摘要： A clean, recirculating and processing method which prevents surface contamination of an object, such as a semiconductor, semi-conductor wafer, glass for LCD or magnetic disk is provided which includes covering the front and rear surfaces of an object to be processed with front and rear shielding plates and allows the object to rotate relative to the front and rear shielding plates. The fluid is supplied between the front surface of the object and the front shielding plate allowing the front surface to be processed. The remaining fluid is collected and recirculated between the rear surface of the object and the rear shielding plate allowing the rear surface of the object to be processed. An apparatus for accomplishing the method is also disclosed.

摘要： To carry out very clean and low-cost fluid processing on both the front and rear surfaces of an object to be processed without generating rubbing particles and without leakage of fluid. A retention member for the object to be processed 18 that retains the object to be processed 17 and a rear shielding plate 15 that prevents the rear surface of the object to be processed from becoming contaminated by excessive fluid flow are mechanically separated. The rear shielding plate 15 is fixed in like manner to a front shielding plate 11, only the retention member for the object to be processed 18 is allowed to rotate making it possible to rigidly connect a supply pipe 22 (that supplies fluid through the rear shielding plate 15) to the rear shielding plate 15. Further, a circulation system is provided that collects fluid which underwent front surface processing in a collection tube 13, circulates that fluid and then supplies it to the rear surface of the object to be processed from a supply pipe.
