Lithography defects
Webimmersion lithography has resulted in a large number of new studies directed at understanding the new sources of defectivity that are introduced by the immersion … Web4. Immersion defect process characterization and optimizati on As indicated in the introduction, immersion-related defects at the wafer edge can be due to edge damage to the coated material in the EB R area, from the IH passing over this region. On the other hand, defects can be caused by transport of particles present on the bevel.
