摘要： 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 α 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 θ/2 to an angle determined by deducting the half contact angle θ/2 from 90°, the half contact angle θ/2 being a half of the contact angle θ.
