    • A semiconductor device includes a semiconductor substrate having a trench on a surface thereof and an embedding member embedding the interior of the trench therewith. While the section of the trench when cut by a first plane perpendicular to the direction of the depth of the trench is defined as a first section and the section of the trench when cut by a second plane perpendicular to the direction of the depth of the trench and closer to the bottom of the trench than the first plane is defined as a second section, the area of the first section is smaller than that of the second section and a minimum radius of curvature of the first section is smaller than a minimum radius of curvature of the second section. As a result, it is possible to lessen the concentration of the electric field into the bottom of the trench.
    • 半导体器件包括在其表面上具有沟槽的半导体衬底和嵌入沟槽内部的嵌入构件。 虽然当垂直于沟槽深度方向的第一平面切割沟槽的部分被定义为第一部分,并且当垂直于沟槽深度方向的第二平面切割沟槽的部分时 并且比所述第一平面更靠近所述沟槽的底部被限定为第二部分,所述第一部分的面积小于所述第二部分的面积,并且所述第一部分的最小曲率半径小于所述第一部分的最小半径 第二部分的曲率。 结果,可以减小进入沟槽底部的电场的浓度。
