Abstract
The invention discloses a semiconductor device and a manufacturing method thereof. After a groove is formed through etching a semiconductor substrate in a source/drain electrode area, a backing layer is formed through use of chemical vapor deposition and etched so as to form diffusion impervious layers, which are identical with the semiconductor substrate in conduction type and have a higher impurity concentration than the semiconductor substrate, at the two side walls of the groove and source/drain electrode areas, which have an opposite conduction type with the diffusion impervious layers, are continued to be formed at the internal and external edges of the groove. Therefore, because the diffusion impervious layers which have the opposite conduction type with the source/drain electrode areas are arranged between the source/drain electrode areas and impurities which diffuse from the source/drain electrode areas to a channel region transversely are neutralized so that increase of thicknesses of grid side walls is not required and the volume of the whole device is reduced and a serial-connection resistance between source/drain electrodes is reduced.
