摘要： The invention provides an n-channel MOS field effect transistor with an improved anti-radioactivity. Such transistor includes a p-type silicon substrate. An isolation oxide film is selectively formed on a surface of the p-type silicon substrate. Source and drain diffusion layers of n+-type are formed on first opposite sides of a channel region in the p-type silicon substrate. A gate made of polycrystalline silicon is formed over the channel region through a gate oxide film. Leak guard diffusion layers of p-type are formed on second opposite sides of the channel region in the p-type silicon substrate. The p-type leak guard diffusion layer has a junction surface to the isolation oxide film. The junction surface of the p-type leak guard diffusion layer and the isolation oxide film exists up to a level which is deeper than a depth of the n+-type source and drain diffusion layers.

摘要： The invention provides an n-channel MOS field effect transistor with an anti-radioactivity. The transistor includes leak guard boron diffusion layers, each of which has a junction surface to an isolation oxide film. The junction surface exists up to a deeper level than a predetermined depth corresponding to a junction surface of n-type source and drain diffusion layers and a p-type silicon substrate. Such leak guard boron diffusion layer is formed by ion-implantation of boron through a gate oxide film, after a formation of the gate oxide film. Such leak guard boron diffusion layers have a higher impurity concentration. The existence of the leak guard boron diffusion layers suppresses a leak to be generated by radiation damages of silicon oxide film such as the gate oxide film and the isolation oxide film.
