Abstract:
1. A liquid processing apparatus comprising: a processing container surrounding a processing chamber in which a plurality of substrates to be processed are accommodated, the substrates being shaped in circular plates; a substrate holder arranged in the processing container for holding the substrates which are juxtaposed in an axial direction of the circular substrates in such a way that processing surfaces of the substrates are arranged in parallel with each other and for rotating the substrates about the axis of the circular substrates; and a nozzle arranged in the processing container for supplying the substrates with a processing liquid thereby to carry out a liquid process, the nozzle having ejecting orifices to eject the processing liquid in a plane which is substantially parallel with the substrates, the ejecting orifices being formed so as to eject the processing liquid towards substantial centers of the substrates held by the substrate holder and obliquely to the processing surfaces of the plural substrates in such a way that the plane of ejecting processing liquid and the surface of the substrates forms a little angle, wherein the nozzle comprises: a nozzle body provided with a plurality of pedestals formed corresponding to the substrates to be processed; and nozzle members attached to the plurality of pedestals, the nozzle members having the ejecting orifices formed therein; and wherein surfaces of the pedestals incline so that the nozzle members can eject the processing liquid obliquely to the processing surfaces of the substrates held by the substrate holder, in such a way that the plane of ejecting processing liquid and the surface of the substrates forms a little angle.
