Patent ID: 11862598
Assignee: ROHM CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a semiconductor element;
a support substrate configured to support the semiconductor element;
an intermediate metal layer interposed between the semiconductor element and the support substrate in a thickness direction of the support substrate, wherein the semiconductor
element and the intermediate metal layer are bonded by solid phase diffusion bonding; and
a first positioning portion including a portion of the semiconductor element and a first portion of the intermediate metal layer and configured to suppress relative movement between
the semiconductor element and the intermediate metal layer,
wherein in the first positioning portion, the portion of the semiconductor element and the first portion of the intermediate metal layer are engaged with each other,
wherein the semiconductor element includes an element facing surface that constitutes the first positioning portion,
wherein the intermediate metal layer includes a first facing surface that constitutes the first positioning portion,
wherein the element facing surface and the first facing surface face each other in a direction intersecting the thickness direction,
wherein the intermediate metal layer includes a first recess that is recessed in the thickness direction from a side where the semiconductor element is located, and
wherein the first facing surface is an inner surface of the first recess.
