概述

The CANON FPA-2500i2 is a stepper system that can be used with a 6” reticle wafer size. It has a numerical aperture of 0.54 / 0.45 and an image field of 22 mm [(X)17mm x (Y)26mm]. The CANON FPA-2500i2 stepper has a printing wavelength of i-line (365 nm) and a resolution of 0.45 μm. It has an illumination lamp of 1.5 kW super-high-pressure mercury and an illumination uniformity of ≤ 1.2 %. It also has alignment modes of TTL Off-Axis He-Ne TV and TTL Off-Axis Broad Band TV with an alignment light source of He-Ne laser (633 nm) and Halogen lamp. Its alignment accuracy is ≤ 0.1 μm (mean + 3 σ) and its throughput is ≥ 52 wafers / hour (8”, 60 shot).
