Abstract:
1. An apparatus for polishing by selectively applying different amounts of pressure to a plurality of locations on a major surface of a semiconductor device structure, comprising: a plurality of independently movable pressurization structures located and oriented to individually apply pressure to a major surface of a semiconductor device structure upon assembly of the semiconductor device structure with the apparatus; and a plurality of actuators, each of the plurality of actuators associated with a corresponding pressurization structure of the plurality of independently movable pressurization structures so as to independently apply pressure to the major surface of the semiconductor device structure in such a way as to change an elevation of a corresponding region of an opposite surface of the semiconductor device structure wherein at least one actuator of the plurality of actuators comprises a vacuum source; and a polishing component including a single polishing pad.
