The silicon wafer and the degreasing material frame are soaked in the water in the degreasing material vehicle. The silicon wafer needs to be manually fished in the water and placed into the material holder. The material holder is manually placed on the wafer inserting machine to insert the wafer. About 5000 silicon wafers are in one plate, each material holder can hold 600-800 silicon wafers at a time, and several material holders are needed to hold the silicon wafers in one plate. The working process needs 1-2 persons to complete. The operator needs to wear gloves to fish the silicon wafers in the water.
