Ultrafast laser applications in semiconductor industry

摘要

As features and dimensions become smaller, traditional laser processing in semiconductor industry are hitting its limitations due to the thermal effects inherited in long pulse processing. Ultrafast lasers become more reliable and are available commercially. However, their industrial applications, though very desirable due to their non-thermal nature processing, are only limited to those with high value added. Current status of ultrafast laser applications in semiconductor industry is reviewed. Shortcomings of current commercial systems are analyzed. Requirements for ultrafast laser based production system and future direction are discussed.
