A P type semiconductor layer is formed on an N type semiconductor layer by vapour epitaxial growth technique, an insulating film is formed on the P type semiconductor layer and a grid shape first opening is provided through the insulating film. Then, phosphorus is diffused into the P type semiconductor layer through the grid shape opening to form a first N type region extending through the semiconductor layer to reach the N type semiconductor layer. Then, second openings are formed through respective sections of the insulating film divided by and surrounded by the grid shape first opening and boron is diffused through the first and second openings to form first and second P type regions in the grid shape first N type region and the P type semiconductor layer, respectively. Finally, third openings are formed through respective portions of the insulating film and phosphorus is diffused into the P type semiconductor layer through the third openings to form second N type regions thereby forming an integrated injection logic semiconductor device including a lateral PNP transistor and a vertical NPN transistor.

A proposed non-volatile semiconductor memory and a method of manufacturing the same are directed to performing stable and highly reliable operations. First, grooves are formed in a p-type silicon semiconductor substrate, and impurity diffusion layers are formed on the bottom surfaces of the grooves. A gate insulating film is then formed on the p-type silicon semiconductor substrate. This gate insulating film has a three-layer structure in which a first insulating film made of a silicon oxide film, a charge capturing film made of a silicon nitride film, and a second insulating film made of a silicon oxide film, are laminated in this order. A gate electrode is then formed on the gate insulating film. A convexity formed by the grooves serves as the channel region of the non-volatile semiconductor memory. Even if the device size is reduced, an effective channel length can be secured in this non-volatile semiconductor memory. Thus, excellent stability and reliability can be achieved.

This invention discloses a semiconductor integrated circuit in which an input protecting circuit and an inner circuit are formed on a single semiconductor substrate and a MOS transistor of the inner circuit is formed by mask-alignment. The source and drain regions of the MOS transistor of the input protecting circuit are formed by self-alignment, so that the impurity concentration of the source and drain regions is increased and the diffusion resistance thereof is reduced, thereby increasing the junction breakdown power caused by a drain current. In addition, the radii of curvature of the junction curved surface portions of the source and drain regions of the MOS transistor of the input protecting circuit are increased so as to reduce the electric field intensity at the junction curved surface portions, thereby improving the junction breakdown withstand characteristics.
