Abstract:
1. A method of forming a semiconductor device assembly, comprising: forming a semiconductor device assembly that includes a support substrate, a transfer structure comprising a tape, and a plurality of semiconductor structures between the support substrate and the transfer structure, wherein individual semiconductor structures of the plurality of semiconductor structures include an active surface, and wherein forming the semiconductor device assembly includes removing the support substrate to expose the active surface of the individual semiconductor structures and the trench between the individual semiconductor structures, wherein the active surface of the individual semiconductor structures is arranged to emit and/or receive light, and wherein removing the support substrate includes disposing a chemical etchant at the trench while the tape is attached to the individual semiconductor structures; attaching the active surface of the individual semiconductor structures to a carrier substrate, wherein the carrier substrate is substantially optically transmissive such that the active surface can emit and/or receive the light through the carrier substrate; and processing the plurality of semiconductor structures on the carrier substrate with the support substrate removed.
