Zusammenfassung:To provide a technique capable of improving uniformity of processing relative to a substrate by enlarging a size of a plasma reactor.SOLUTION: A substrate processing device includes: a substrate holding unit 3; a plurality of guards 7; a plasma reactor 1; a first elevation mechanism 15; and a second elevation mechanism 75. The substrate holding unit 3 holds a substrate W. The plurality of guards 7 has a cylindrical shape of surrounding the substrate holding unit 3 and is concentrically provided. The plasma reactor 1 is provided vertically above the substrate holding unit 3 and extends outward from a peripheral edge of the substrate W in a plan view. The plasma reactor 1 radiates plasma to the substrate W in a state where the plurality of guards 7 is positioned at a lower position where an upper end 711 of an inner peripheral surface of an outermost circumference guard 7A is positioned vertically lower than an upper surface of the substrate W and the plasma reactor 1 is positioned at a plasma processing position close to the substrate W.SELECTED DRAWING: Figure 3 【課題】プラズマリアクタのサイズを拡大して基板に対する処理の均一性を向上できる技術を提供する。【解決手段】基板処理装置は基板保持部3と複数のガード7とプラズマリアクタ1と第1昇降機構15と第2昇降機構75とを備える。基板保持部3は基板Wを保持する。複数のガード7は、基板保持部3を囲む筒状形状を有し、同心状に設けられる。プラズマリアクタ1は基板保持部3よりも鉛直上方に設けられており、平面視において基板Wの周縁よりも外側に広がっている。最外周のガード7Aの内周面の上端711が基板Wの上面よりも鉛直下方となる下位置に複数のガード7が位置し、かつ、プラズマリアクタ1が基板Wに対して近接したプラズマ処理位置に位置する処理状態で、プラズマリアクタ1は基板Wにプラズマを照射する。【選択図】図3
