Title: Vacuum chuck stage for wafer
Inventor: AYAGUCHI YASUO
IPC: H01L21/68
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent the movement of a wafer when a vacuum chuck stage for wafer is used by forming through-holes through a vacuum chuck plate and making the holes communicate with each other and, at the same time, exhausting a gas, while the flow rate of the gas is detected and automatically adjusted. SOLUTION: Through-holes 12b having the same diameter are formed through the vacuum chuck plate 12 of a vacuum chuck stage 10 for wafer and the holes 12b communicate with the flowing-in ports 13a of a flow switch 13 through first connectors 14. The flowing-out ports 13b of the switch 13 communicate with a communicative hole 15 through second connectors 16. All of the ports 13b communicate with the hole 15 and further communicate with a vacuum pump through an exhaust pipe 17. A partially broken-off semiconductor wafer 11 is placed on the upper surface 12a of the plate 12 and fixed by suction by operating a vacuum pump. When air flows through the holes 12b in the area where the wafer 11 does not exist, the flow switches 13 of the holes 12b work and, the flow rate of the air is reduced or the flow of the air is stopped.  On the other hand, the holes 12b in the placing area of the wafer 11 are maintained in vacuum. Therefore, the occurrence of such a trouble that the wafer 11 moves during characteristic measurement or scribing work can be prevented.

IPC: G11B21/08
Filed: 1985-10-16
Abstract: PURPOSE:To attain a quick and accurate searching action without limiting the moving speed of a pickup by opening a control loop when a speed detecting signal reaches a prescribed level. CONSTITUTION:An arithmetic processing circuit 12 calculates the distance between the present and target positions of a pickup and controls a reference voltage generating circuit 27 based on the information on said distance to produce a voltage signal in response to the distance. A comparator 26 compares the voltage signal given from the circuit 27 with the voltage signal given from a range detecting circuit 25 and delivers this difference voltage to a feed motor 21 via a changeover switch 14, a comparator 19 and an amplifying circuit 20. Thus the pickup is moved. The output voltage of an integration circuit 24 is changed toward the level of the voltage signal delivered from the circuit 27 in response to the moving distance of the pickup. Therefore, the moving speed of the pickup is accelerated up to a certain time point and then decelerated.
