Patent ID: 7578304

Claim:
A cleaning and drying apparatus for a substrate holder chuck including a holding member having a plurality of holding grooves formed in a row to hold a plurality of substrates, the plurality of holding grooves being formed on an upper face of the holding member, the cleaning and drying apparatus comprising: an atomize nozzle including a nozzle hole facing the upper face of the holding member for spraying a cleaning liquid and gas to the upper face of the holding member; a cleaning-liquid nozzle including a nozzle hole facing a side face of the holding member for spraying a cleaning liquid to the side face of the holding member; and a moving mechanism for moving the holding member in relation to the atomize nozzle and the cleaning-liquid nozzle in a direction along the longitudinal direction of the holding member, wherein the atomize nozzle and the cleaning liquid nozzle are provided at different positions along the longitudinal direction of the holding member and thus face two different regions of the holding member when the holding member is in proximity of said nozzles, the two different regions being displaced from each other at least along the longitudinal direction of the holding member so that the atomize nozzle initially sprays the cleaning liquid and the gas to the upper face of respective parts of the holding member and the cleaning-liquid nozzle subsequently sprays the cleaning liquid to the side face of said parts of the holding member as the moving mechanism moves the holding member with respect to the atomize nozzle and the cleaning liquid nozzle along the longitudinal direction from the atomize nozzle to the cleaning liquid nozzle.
