Patent ID: 8632112

Claim:
A method of operation of a workpiece displacement system comprising: providing a head including a conduit, a recess port, and a channel, an end of the conduit directly connected with a side of the channel within the recess port; inserting a force distribution member into the recess port, the force distribution member having a top surface section, a workpiece adhesion interface, and an angled sidewall section between the top surface section and the workpiece adhesion interface, wherein the surface area of the top surface section is larger than the surface area of the workpiece adhesion interface such that the force distribution member includes the larger top surface section tapering along the angled sidewall section into the smaller workpiece adhesion interface; and supplying a negative pressure state through the head and the force distribution member such that a workpiece is physically contacted once and only by the workpiece adhesion interface, the workpiece being a semiconductor die.
