摘要: A method for removing dry film resist (DFR) from a fine pitch solder bump array on a semiconductor wafer provides for pre-soaking the wafer in a chemical bath then turbulently exposing the wafer to a chemical solution, both steps taking place in batch processing with the wafers processed in a vertical position. The wafers are then individually processed through a chemical spinning operation in which a chemical solution is dispensed from a spray nozzle while motion such as spinning is imparted the horizontally disposed wafer. The spin speed of the chemical spraying process may then be increased to accelerate physical removal of residue. Deionized water rinsing and spin-drying provide a solder bump array void of any DFR or other residuals.

摘要: In accordance with the objectives of the invention a new method and apparatus is provided for the removal of by-products resulting from a dry-film removal process. The conventional method and apparatus for controlling a dry-film removal process is extended by the addition of a Dry-Film Remove Pre-Filter System, which significantly enhances the capability of filtering a dry-film removal solution.
