The bare wafer stocker (BWS600) is the hybrid system that has both stocker function and sorting function (for sorting normal production wafers) by providing the wafer storage area at wafer sorter. Sorting and storing wafers with saving space are available.
- Up to 600 bare wafers can be contained and the divided area control is possible.
- The high speed unit configuration sorts wafers with a suitable transferring pattern.
- The internal shutter mechanism isolates the minienvironment stocker section from sorter section.
- The automatic teaching reduces the teaching time interval.
- IDs on both front surface and back surfaces of a wafer can be read.
