摘要: A method of removing photoresist at the edge of waters in an integrated circuit the method comprising the following steps. A substrate having at least a MOS component region thereabove is provided. A photoresist layer is formed over the substrate. A pattern is defined on the photoresist layer by exposure and development. The photoresist layer at the edge of the substrate is removed by a chemical reagent and centrifugal effect.
