method for manufacturing a semiconductor device is disclosed, comprising: providing a substrate, a gate region on the substrate and a semiconductor region at both sides of the gate region; forming sacrificial spacers, which cover a portion of the semiconductor region, on sidewalls of the gate region; forming a metal layer on a portion of the semiconductor region outside the sacrificial spacers and on the gate region; removing the sacrificial spacers; performing annealing so that the metal layer reacts with the semiconductor region to form a metal-semiconductor compound layer on the semiconductor region; and removing unreacted metal layer. By separating the metal layer from the channel and the gate region of the device with the thickness of the sacrificial spacers, the effect of metal layer diffusion on the channel and the gate region is reduced and performance of the device is improved.
