发明名称 Method for regenerating semiconductor wafers
摘要 A process is described for recycling test wafers used for quality control or damaged wafers used in the context of chip production by regenerative removal of the previously applied layers. The method is based on the object of developing a cost-effective, environmentally friendly and time-saving regeneration method. The object is achieved by removing the applied layers by wet blasting using a specific blast material.
