The Custom Wafer Laminator combines temperature and pressure to apply a thin plastic laminate to the surface of a wafer. Operator-loaded cassettes are automatically rotated for handling by the ISEL robot, with wafer alignment confirmed by thru-beam sensors.
Wafers are oriented on an ISEL notch finder, then transferred to the heated wafer chuck at the press assembly. Laminate material is automatically positioned over the current wafer on the press, then applied per the time, temperature, and pressure specified in the operator-selected recipe. After the press procedure is completed, the trimmer assembly lowers to accurately trim the laminate to the edge of the wafer. The completed wafer is returned to its original cassette.
Two cassette loaders are installed, enabling continuous wafer processing until sensors alert the operator to a pending end-of-roll condition at the laminate supply. A splicing table is installed within the enclosure, enabling the operator to quickly attach and advance a new laminate roll.
During automated machine operation, operator attention is required only for cassette load/unload and responding to any alerts generated during the process.
