Title: Mis semiconductor device and manufacture thereof
Inventor: OOE KIKUYO
IPC: H01L21/76
Filed: 1987-10-20
Abstract: PURPOSE:To improve an excess sidewall current and back gate bias effect by providing the same conductivity type high concentration diffused layer as that of a substrate on a substrate region of part of the top of the side face of the substrate in contact with a groove and in contact with the surface of the substrate without channel width by controlling the width of a sidewall insulating film. CONSTITUTION:A protrusion type insulating film 4 is formed on one semiconductor substrate 1, and with the film as a mask the same conductivity type impurity as that of the substrate 1 is implanted. Then, sidewall insulating films 7 are formed at both sidewalls of the protrusion of the insulating film, and with the films 4 and 7 as masks a groove 8 is formed by etching. Accordingly, the same conductivity type high concentration diffused layer as that of the substrate is provided only on a substrate region in contact with the part of the top of the side face of the substrate in contact with the groove and in contact with the substrate surface without channel width by controlling the width of the insulating film 7 with the groove type insulating isolating layer of necessary depth for the one substrate. Thus, its back gate bias effect can be suppressed, and the width of the sidewall insulating film is controlled, thereby forming the same conductivity type high concentration layer as that of the substrate only on the sidewall even if the channel width is small, and suppressing an excess sidewall current.

CONSTITUTION:In the case of a GaAs crystal wafer wherein the miller indices (100) of the main plane is regarded as optimum for forming a semiconductor element, at first, a facet is formed in the perpendicular direction against a shifted plane at the range of 10-15 deg. clockwise or counter clockwise from the (011) plane at the center of the (100) axis in the state of a crystal ingot. A wafer is cut from the crystal ingot to make a plane of slightly inclining from the plane of miller indices (100), e.g., approx. 7 deg. the main plane. The perpendicular direction to the surface cut from the crystal ingot is a direction wherein atoms are dense. Consequently, even if the GaAs crystal wafer is placed horizontally and an ion is implanted from the perpendicular direction to he main plane, the channeling phenomenon is not generated.
