Designed to transfer wafer from the input cassette to output cassette. The machine is desinged with two standard load ports that is able to fit 8" SEMI standard open cassette, 12" FOUP cassette and 12" FOSB cassette. The mapping sensor in the system is able to detect any wafer presence, absence, cross slot, double wafer inside the cassette. A robotic arm is integrated with the end effector which is using Bernoulli or Vaccuum suction types to transfer the wafer to the output cassette depending on the wafer features). The WSS8000 is capable of perfoming wafer transfer with 5 sorting methods, such as, Wafer ID sorting, sequential sorting, drag & drop sorting, sub-lot wafer sorting and slot to slot sorting.
