  • High refractive index nanoimprintable resin for optical waveguide applications
    Patent number: 12222543
    Abstract: Disclosed is a nanoimprintable resin for use in optical waveguide applications. The nanoimprintable resin includes a base resin, metal oxide nanoparticles, and a photoinitiator. A cured film of the nanoimprintable resin exhibits a refractive index greater than or equal to 1.8 (589 nm), such as 1.9 (599 nm), according to ASTM D1218-21 at 25° C.
    Type: Grant
    Filed: November 18, 2022
    Date of Patent: February 11, 2025
    Assignee: Microsoft Technology Licensing, LLC
    Inventors: Atul Bhaskar Chaudhari, Klaus Henrik Valtteri Kalima, Mervi Kaarina Ylä-Jarkko, Pasi Petteri Heinonen
  • Additive manufacturing of polishing pads
    Patent number: 12006442
    Abstract: A system, formulation, and method for additive manufacturing of a polishing layer of a polishing pad. The formulation includes a urethane acrylate oligomer based on a difunctional polyol or difunctional polythiol. The techniques includes selecting the difunctional polyol or the difunctional polythiol to affect a property of the polishing layer. The formulation also includes a monomer and a photoinitiator. The viscosity of the formulation is applicable for 3D printing of the polishing layer.
