Abstract:
A method of separating one or more semiconductor substrates from one or more support substrates, the method comprising the steps of:a) providing an apparatus having: i) a top cassette having: 1) a plurality of vertical slots, and 2) one or more small bars for stopping the support substrate inside the top cassette; and ii) a bottom cassette having a plurality of vertical slots; b) vertically inserting the semiconductor substrate into said slot of the top cassette while the semiconductor substrate is coupled to the support substrate, wherein a first surface of each semiconductor substrate is positioned substantially parallel to a force of gravity during the inserting step; c) supporting the support substrate above the small bars in the top cassette; d) introducing the apparatus to a dissolving agent to separate the semiconductor substrate from the support substrate, wherein the first surface of each semiconductor substrate is positioned substantially parallel to the force of gravity during the introducing step, and wherein the force of gravity moves the semiconductor substrate from the top cassette towards the bottom cassette.
