Patent ID: 7795076

Claim:
A method for simultaneously transferring a plurality of integrated circuit dies that are attached to a support structure to a die receptacle structure having a plurality of cells, each cell open at a first surface of the die receptacle structure, comprising: (a) positioning the support structure and die receptacle structure to be closely adjacent to each other such that each die of the plurality of integrated circuit dies attached to the support structure is simultaneously aligned with a corresponding cell of the plurality of cells; (b) simultaneously positioning each aligned die of the plurality of integrated circuit dies attached to the support structure within the corresponding cell of the plurality of cells, wherein a bottom interior surface of each cell has an adhesive material; and (c) simultaneously releasing the plurality of aligned integrated circuit dies from the support structure so that each die resides inside the corresponding cell of the plurality of cells and moving apart the support structure and die receptacle structure; (d) applying a suction at a second surface of the die receptacle structure so that at least a partial vacuum exists in each cell of the plurality of cells due to a hole in the second surface of the die receptacle structure corresponding to each cell and applying a positive pressure at a first surface of the support structure, wherein portions of the die receptacle structure around cells are substantially sharp, wherein step (d) comprises: allowing the applied suction and the positive pressure to cause the sharp portions of the die receptacle structure to cut the support structure around each die of the plurality of dies, such that each die of the plurality of aligned dies is separated from the support structure and is transferred into the corresponding cell of the plurality of cells by the applied suction.
