Abstract :
In this paper, a study of resist strip in three different aqueous ozonated chemistry processes is reported. This new environmental friendly process is considered mainly as an alternative for sulfuric based processes. It has potential to reduce the cost of ownership (CoO) and environmental impact of the current resist strip processes. Implementation of any of these new processes can be done on existing equipment in the production area without major modifications
