概要（Overview）

The PAS 5500/400 is specified at 0.30um Current i-Line resists are capable to resolve structures down to 0.30 and 0.28um imaging. The maximum MA of the PAS 5500/400 is 0.65. Together with the AERIAL Illuminator the /400 will provide enough process latitude for mass production at 0.30um, extendable down to 0.28 and 0.25um. The highest resolution of the /400 maximized the number of i-Line layers in a full device layer stack.
