Latest Patents

Kang's latest patents focus on the design and fabrication of phase shift masks. One of his key inventions describes a phase shift mask that includes a first non-phase shift region, a first phase shift region adjacent to the first non-phase shift region, a second non-phase shift region, a second phase shift region adjacent to the second non-phase shift region, and an opaque region interposed between the second phase shift and non-phase shift regions. The first and second non-phase shift regions transmit exposure light at its original phase, while the first and second phase shift regions invert the phase of the exposure light. The manufacturing process involves forming a layer of opaque material on a transparent mask substrate, followed by selective etching to create the necessary regions.
