Abstract
In general, in one aspect, the invention features methods that include forming a first lithography mask including a pattern corresponding to an array of filters for a liquid crystal display, using a lithography tool to project an image of the pattern onto multiple locations of a substrate to form an exposed substrate, and forming a second lithography mask from the exposed substrate.
