Paper Abstract
The shrink of device node to 65 and 45nm node masks mask manufacturers paying their attention to repair process in
terms of mask cost efficiency. Thus, it is very important to define the repair performance accurately and introduce
adequate tools timely. Usually the repair performance has been expressed as an edge placement error, transmittance
change and quartz damage. We have used the measuring tools such as CD SEM, AFM and AIMS to measure those
factors and the 2D simulator, Solid C to predict the repair performance. In this case, 3D topographical effect is not
considered. However, the 3D topography of pattern becomes quite important for 45 nm node or less.
ArF immersion lithography is the strongest candidate for the 45 nm node. The immersion technology makes it
possible to use of hyper NA systems1. Hyper NA will increase the polarization effect of illumination source2. Therefore,
the topography of pattern is quite important with respect to the intensity and the polarization of various diffraction
orders. This paper presents repair specifications based on the Solid E 3D simulator of the 45 nm node.
