Methods and apparatus for reducing the formation of insoluble deposits in semiconductor electrochemical plating equipment or a surface thereof during electrochemical plating, including: removing electrochemical plating equipment or a surface thereof from an electroplating solution, wherein residual electroplating solution is disposed atop the electrochemical plating equipment or a surface thereof, and wherein the residual electroplating solution has a first pH; contacting the residual electroplating solution with a rinse agent having a second pH similar to the first pH to form a rinsate; and removing the rinsate from the electrochemical plating equipment or a surface thereof.

Methods of drying a semiconductor substrate may include applying a drying agent to a semiconductor substrate, where the drying agent wets the semiconductor substrate. The methods may include heating a chamber housing the semiconductor substrate to a temperature above an atmospheric pressure boiling point of the drying agent until a vapor-liquid equilibrium of the drying agent within the chamber has been reached. The methods may further include venting the chamber, where the venting vaporizes the liquid phase of the drying agent from the semiconductor substrate.

In systems and methods for removing a photoresist film off of a wafer, the wafer is moved into a bath of a process liquid in a process tank. The process liquid removes the photoresist film from the wafer. The process liquid is pumped from the process tank to a filter assembly and moved through filter media to filter out solids from the process liquid, and the filtered process liquid is returned to the process tank. A scraper scrapes the filter media to prevent clogging of the filter media by accumulated solids.
