    Abstract: The present invention relates to a substrate cleaning system and a substrate cleaning method for cleaning a substrate. The substrate cleaning system (50) includes a heater (51), a chemical-liquid diluting module (52), and a cleaning module. A temperature of the diluted-chemical-liquid mixed by the chemical-liquid diluting module (52) is determined to be higher than normal a temperature and lower than a glass transition point of a cleaning member. The cleaning member scrubs the substrate (W) with the diluted chemical liquid having the determined temperature supplied to the substrate (W).

  • Patent number: 10008380
    Abstract: A substrate drying apparatus includes a drying gas nozzle configured so that, assuming that a surface WA of the substrate W is a projection plane, regarding the drying gas flow Gf in the nozzle moving direction Dr, a collision position Gfw with the substrate W is located downstream of a projected discharge position Gfv?, the projected discharge position Gfv? being a discharge position from the drying gas nozzle projected on the projection plane. In a three-dimensional space, the drying gas flow Gf is inclined, such that an angle ? formed by an axis Ga of the drying gas flow Gf and a vertical line Wp of the substrate W is in a range from a half contact angle ?/2 to an angle determined by deducting the half contact angle ?/2 from 90°, the half contact angle ?/2 being a half of the contact angle ?.
