Abstract
A semiconductor device includes a semiconductor element having a rectangular shape in a plan view, and a fixed member to which the semiconductor element is fixed. The semiconductor element is disposed so that a rectangular face of the semiconductor element is faced toward a surface of the fixed member. A part of the rectangular face of the semiconductor element is fixed to the surface of the fixed member. At least corner parts of the rectangular face of the semiconductor element are not fixed to the surface of the fixed member.
Claims8
A semiconductor device comprising:
- a semiconductor element having a rectangular shape in a plan view;
- and
- a fixed member to which the semiconductor element is fixed, wherein
- the semiconductor element is disposed so that a rectangular face of the semiconductor element is faced toward a surface of the fixed member,
- a part of the rectangular face of the semiconductor element is fixed to the surface of the fixed member with a joint material,
- a dent having a pointed bottom is provided on the surface of the fixed member at a position corresponding to each of the corner parts of the rectangular face of the semiconductor element, and
- at least corner parts of the rectangular face of the semiconductor element are not fixed to the surface of the fixed member.
