Abstract: Various embodiments of the present disclosure are directed towards an integrated circuit (IC) chip comprising a semiconductor device that is inverted and that overlies a dielectric region inset into a top of a semiconductor substrate. An interconnect structure overlies the semiconductor substrate and the dielectric region and further comprises an intermetal dielectric (IMD) layer. The IMD layer is bonded to the top of the semiconductor substrate and accommodates a pad. A semiconductor layer overlies the interconnect structure, and the semiconductor device is in the semiconductor layer, between the semiconductor layer and the interconnect structure. The semiconductor device comprises a first source/drain electrode overlying the dielectric region and further overlying and electrically coupled to the pad. The dielectric region reduces substrate capacitance to decrease substrate power loss and may, for example, be a cavity or a dielectric layer. A contact extends through the semiconductor layer to the pad.

Abstract: A substrate grinding tool is configured to remove material from a semiconductor substrate in a grinding operation. In the grinding operation, the substrate grinding tool uses a combination of mechanical grinding and a chemical etchant to remove material from the semiconductor substrate. The chemical etchant may be heated to a high temperature, which may increase the etch rate of the chemical etchant. The use of the combination of mechanical grinding and the chemical etchant may increase the grinding rate of the substrate grinding tool for grinding semiconductor substrates, may reduce surface roughness for semiconductor substrates that are processed by the substrate grinding tool, and/or may reduce surface damage for semiconductor substrates that are processed by the substrate grinding tool, among other examples.
