Assignee: DEXERIALS CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A multilayer substrate comprising:
semiconductor substrates each having a through hole of a plurality of through holes and a plated film on an inner surface thereof, the semiconductor substrates being laminated to each other, wherein:
a particle group formed from a plurality of adjacent conductive particles is present at least at a position where a first pair of the through holes face each other as viewed in a first direction corresponding to a plan view of the multilayer substrate, wherein each conductive particle in the particle group includes a metal coating and a core resin material, and
the multilayer substrate has a connection structure in which the first pair of the through holes are connected by the particle group, and the semiconductor substrates are bonded together by an insulating adhesive, wherein
a first conductive particle in the particle group includes a first surface directly contacting the insulating adhesive, the first surface protruding convexly towards the insulating adhesive as viewed in a second direction, and
the second direction is perpendicular to the first direction.
