WebMeasurement of Sidewall Roughness To obtain quantitative measurement on sidewall roughness reduction, an atomic force microscope (AFM) was used to study surface … WebIt is used to remove the residual photoresist scum left on the developed area. Such residual can prevent subsequent dry or wet etching steps and affect the uniformity of the etching rate across the wafer. Descum step can also improve the sidewall profile of the photoresist mask and improve the process uniformity.
