Zusammenfassung: | PROBLEM TO BE SOLVED: To detect the height position of a lift pin promptly, in a substrate processing apparatus capable of freely protrude and retract for a placing table of a substrate, and including multiple lift pins for delivering the substrate.SOLUTION: A jig 7 provided with a lighting circuit in a container 71, having the bottom formed with the same size as that of a substrate, is prepared. The bottom of the container 71 is constituted of a conductive path plate 72, an insulation material 23 is provided around a region P1 for insulating the region P1 corresponding to one lift pin 4 and the other region P2, and the opposite ends of the lighting circuit are connected with the regions P1, S2, respectively. When placing the jig 7 on a placing table 2, and bringing the other lift pin 4 into contact with the region P2 in a state where the one lift pin 4 is in contact with the region P1, the lift pines 4 are interconnected electrically, and thereby an LED 77 in the jig 7 is lighted. Light at this time is detected by a photodetector 60, and a servo motor 5 of an adjustment object lift pin 4 is controlled.SELECTED DRAWING: Figure 2
【課題】基板の載置台に対して突没自在で、基板の受け渡しを行うための複数のリフトピンを備えた基板処理装置において、リフトピンの高さ位置の検出を速やかに行うこと。【解決手段】底部が基板と同じ大きさに形成された容器71内に点灯回路が設けられた治具7を用意する。容器71の底部は導電路プレート72により構成され、一本のリフトピン4に対応する領域P1と他の領域P2とを絶縁するために領域P1の周囲に絶縁材23が設けられ、点灯回路の両端は夫々領域P1、S2に接続される。治具7を載置台2に載置し、領域P1に1本のリフトピン4を接触させた状態で他のリフトピン4を領域P2に接触させると、リフトピン4同士は電気的に接続されていることから、治具7内のLED77が点灯する。このときの光を光検出部60で検出し、調整対象のリフトピン4のサーボモータ5を制御する。【選択図】図2 |
