Abstract

La présente invention se rapporte à une technologie de traitement de substrat pour effectuer un traitement de substrat prédéfini sur un substrat en fournissant un liquide de traitement au substrat maintenu par une unité de maintien de substrat rotatif, et en collectant des gouttelettes du liquide de traitement sortant du substrat pendant le traitement de substrat. Dans ce dispositif, un liquide de rinçage de coupelle est fourni directement à une partie de coupelle rotative à partir d'une partie interne de la partie de coupelle rotative tandis que la partie de coupelle rotative tourne autour de l'axe de rotation. Par conséquent, le liquide de traitement est retiré de la partie de coupelle rotative tandis que la quantité d'utilisation du liquide de rinçage de coupelle est réduite, moyennant quoi la partie de coupelle rotative peut être gardée propre.
