Techniques for fabricating a device include forming a fabrication layout, such as a mask layout, for a physical design layer, such as a design for an integrated circuit, and identifying evaluation points on an edge of a polygon corresponding to the design layer for correcting proximity effects. Techniques include correcting for proximity effects associated with an edge in a first fabrication layout by determining whether any portion of the edge corresponds to a target edge in a design layer. The first fabrication layout corresponds to the design layer that indicates target edges for a printed features layer. If any portion of the edge corresponds to the target edge, then it is determined whether to establish an evaluation point on the edge. Then it is determined how to correct the edge for proximity effects based on the evaluation point. In case it is determined that no portion of the edge corresponds to the target edge, then no evaluation point is selected on the edge.

Processes are provided for depositing multiple color filter materials on a substrate to form color filters. In a first process, the surface characteristic of a substrate is modified by radiation so that a flowable form of a first color filter material will be deposited on a first area, and converted to a non-flowable form. A second color filter material can then be deposited on a second area of the substrate. In a second process, first and second color filter materials are deposited on separate donor sheets and transferred by radiation to separate areas of the substrate. A third process uses flexographic printing to transfer the first and second color filter materials to the substrate.

Combination of nanolithography and wet chemical etching including the fabrication of nanoarrays of sub-50 nm gold dots and line structures with deliberately designed approximately 12-100 nm gaps. These structures were made by initially using direct write nanolithography to pattern the etch resist, 16-mercaptohexadecanoic acid (MHA), on Au/Ti/SiO_x/Si substrates and then wet chemical etching to remove the exposed gold. These are the smallest Au structures prepared by a wet chemical etching strategy. Also, Dip-Pen Nanolithography (DPN) has been used to generate resist layers on Au, Ag, and Pd that when combined with wet chemical etching can lead to nanostructures with deliberately designed shapes and sizes. Monolayers of mercaptohexadecanoic acid (MHA) or octadecanethiol (ODT), patterned by DPN, were explored as etch resists. They work comparably well on Au and Ag, but ODT is the superior material for Pd. MHA seems to attract the FeCl₃ etchant and results in nonuniform etching of the underlying Pd substrate. Dots, lines, triangles and circles, ranging in size from sub-100 to several hundred nm have been fabricated on these substrates. These results show how one can use DPN as an alternative to more complex and costly procedures like electron beam lithography to generate nanostructures from inorganic materials.
