Patent number: 6071781Abstract: There is provided a method of fabricating a lateral MOS transistor, including the steps of (a) forming a gate oxide film on a semiconductor substrate, (b) forming a gate electrode on the gate oxide film, (c) forming a mask covering one of regions of the semiconductor substrate adjacent to the gate electrode, (d) ion-implanting the semiconductor substrate with impurities having a first electrical conductivity as the semiconductor substrate is being rotated around the gate electrode, at an angle relative to the semiconductor substrate to form a channel region in an uncovered region, (e) ion-implanting the semiconductor substrate with impurities having a second electrical conductivity around the gate electrode in self-aligned manner to thereby form source and drain regions.

Patent number: 5814542Abstract: A fabrication method of a semiconductor device that makes it possible to reduce the number of necessary process steps. After an insulating layer is formed on a semiconductor substructure, a polysilicon layer is formed on the insulating layer. Then, dopant atoms are implanted into the polysilicon layer so that the peak depth of the distribution of the implanted dopant atoms is located at approximately the middle level of the polysilicon layer. The implanted polysilicon layer is subjected to a heat-treatment to thereby form a dielectric region at the middle level of the polysilicon layer due to reaction of the implanted dopant atoms with silicon atoms existing in the polysilicon layer. The remaining lower and upper parts of the polysilicon layer form lower and upper polysilicon regions, respectively. Subsequently, the implanted and heat-treated polysilicon layer is patterned to have a predetermined shape. As the dopant atom to be implanted, oxygen (O) and/or nitrogen (N) is preferably used.Type: GrantFiled: January 9, 1997Date of Patent: September 29, 1998Assignee: NEC CorporationInventor: Chika Nakajima
