Latest Patents

Jinhong Kim holds a patent for "Photoresist-free photolithography, photoprocessing tools, and methods with VUV or deep-UV lamps." This invention introduces a fabrication tool that utilizes at least one flat lamp photon source or an array of flat lamps to non-thermally ablate polymer material from a surface. The process does not require photoresist, and the desired photoablated pattern is achieved by placing a photolithographic mask between the lamp(s) and the surface to be processed. The methods outlined in the patent allow for the patterning of organic polymer and the deposition of materials by breaking bonds in deposition precursors with photons from a microplasma array. Additionally, one method converts organic polymer material to have a hydrophilic surface. The tool described in the patent is compact, with dimensions comparable to a typical paperback book in width and depth, and a height similar to that of a coffee cup.
