General Information

AZ Aquatar®-VIII A45 and -VIII A30 is a top layer anti-reflective coating for use with g- and i-line. AZ Aquatar®-VIII A45 and -VIII A30 acts like an optical coating at the interface photoresist/air and improves image contrast.
Multiple reflections within the photoresist are also suppressed, the result is generally a reduction of the amplitude of the swing curve to 1/3rd. Application is very simple: it is just spun on top of the photoresist, no additional bake cycle is required and the standard development cycle removes it.
This simple process reduces linewidth variation over topography significantly, however does not suppress reflective notching.
