Lithography defects
Web1 aug. 2015 · Defects can come from contamination or cleaning. Even with maskless e-beam lithography, the in situ programmable mask can be contaminated. Defects can also be generated during wafer exposure, wafer processing, and non-litho processing. Solutions are provided and their practicality discussed. Webdefects within the ML stack will cause printable defects at the wafer, and thus the reflective ML deposition process must essentially produce defect-free or near defect-free …
