Abstract

A method includes forming a transistor over a front side of a substrate, in which the transistor comprises a channel region, a gate region over the channel region, and source/drain regions on opposite sides of the gate region; forming a front-side interconnect structure over the transistor, wherein the front-side interconnect structure includes a dielectric layer and conductive features; and bonding the front-side interconnect structure to a carrier substrate via a bonding layer, in which the bonding layer is between the front-side interconnect structure and the carrier substrate, and the bonding layer has a higher thermal conductivity than the dielectric layer of the front-side interconnect structure.
