Abstract:
A method for manufacturing a semiconductor die includes providing an SOI semiconductor wafer including a substrate, an insulating layer over the substrate, and a device layer over the insulating layer. A surface of the SOI semiconductor wafer opposite the substrate is mounted to a temporary carrier mount, and the substrate is removed, leaving an exposed surface of the insulating layer. A high-resistivity gold-doped silicon substrate is then provided on the exposed surface of the insulating layer. By providing the high-resistivity gold-doped silicon substrate, an exceptionally high-resistivity substrate can be achieved, thereby minimizing field-dependent electrical interaction between the substrate and one or more semiconductor devices thereon. Accordingly, harmonic distortion in the semiconductor devices caused by the substrate will be reduced, thereby increasing the performance of the device.

Abstract:
A production of voids between substrates is prevented when the substrates are bonded together, and the substrates are bonded together at a high positional precision while suppressing a strain. A method for bonding a first substrate and a second substrate includes a step of performing hydrophilization treatment to cause water or an OH containing substance to adhere to bonding surface of the first substrate and the bonding surface of the second substrate, a step of disposing the first substrate and the second substrate with the respective bonding surfaces facing each other, and bowing the first substrate in such a way that a central portion of the bonding surface protrudes toward the second substrate side relative to an outer circumferential portion of the bonding surface, a step of abutting the bonding surface of the first substrate with the bonding surface of the second substrate at the respective central portions, and a step of abutting the bonding surface of the first substrate with the bonding surface of the second substrate across the entirety of the bonding surfaces, decreasing a distance between the outer circumferential portion of the first substrate and an outer circumferential portion of the second substrate with the respective central portions abutting each other at a pressure that maintains a non-bonded condition.
