Abstract:
A method for performing at least one operation of a testing operation and a burin-in operation on an uncut wafer having two opposing surface using a first plate which includes a biasing mechanism, and a second rigid plate selectively engageable with the first plate, the second rigid plate having a plurality of contact elements extending therefrom and having a cavity for receiving the uncut wafer therein, the method comprising:placing the wafer, in a desired orientation, between the first plate and the second rigid plate with the plurality of contact elements on the second rigid plate engaging corresponding locations on the wafer; and biasing the plurality of contact elements of the second rigid plate against a surface of the wafer by applying an elastic force to an opposing surface to said surface of said wafer with said first plate, said force caused by said biasing mechanism, and said force applied to substantially the entirely of said opposing surface.
