Description

Canon KrF lithography machine uses a 248nm wavelength KrF excimer laser as the exposure light source. It is suitable for more sophisticated semiconductor processes and is widely used in the manufacture of high-performance semiconductor devices. It has better alignment accuracy and plays an important role in 4-inch, 6-inch, 8-inch and 12-inch wafer production lines, providing semiconductor manufacturers with flexibility and efficient production capabilities.

OEM Model Description

The FPA-5000ES3 is a KrF scanner with a 0.73 NA, designed for 130nm production. It is built on the Canon FPA-5000 scanning platform and incorporates experience from previous models. The ES3 has significant refinements, particularly in lens performance, and employs unique lens elements using Canon’s “wavefront engineering” method. Lens testing results show values much smaller than the manufacturing target, in some cases by as much as 30-40%.
