Abstract:
A semiconductor structure fabrication method comprising:providing a semiconductor substrate having a die side opposite a back side, said die side having a plurality of die formed therein, wherein the die side is situated upon a flexible plastic sheet, the flexible plastic sheet is situated upon a double-sided adhesive tape, and the double-sided adhesive tape is upon a table;forming a recess in the die side of the semiconductor substrate, wherein:a first portion of said semiconductor substrate having at least one die therein is on one side of said recess; anda second portion of said semiconductor substrate having at least one die therein is on a side of said recess opposite that of said first portion of said semiconductor substrate;removing material from said back side of said semiconductor substrate by an abrading operation sufficient to separate from contact the first portion of said semiconductor substrate from the second portion of said semiconductor substrate; andstretching said flexible plastic sheet so as to increase the separation between said first and second portions of said semiconductor substrate.
