摘要: In the polishing system of the present invention, a adhering unit adheres a wafer on a carrying plate using liquid. A polishing unit polishes the wafer using a polishing plate. A feeding unit conveys the carrying plate from the adhering unit to the polishing unit. A dismounting unit removes the wafer from the carrying plate. A first discharging unit conveys the carrying plate from the polishing unit to the dismounting unit. A cleaning unit cleans the vacant carrying plate. A second discharging unit conveys the carrying plate from the dismounting unit to the cleaning unit. A third discharging unit conveys the carrying plate from the cleaning unit to the adhering unit. The units are formed into a loop lines so that the carrying plate is circulated in the loop line and the wafers are polished therein.

摘要: The method and the device of the present invention are capable of uniformly using whole surface of a carrying plate, improving the polishing accuracy of wafers and extending span of life of the carrying plate. The method of adhering a plurality of wafers onto a surface of a carrying plate with predetermined spaces is characterized by regularly shifting wafer adhering positions, at which the wafers are respectively adhered, with respect to a standard position of the carrying plate, in the surface of the carrying plate. The wafer adhering position is regularly shifted when the carrying plate is exchanged or predetermined time elapses.
