Abstract:
A system for releasing at least a portion of a carrier film from at least one selected semiconductor die, comprising:a base including a plate member configured to be moved laterally within a periphery of a frame supporting the carrier film having a semiconductor wafer adhered thereto, said plate member including a plurality of supports disposed within said periphery, positionable below the carrier film, and sufficiently mutually laterally spaced to permit deflection of portions of the carrier film therebetween responsive to a pressure differential across the carrier film;a vacuum source operatively connected with said base to create a vacuum between said plurality of supports; anda die pick up mechanism, said die pick-up mechanism being laterally positionable proximate to said plate member in a plurality of locations on an opposite side of the carrier film from the plurality of supports.
