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.

The second switch is connected between the common node and a second supply voltage terminal to receive the ground voltage. The protector is connected to the common node to limit a voltage output of the first supply voltage terminal in response to a voltage of the common node.

Abstract: A wafer guide and a semiconductor wafer drying apparatus using the same are disclosed. The wafer guide includes a body and supporters formed on the body. The supporters present a plurality of grooves to engage and support a periphery of a wafer. A discharge structure, e.g., a discharging hole, promotes flow of a cleaning solution away from the grooves thereby more effectively drying the wafer by more readily discharging the cleaning solution by way of the discharging structure. The discharging structure reduces undesirable accumulation of the cleaning solution, such as deionized water, in the grooves during a wafer cleaning process. In some embodiments, a pump actively draws fluid away from the discharge structure.
