    • A p-type base layer shaped like a well is formed for each of IGBT cells, and a p+-type collector layer and an n+-type cathode layer are formed on a surface opposite to a surface on which the p-type base layer is formed so as to be situated just below the p-type base layer. The p-type base layer of each of the IGBT cells includes a flat region including an emitter region and a bottom surface penetrated by a main trench, and first and second side diffusion regions between which the flat region is interposed. The first side diffusion region is situated just above the n+-type cathode layer and each of the bottom surfaces of the side diffusion regions forms a parabola-shaped smooth curve in longitudinal section. By replacing the p+-type collector layer with the n+-type cathode layer, it is possible to apply features of the above structure to a power MOSFET.
    • 为每个IGBT单元形成像阱状的p型基极层,并且在与p型基极层的表面相对的表面上形成p +型集电极层和n +型阴极层 形成为位于p型基底的正下方。 每个IGBT单元的p型基极层包括包括发射极区域和由主沟槽穿透的底表面的平坦区域,以及插入有平坦区域的第一和第二侧向扩散区域。 第一侧扩散区域位于n +型阴极层的正上方,并且侧向扩散区域的每个底表面在纵向截面中形成抛物线形平滑曲线。 通过用n +型阴极层代替p +型集电极层,可以将上述结构的特征应用于功率MOSFET。
