Inventor: TOIDA HIKARI
IPC: H01L29/80
Filed: 1984-04-26
Abstract: PURPOSE:To prevent the deterioration of characteristics with a diffusion in the lateral direction of an impurity by lowering the concentration of the doping impurity between a source electrode and a gate electrode or between a drain electrode and the gate electrode in the vicinity of a gate. CONSTITUTION:Doping regions 32, 33 having high concentration are formed to a hihg-resistance substrate 31. These regions 32, 33 are shaped in such a manner that the concentration of a doping impurity is lowered in the vicinity of the end of a gate electrode 16 and impurity concentration is increased gradually toward a source electrode 15 and a drain electrode 17. Accordingly, at least either one of the concentration of the doping impurity between the electrode 15 and the electrode 16 or between the electrode 17 and the electrode 16 is lowered in the vicinity of the gate electrode, thus reducing the shifting of gate threshold voltage with a diffusion in the lateral direction of the impurity, the increase of parasitic capacitance and the decrease of gate reverse withstanding voltage. The concentration of the doping impurity is increased gradually toward the electrode 15 or the electrode 17 from a section in the vicinity of the electrode 16, thus lowering parasitic resistance.

Title: Semiconductor device
Inventor: ONO HAJIME
IPC: H01L29/06
Filed: 1983-05-16
Abstract: PURPOSE:To obtain dielectric resistance, which is close to one of a plane junction, by a planar type junction by relaxing field concentration and newly forming a region for equalizing an electric field. CONSTITUTION:A P type base region 12 is formed to an N type semiconductor substrate 11, and an N type emitter region is shaped in the region 12. A P type region 14 is formed as a region of the same conduction type as the region 12 while being brought into contact with at least one part of the region 12. Impurity concentration in the region 14 is determined to low impurity concentration so that the region 14 is depleted approximately when reverse breakdown voltage is applied between the region 12 and the substrate 11. The boundary line of the extent of a depletion layer 17 at that time is shown by a broken line 18. Consequently, when reverse breakdown voltage is applied between the region 12 and the substrate 11, the negative charges of the region 14 extremely reduce, and are depleted approximately. There are hardly charges even in a region 19 surrounded and shown by a dot-dash line, and the positive charges of the depletion layer 17 are also dispersed sporadically. Accordingly, dielectric resistance is increased because charges are not concentrated.
