Abstract
A cleaning apparatus, method, and dry chamber are provided for cleaning a wafer carrier that holds wafers as part of a semiconductor fabrication process. The cleaning apparatus includes a wet chamber that receives the wafer carrier to be washed and a reservoir in fluid communication with the wet chamber. The reservoir stores a cleaning liquid that is introduced to the wafer carrier within the wet chamber during a washing operation, and a dry chamber is spaced apart from the wet chamber. The dry chamber receives the wafer carrier after the wafer carrier is washed in the wet chamber and holds the wafer carrier during a drying operation. A transport system transports the wafer carrier between the wet chamber and the dry chamber during a cleaning process.
