Method for removing particles from a semiconductor processing tool

摘要

A method for removing particles from a semiconductor processing tool is provided. The method comprises providing a pick-up wafer for picking up particles from a semiconductor processing tool, inserting said pick-up wafer into said semiconductor processing tool and placing the pick-up wafer on a receiving member, applying an electrostatic charge to said pick-up wafer, leaving said pick-up wafer in said semiconductor processing tool for a predetermined dwell time; and removing said pick-up wafer from said semiconductor processing tool. Further, a method for processing semiconductor wafers is provided.
