基于不完全匹配的掩膜版进行芯片套刻的校准方案
A Calibration Scheme for Chip Engraving Based on Imperfectly Matched Mask
【摘要】 提出一种校准方案,在套刻曝光一般步骤的基础上进行适当调整,用不完全匹配的掩膜版同样能够实现准确的套刻曝光。研究为提高芯片制备效率、保证对准精度提供了新思路。
【Abstract】 A calibration scheme was proposed that made appropriate adjustments based on the general steps of lithography exposure and achieved accurate lithography exposure using incompletely matched masks. This study provided a new approach to improving chip preparation efficiency and ensuring alignment accuracy.
