  • Method for the removal of an imaging layer from a semiconductor substrate stack
    Patent number: 7011935
    Abstract: Processes to overcome mistakes, such as, incorrect film thicknesses, poor coating quality, and incorrect feature dimensions made during the lithographic process in multilayer imaging systems are provided. To optimize manufacturing efficiency, it is desirable to be able to remove the top layer (an imaging layer) without having to remove, recoat, and usually cure the bottom layer (undercoat or underlayer). A rework process for removing an imaging layer from a substrate stack is such a process. The stack comprises a substrate, an underlayer adjacent to the substrate, and an imaging layer comprising silicon adjacent to the underlayer.
