Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a first substrate comprising:
a first conductive structure;
a first body over the first conductive structure and comprising an inner sidewall defining a cavity in the first body;
a first interface dielectric over the first body; and
a first internal interconnect in the first body and the first interface dielectric, and coupled with the first conductive structure;

a second substrate over the first substrate and comprising:
a second interface dielectric contacting the first interface dielectric;
a second body over the second interface dielectric; and
a second conductive structure over the second body and comprising a second internal interconnect in the second body and the second interface dielectric;

an electronic component in the cavity; and
an underfill in the cavity between a lateral side of the electronic component and a lateral side of the first body;
wherein the second internal interconnect is coupled with the first internal interconnect at an interface between the first internal interconnect and the second internal interconnect.
