Abstract:
1. A method for performing at least one operation of a testing operation and a burn-in operation on an uncut wafer having two opposing surfaces 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 uncut wafer having a plurality of semiconductor dice thereon and having a plurality of interconnects between the plurality of semiconductor dice on the uncut wafer, the method comprising: placing the uncut 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 uncut wafer, a plurality of contact elements for contacting at least a portion of an interconnect between at least two semiconductor dice on the uncut wafer for reducing the number of contact elements on the second rigid plate for contacting the plurality of semiconductor dice on the uncut wafer; and biasing the plurality of contact elements of the second rigid plate against a surface of the uncut wafer by applying an elastic force to an opposing surface to the surface of the uncut wafer with the first plate, the force caused by the biasing mechanism, and the force applied to substantially the entirety of the opposing surface.
