Binary mask vs phase shift mask

WebAbstract In this paper, we will present comparison of attenuated phase shift mask and binary intensity mask at hyper-NA immersion scanner which has been the main stream of DRAM lithography. Some technical issues will be … As phase-shift masks are applied to printing smaller and smaller features, it becomes more and more important to model them accurately using rigorous simulation software, such as Panoramic Technology or Sigma-C. See more Phase-shift masks are photomasks that take advantage of the interference generated by phase differences to improve image resolution in photolithography. There exist alternating and attenuated phase shift masks. A … See more A benefit of using phase-shift masks in lithography is the reduced sensitivity to variations of feature sizes on the mask itself.
