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

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