【発明が解決しようとする課題】
従来では、検査済みの基板をロボット等によって測定ステージからカセットに収納しないと、次に検査する基板をその測定ステージに搬送させることができない。そのために、検査装置の能率が向上しても基板一枚当たりの検査工程にかかる時間が長くなる。そこで、本発明の課題は、カセットと測定ステージの間で効率良く基板を搬送する簡易な構成の基板搬送装置を提供することにある。
【0005】
【課題を解決するための手段】
上記課題解決のため、本願では、複数の基板を収納可能なカセットと検査装置の測定ステージとの間で基板を搬送する基板搬送装置において、測定ステージの準備位置に対して、一方側に第1の基板搬送アームによってカセットから取り出した基板を受け渡す受渡し位置を、他方側に測定ステージから取り出した基板を第2の基板搬送アームが受け取る受取り位置を、夫々等距離に設け、受渡し位置と受取り位置を結ぶ方向へ往復移動可能でかつ昇降可能な移動体に、受渡し位置から準備位置に往復移動される受渡し部材と準備位置から受取り位置に往復移動される受取り部材を夫々設け、移動体の移動により第1の基板搬送アームに保持された基板を測定ステージに搬送するとともに、測定ステージに保持された基板を受取り位置に搬送するようにし、測定ステージを準備位置において昇降する受渡し部材と受取り部材に干渉しないように形成した。
【0006】
具体的には、カセットを受渡し位置の前側と受取り位置の前側に夫々載置し、受渡し位置と供給側カセットを結ぶ方向へ往復移動可能でかつ昇降可能な移動体に受渡し部材に基板を受け渡す第1の基板搬送アームを設け、受取り位置と収納側カセットを結ぶ方向へ往復移動可能でかつ昇降可能な移動体に受取り部材から基板を受け取る第2の基板搬送アームを設け、両基板搬送アームを受渡し位置と受取り位置において昇降する受渡し部材と受取り部材に干渉しないようにした。
【0007】
【発明の実施の形態】
実施の形態について図面を参照して説明する。図1〜3に示す基板搬送装置1は、複数の基板Wを収納可能なカセット2a,2bと検査装置3の測定ステージ4との間で基板Wを搬送するものである。検査装置3にはフォーサ5aが前後左右に移動する平面サーボモータ5が配設され、フォーサ5aの前端部に前方へ張出す測定ステージ4が設けられている。その測定ステージ4には、基板Wを保持するように複数の位置決め部材6が設けられている。本実施形態の検査装置3は、基板Wを準備位置Aから測定位置A1に移動させた後、測定ステージ4の上方に設置されたカメラ7によって基板Wの画像を取り込み、画像処理装置(図示しない)によって基板Wの検査を行うものである。測定ステージ4の準備位置Aに対して、一方側に供給側カセット2aから取り出した基板Wを受け渡す受渡し位置Bを、他方側に測定ステージ4から取り出した基板Wを受け取る受取り位置Cを、夫々等距離に設けてある。受渡し位置Bの前側と受取り位置Cの前側には夫々カセット置場8が設けてある。カセット置場8には複数の基板Wを収納可能な供給側カセット2a,収納側カセット2bが夫々載置されている。
【0008】
測定ステージ4の前側にはアクチュエータ9がブラケット10を介して設置され、アクチュエータ9の第1可動体9aが受渡し位置Bと受取り位置Cを結ぶ方向へ移動するようになっている。第1可動体9aにはロッド部11aが昇降可能なシリンダ11が取り付けてあり、ロッド部11aには移動体12が取り付けられている。移動体12の両端側には、受渡し部材13と受取り部材14が前記準備位置Aと受渡し位置B(受取り位置C)と等しい距離となるように夫々取り付けてある。このことから、第1可動体9aが受渡し位置Bと受取り位置Cの間を往復移動することで、受渡し部材13は受渡し位置Bと準備位置Aとの間を往復移動し、受取り部材14は準備位置Aと受取り位置Cとの間を往復移動するようになっている。前記ロッド部11aは、図4(a)に示すように移動体12を降下させた時には、受渡し部材13と受取り部材14が測定ステージ4より下側に位置し、図4(b)に示すように移動体12を上昇させた時には、受渡し部材13と受取り部材14が測定ステージ4より上側に位置するように設定されている。また、受渡し部材13と受取り部材14は、準備位置Aで昇降させた時に測定ステージ4と干渉しないように、例えば互いに異なるフォーク状に形成されている。受渡し部材13と受取り部材14には基板Wを保持するように複数の位置決め部材15が設けられている。
【0009】
測定ステージ4の両側にはアクチュエータ16,17がブラケット18を介して設置され、アクチュエータ16,17の第2可動体16a,17aがカセット2の上端位置と下端位置とを結ぶ方向へ移動するようになっている。その第2可動体16a,17aには支持部材19を介してアクチュエータ20,21が取り付けられ、アクチュエータ20,21の第3可動体20a,21aが前記第2可動体16a,17aに対して垂直方向に移動するようになっている。第3可動体20a,21aには移動体22が取り付けてあり、その移動体22には第1,2の基板搬送アーム23,24が取り付けられている。第1の基板搬送アーム23は、受渡し部材13を受渡し位置Bで昇降させた時に受渡し部材13と干渉しないように、例えば互いに異なるフォーク状に形成されている。また、第2の基板搬送アーム24は、受取り部材14を受取り位置Cで昇降させた時に受取り部材14と干渉しないように、例えば互いに異なるフォーク状に形成されている。第1,2の基板搬送アーム23,24には基板Wを保持するように複数の位置決め部材25が設けられている。
【0010】
前記第2可動体16a,17aは、図5(a)に示すように、カセット2の最上段の基板Wを取り出し可能な高さ位置から順次基板Wを取り出し可能なように移動され、図2,3に示すように下端側に移動した時には、第1,2の基板搬送アーム23,24が受渡し位置B、受取り位置Cにおいて測定ステージ4と同一高さとなるように設定されている。また、第3可動体20a,21aは、図3,図5(a)に示すように第3可動体20a,21aが後端側に移動した時には、第1,2の基板搬送アーム23,24が受渡し位置B、受取り位置C或いは、受渡し位置B、受取り位置Cの上方空間に位置し、図5(b)に示すように前端側に移動した時には、第1,2の基板搬送アーム23,24が受渡し位置B、受取り位置Cの前側にある供給側カセット2a,収納側カセット2b内に挿入されるように設定されている。
【0011】
次に、上記のように構成した基板搬送装置1による基板Wの搬送動作について説明する。検査装置3によって基板Wの検査が行われている時には、図1〜3に示すようにロッド部11aを降下して受渡し部材13と受取り部材14を測定ステージ4より下方に位置させてある。そして、第1可動体9aを移動して受渡し部材13を受渡し位置B、受取り部材14を準備位置Cに移動させてある。また、第2可動体17aを下端側に移動して第2の基板搬送アーム24を測定ステージ4と同一高さに移動させてある。この状態において、第2,3可動体16a,20aによって第1の基板搬送アーム23を所定の高さまで上昇させた後、供給側カセット2a内に挿入させる。第1の基板搬送アーム23が未検査の基板W1の下側に移動した後、第2可動体16aによって第1の基板搬送アーム23を僅かに上昇させると、第1の基板搬送アーム23に設けた位置決め部材25により未検査の基板W1が保持される。その状態で、第3可動体20aを後端側に移動して供給側カセット2aから未検査の基板W1を取り出し、第2可動体16aを下端側に移動して第1の基板搬送アーム23を測定ステージ4と同一高さに移動させ、受渡し位置Bに位置させる。
【0012】
その後、検査装置3によって基板Wの検査が完了して測定ステージ4が測定位置A1から準備位置Aに移動すると、シリンダ10により移動体12を上昇させ、第1の基板搬送アーム23から受渡し部材13に未検査の基板W1が受け渡されるとともに、測定ステージ4から受取り部材14に検査済みの基板W2が受け渡される。また、図6(a)の状態で、第1可動体9aを受取り位置Cに向けて移動させる。図6(b)に示すように受渡し部材13が準備位置Aの上方、受取り部材14が受取り位置Cの上方に移動すると、シリンダ10により移動体12を降下させ、受渡し部材13から測定ステージ4に未検査の基板W1が受け渡されるとともに、受取り部材14から第2の基板搬送アーム24に検査済みの基板W2が受け渡される。その後、第1可動体9aを受渡し位置Bに向かって移動させる。測定ステージ4に保持された未検査の基板W1は準備位置Aから測定位置A1に移動した後、検査装置3によって検査される。また、第2の基板搬送アーム24に保持された検査済みの基板W2は、前記検査が行われている間に第2,3可動体17a,21aによって収納側カセット2bの所定位置に収納されるようになっている。そして、供給側カセット2aに収納された未検査の基板W1がすべて収納側カセット2bに収納されるまで繰り返される。
【0013】
このように、受渡し位置Bと受取り位置Cを結ぶ方向へ往復移動可能でかつ昇降可能な移動体12に、受渡し位置Bと準備位置Aとの間で往復移動する受渡し部材13と準備位置Aと受取り位置Cとの間で往復移動する受取り部材14とを設けたことで、検査装置3によって基板Wの検査が完了すると、直ちに測定ステージ4から検査済みの基板W2を受取り位置Cへ搬出するとともに、次に検査する基板W1を受渡し位置Bから測定ステージ4に搬入することができる。また、カセット2a,2bと受渡し位置B、受取り位置Cとの間で基板Wを搬送させる第1,2の基板搬送アーム23,24を備えているので、検査装置3の検査時間を利用して、カセット2aから未検査の基板W1を受渡し位置Bに搬送することができるとともに、受取り位置Cから検査済みの基板W2をカセット2bに収納することができる。よって、未検査の基板W1と検査済みの基板W2をほぼ同時に交換させることで、検査装置3の停止時間を短くでき基板W一枚当たりの検査工程にかかる時間を短くできる。
【0014】
【発明の効果】
以上のように本願では、基準位置の測定ステージの一方側に受渡し位置を、他方側に受取り位置を、夫々等距離に設け、受渡し位置と受取り位置を結ぶ方向へ往復移動可能でかつ昇降可能な移動体に受渡し部材と受取り部材を夫々設け、測定ステージと受渡し部材と受取り部材を、基準位置において受渡し部材と受取り部材が測定ステージに対して干渉しないようにしたので、移動体によって受渡し部材と受取り部材を昇降、移動させるのみで、測定ステージ上から検査済みの基板を取出すと共に未検査の基板を搬送でき、基板の着脱を瞬時に行うことができて装置の稼働率を向上できる。また、測定ステージ上への基板の着脱を移動体の昇降及び移動によって行えるので、装置の構成を簡易にでき、製造コストを低くできる。
【0015】
更に、カセットを受渡し位置の前側と受取り位置の前側に夫々載置し、受渡し位置と供給側カセットを結ぶ方向へ往復移動可能でかつ昇降可能な移動体に受渡し部材に基板を受け渡す第1の基板搬送アームを設け、受取り位置と収納側カセットを結ぶ方向へ往復移動可能でかつ昇降可能な移動体に受取り部材から基板を受け取る第2の基板搬送アームを設け、両基板搬送アームを受渡し位置と受取り位置において昇降する受渡し部材と受取り部材に干渉しないようにしたので、検査作業中に、簡易な機構によりカセットから取り出した基板を受渡し部材に載置できると共に、簡易な機構により受取り部材上の基板をカセットに収納でき、基板の搬送を安価な装置で省力化できる。

[0011]
Next, the operation of transporting the substrate W by the substrate transport apparatus 1 configured as described above will be described. When the inspection apparatus 3 is inspecting the substrate W, as shown in FIGS. 1 to 3, the rod portion 11 a is lowered and the delivery member 13 and the reception member 14 are positioned below the measurement stage 4. Then, the first movable body 9a is moved to move the delivery member 13 to the delivery position B and the delivery member 14 to the preparation position C. Further, the second movable body 17 a is moved to the lower end side, and the second substrate transfer arm 24 is moved to the same height as the measurement stage 4. In this state, the first substrate transport arm 23 is raised to a predetermined height by the second and third movable bodies 16a and 20a, and then inserted into the supply side cassette 2a. When the first substrate transport arm 23 is slightly raised by the second movable body 16a after the first substrate transport arm 23 has moved to the lower side of the uninspected substrate W1, the first substrate transport arm 23 is provided with the first substrate transport arm 23.

By providing the receiving member 14 that reciprocates between the receiving position C and the inspection of the substrate W by the inspection apparatus 3, the inspected substrate W2 is immediately carried out from the measurement stage 4 to the receiving position C. Then, the substrate W1 to be inspected next can be carried into the measurement stage 4 from the delivery position B. Further, since the first and second substrate transport arms 23 and 24 for transporting the substrate W between the cassettes 2a and 2b and the delivery position B and the reception position C are provided, the inspection time of the inspection apparatus 3 is used. The uninspected substrate W1 can be transferred from the cassette 2a to the delivery position B, and the inspected substrate W2 from the reception position C can be stored in the cassette 2b. Therefore, by replacing the uninspected substrate W1 and the inspected substrate W2 almost simultaneously, the stop time of the inspection apparatus 3 can be shortened, and the time required for the inspection process per substrate W can be shortened.
