Abstract
A semiconductor structure fabrication method for removing a tape physically attached to a device side of the semiconductor substrate by an adhesive layer of the tape, wherein the adhesive layer comprises an adhesive material. The method includes the step of submerging the tape in a liquid chemical comprising monoethanolamine or an alkanolamine for a pre-specified period of time sufficient to allow for a separation of the tape from the semiconductor substrate without damaging devices on the semiconductor substrate.
