Abstract
PURPOSE:To obtain the MISFET which is highly densed in the direction of height for the subject semiconductor device by a method wherein the surface of a P type Si substrate and a gate electrode, having a delta-shaped section, is formed at the end face of the substrate utilizing the stepping of a convexed section. CONSTITUTION:A field oxide layer 2 is provided on the P type Si substrate 1 and an N<+> type region 3, having an almost vertical end face, is selectively formed. An insulating film 4 is covered on the above, an aperture 41 is selectively provided and a P layer 5 of uniform thickness is formed. When a resist mask is provided and the P layer 5 is removed by performing a reactive etching without performing sidewise and taper etching, a delta-shaped layer 6 and electrodes 7 and 9 are formed on the side face 8 of the region 3. Besides, N-layers 13 and 14 are formed under the electrode 9 and the N type region 3 by diffusing impurities. According to this constitution, the height of the delta-shaped layer 6 is formed longer than the width, a ultrashort channel type FET having the width of 0.1-1mum can be formed, the layer 6 is turned to a gate, the layers 13 and 14 are turned to a source and drain, and a capacity 15 is added, thereby enabling to obtain an IGFET which is highly integrated in height direction.
