Abstract: In a SiC-based MISFET and a manufacturing process thereof, after the introduction of an impurity, extremely-high-temperature activation annealing is required. Accordingly, it is difficult to frequently use a self-alignment process as performed in a silicon-based MISFET manufacturing process. This results in the problem that, to control the characteristics of a device, a high-accuracy alignment technique is indispensable. In accordance with the present invention, in a semiconductor device such as a SiC-based vertical power MISFET using a silicon-carbide-based semiconductor substrate and a manufacturing method thereof, a channel region, a source region, and a gate structure are formed in mutually self-aligned relation.

Abstract: In general, in a semiconductor active element such as a normally-off JFET based on SiC in which an impurity diffusion speed is significantly lower than in silicon, gate regions are formed through ion implantation into the side walls of trenches formed in source regions. However, to ensure the performance of the JFET, it is necessary to control the area between the gate regions thereof with high precision. Besides, there is such a problem that, since a heavily doped PN junction is formed by forming the gate regions in the source regions, an increase in junction current cannot be avoided. The present invention provides a normally-off power JFET and a manufacturing method thereof and forms the gate regions according to a multi-epitaxial method which repeats a process including epitaxial growth, ion implantation, and activation annealing a plurality of times.
