  • Patent number: 10274819
    Abstract: A method for fabricating a pellicle for EUV lithography processes includes placing a hard mask in contact with a surface of a substrate. In some embodiments, the hard mask is configured to pattern the surface of the substrate to include a first region and a second region surrounding the first region. By way of example, while the mask in positioned in contact with the substrate, an etch process of the substrate is performed to etch the first and second regions into the substrate.

  • Publication number: 20180332677
    Abstract: Additive color mixing across the visible spectrum was demonstrated from a light emitting diode (LED) pixel comprising of red, green, and blue subpixels monolithically integrated and enabled by local strain engineering. The device was fabricated using a top-down approach on a metal-organic chemical vapor deposition-grown sample consisting of a typical LED epitaxial stack. The three color subpixels were defined in a single lithographic step. The device was characterized for its electrical properties and emission spectra under an uncooled condition, which is desirable in practical applications. The color mixing was controlled by pulse width modulation and the degree of color control was also characterized.
