Abstract
One inventive aspect relates to an attenuated phase shift mask suitable for hyper NA lithographic processing of a device, to a method of making such a mask and to hyper NA lithographic processing using such a mask. The attenuated phase shift mask is made taking into the effect of the numerical aperture of the lithographic system on which the attenuated phase shift mask is to be used.
