    • A vertical trench transistor has a first electrode, a second electrode and also a semiconductor body arranged between the first and second electrodes, there being formed in the semiconductor body a plurality of transistor cells comprising source region, body region, drift region and gate electrode and also contact holes for making contact with the source and body regions, contact being made with the source and body regions by means of the first electrode, and at least the bottom of each contact hole adjoining at least one drift region, so that Schottky contacts between the first electrode and corresponding drift regions are formed at the bottoms of the contact holes. The dimensions and configurations of the body regions or of the body contact regions optionally arranged between body regions and contact holes are chosen in such a way as to avoid excessive increases in electric fields at the edges of the contact hole bottoms.
    • 垂直沟槽晶体管具有第一电极,第二电极和布置在第一和第二电极之间的半导体本体,在半导体本体中形成多个晶体管单元,其包括源极区域,体区域,漂移区域和栅极电极,以及 还接触用于与源区和主体区接触的孔,借助于第一电极与源极和主体区进行接触,并且至少每个接触孔的底部与至少一个漂移区相邻,使得肖特基接触在 第一电极和相应的漂移区形成在接触孔的底部。 选择布置在主体区域和接触孔之间的身体区域或身体接触区域的尺寸和结构被选择为避免接触孔底部边缘处的电场过度增加。
