Abstract: A wafer drying method includes submerging a wafer in a cleaning solution in a dry chamber. An organic liquid vapor from an organic liquid is supplied into the dry chamber at a first volumetric supply rate to form an organic liquid layer on a surface of the cleaning solution, the organic liquid layer having at least a prescribed concentration of the organic liquid. The organic liquid vapor is supplied into the dry chamber at a second volumetric supply rate that is lower than the first volumetric supply rate. During and/or following the supplying of the organic liquid vapor into the dry chamber, at least a portion of the wafer is removed from the cleaning solution through the organic liquid layer.

Abstract: A wet processing apparatus includes a bath in which a plurality of semiconductor substrates are to be seated, and which bath has drain valves defining drain openings between a bottom wall and the lower portions of side walls of the bath. Each of the drain valves also includes a gate mounted on the lower portion of one of the side walls. The gates of the drain valves are movable to selectively open and close the drain openings. A plurality of substrates are transferred into the bath and are held under a body of liquid contained in a bath while the substrates are oriented vertically as disposed generally parallel to one another. In this state, the side walls of the baths face the peripheral edges of the substrates at both sides of the substrates. Thus, the substrates are prevented from moving toward and becoming stuck to one another when the liquid is drained from the bath.
