Dispensing liquid containing material to patterned surfaces using a dispensing tube

摘要: Materials that contain liquid are deposited into grooves upon a surface of work piece, such as silicon wafer to form solar cell. Liquid can be dispensed piece paths, under pressure through dispensing tube. The tube mechanically tracks in the groove. may small and rest at groove bottom, with sidewalls providing restraint.
