Wafer fabrication process
摘要:
A wafer fabrication process with removal of haze formation from a pellicalized photomask surface is provided. The wafer fabrication process includes pre-print wafer processing, wafer print processing using at least one photomask having a pellicle, photomask clean processing, wafer print processing using the photomask, and post-print wafer processing. The photomask clean processing step includes directing a laser through the pellicle towards an inorganic particle disposed on the photomask to remove the particle from the photomask by thermal decomposition.
