    • A polishing apparatus has a turntable and a top ring for gripping a semiconductor wafer to be polished by an abrasive cloth on the turntable. The polishing apparatus incorporates a loading and unloading unit having a supply holder for holding and supplying a semiconductor wafer to be polished to the top ring at a transfer position, and a reception holder for receiving a polished semiconductor wafer from the top ring at the transfer position. The reception holder and the supply holder are mounted on respective opposite ends of a support block which is angularly movable in a vertical plane by a turning mechanism for moving the supply holder and the reception holder alternatively to the transfer position.
    • 抛光装置具有转盘和顶环,用于夹持通过研磨布在转台上抛光的半导体晶片。 抛光装置包括装载和卸载单元,该装载和卸载单元具有用于在转移位置处将要抛光的半导体晶片保持并提供给顶环的供应保持器,以及用于在转移位置处从顶环接收抛光的半导体晶片的接收保持器 。 接收支架和供电保持器安装在支撑块的相应的相对端上,支撑块的相对的两端可通过转动机构在垂直平面内成角度地移动,用于将供应架和接收架交替地移动到转移位置。
