Abstract:
1. A reusable apparatus for performing at least one operation for a wafer having a plurality of semiconductor dice comprising: a first support member for receiving the wafer in a predetermined orientation, the first support member having a plurality of contact members, having a plurality of electrical connectors connected to the plurality of contact members for establishing communication with circuitry used in the at least one operation, and having a cavity for retaining the wafer therein in a predetermined orientation during the at least one operation; a second report member for selectively engaging in the first support member to retain the wafer between the first support member and the second support member; and a biasing assembly including a single floating platform having an area substantially sized for the cavity, the biasing assembly mounted to the second support member, the biasing assembly having a shape for substantially uniformly biasing portions of the plurality of semiconductor dice of the wafer against the plurality of contact members for electrical contact therewith.
