Title: Automatic sucking system for semiconductor wafer
Inventor: ISHIHARA AKIRA
IPC: H01L21/78
Filed: 1986-12-18
Abstract: PURPOSE:To detect an error of the suction of a frame by a frame-chuck table by judging whether a pressure-detecting means has detected a change in the pressure of the table during a prescribed time after the table has started to such the frame. CONSTITUTION:If a solenoid valve VL4 which is installed in connection with a vacuum chuck of a frame-chuck table 50 is actuated and the table 50 starts to such a semiconductor wafer frame 4, a timer inside a control unit is cleared. It is judged by a detection signal of a pressure switch PUSW 4 whether the table 50 has sucked the positioned frame 4. If the table 50 has sucked the frame 4, the pressure inside the vacuum chuck is lowered and the PUSW 4 is set to an ON state. If this PUSW 4 is turned off, said timer confirms whether a time limit has been exceeded or not. If the time limit has been exceeded, it is judged that the frame 4 has not been sucked by the table 50 for one cause or another, and an error is displayed.
