    摘要: A semiconductor apparatus on which a MOS transistor having an elevated source and drain structure is formed is arranged to have a gate electrode which is formed on the surface of a silicon substrate through an insulating film. An elevated source film and an elevated drain film each having at least a surface portion constituted by a metal silicide film, being conductive and elevated over the surface of the silicon substrate are formed on a source region and a drain region on the surface of the silicon substrate. Thus, a MOS transistor having a structure in which the surfaces of the source region and the drain region are elevated over the surface of the silicon substrate is formed. A first gate-side-wall insulating film is formed on the side wall of the gate electrode of the MOS transistor and having a bottom surface formed apart from the surface of the silicon substrate. A second gate-side-wall insulating film is formed between the first gate-side-wall insulating film and the gate electrode and on the bottom surface of the first gate-side-wall insulating film. The portion formed on the bottom surface exists in an inner bottom surface portion of the bottom surface of the first gate-sidewall insulating film adjacent to the gate electrode. The elevated source film and the elevated drain film are free from any facet in portions made contact with the first gate-side-wall insulating film.

    摘要: A method of manufacturing a semiconductor device, which comprises the steps of forming a solid phase diffusion source containing a conductive impurity on a surface of a semiconductor substrate, said impurity serving to enable said semiconductor substrate to exhibit a p-type or n-type conductivity, allowing said solid phase diffusion source to contain a diffusion control substance serving to reduce or oxidize said conductive impurity upon heating so as to change the diffusion coefficient of the conductive impurity contained in the solid phase diffusion source, and thermally diffusing the conductive impurity from the solid phase diffusion source into the semiconductor substrate.

    摘要: According to the present invention, a method of manufacturing a semiconductor apparatus is provided which comprises the steps of (a) depositing a boron layer on a silicon substrate, and (b) thermally diffusing boron from said boron layer into said silicon substrate. The present invention, which is characteristically based on the solid phase diffusion process, enables even a thin layer to be deposited. Further, unlike the ion implantation process, the present invention enables an impurity to be uniformly diffused even into an inclined plane. Unlike the case where boron-containing glass is used as a diffusion source, the invention enables a sufficient amount of boron to be diffused even at a temperature lower than 1000.degree. C.
