Package for housing semiconductor element and semiconductor device

摘要

A package for housing a semiconductor element includes a base body including a bottom plate section and a frame-shaped side wall section; and an input/output terminal provided so as to pass through the side wall section, the input/output terminal having a plate section on which line conductors are formed, and a vertical wall section which is fixed to the plate section so as to continue to the side wall section and so that the line conductors are sandwiched between the plate section and the vertical wall section and both ends of the line conductors are exposed from the vertical wall section. The vertical wall section has a thick section in a center portion of a side surface of the vertical wall section in a direction along the side wall section, the thick section having thick wall thickness, a lower end of the thick section being fixed to the plate section.

主权项

1. A package for housing a semiconductor element, comprising:
a base body comprising a bottom plate section and a side wall section having a frame shape; and an input/output terminal provided so as to pass through the side wall section, the input/output terminal having a plate section made of ceramics on which line conductors are formed, and a vertical wall section which is made of ceramics and is fixed to the plate section so as to continue to the side wall section and so that the line conductors are sandwiched between the plate section and the vertical wall section and both ends of the line conductors are exposed from the vertical wall section, the vertical wall section of the input/output terminal having a thick section in a center portion of each of a plurality of side surfaces of the vertical wall section in a direction along the side wall section, the plurality of side surfaces being positioned inside and outside the side wall section, the thick section having thick wall thickness, a lower end of the thick section being fixed to the plate section, and wherein the thick section projects from the vertical wall section of the input/output terminal and an end surface of the thick section in a thickness direction thereof extends to an end surface of the plate section, and the line conductors are not covered with the thick section.
