Method for controlling post-processing operations

A system and method for post-processing of polymeric items having a liquid component and a predetermined heat deflection temperature is provided. The system includes a washing station to spray water at elevated temperature and pressure on the items while maintaining the temperature of the item below the heat deflection temperature. Then using a water distillation system to separate the water from the water mixed with the liquid polymer component by evaporating the water using heating coils with surface that is not conducive to adhesion of the liquid polymer component and then condense the water vapor into liquid water. The system may further include a spin station to separate the liquid polymer component by spinning the item. The system may further include one or more processing stations to rinse the item, dry the item, cure the item, remove the item from a tray to which the item may be attached and clean trays after removing the item. A conveyor system may be used to automate the post-processing of the items.

Semiconductor arrangement and method for making

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.
