Abstract:
1. A method of forming a semiconductor device, the method comprising: providing a first substrate; providing a carrier structure, the carrier structure comprising a first carrier substrate and a second carrier substrate, the first carrier substrate being thicker than the second carrier substrate, a first adhesive being interposed between the first carrier substrate and the second carrier substrate, the first carrier substrate and the second carrier substrate being rigid; attaching the first substrate to a first surface of the carrier structure, one of the first carrier substrate and the second carrier substrate having a larger difference in thickness from the first substrate being interposed between the other of the one of the first carrier substrate and the second carrier substrate and the first substrate; and processing the first substrate, the first carrier substrate and the second carrier substrate not providing electrical functionality to the first substrate.
