Abstract
【解決手段】本構成では、具体的には磁気コンジットを使用してリニアモータによって生み出される磁力の方向を変え、キャリアの移動を妨げないシステム外部の位置にリニアモータを配置することを可能にすることにより、基板処理システム内の複数のレベル間でキャリアを安全且つ安定した状態で移動させることが可能となる。
【選択図】図1
Description
本発明の諸態様は、磁気コンジットを使用して、積み重ね式マルチレベル基板処理システム(stacked, multi−level substrate processing system)上のあるレベルから別のレベルに基板及びキャリアを移動する所要時間を改善することができる。キャリアをエレベータサブシステム内に移動するための機械部品数が減少し、また、隣接する処理チャンバからエレベータチャンバにキャリアを移動する際も最小限のせん断磁力(shear magnetic force)を遮断するだけですむ。また、磁気コンジット、特に磁極片同士が隣接して配列される構成を有する磁気コンジットの使用により、システム全域のキャリア移動を安定化させることができ、その結果、基板がキャリアからはじき出されるリスクを低減させることができる。
