GLASS CARRIER CLEANING USING OZONE
Last updated:
Abstract:
In a method for removing an organic adhesive from a glass carrier in a semiconductor manufacturing process, the glass carrier is placed into a process chamber. The glass carrier is rotated and heated sulfuric acid is applied or sprayed onto the glass carrier. Ozone is introduced into the process chamber. The ozone diffuses through the sulfuric acid to the organic adhesive on the surface of the glass carrier. The sulfuric acid and the ozone chemically react with the organic adhesive and remove it from the glass carrier.
