  • Publication number: 20250085622
    Abstract: EUV masks and methods of fabrication thereof are described herein. An exemplary method includes receiving an EUV mask having a multilayer structure, a capping layer disposed over the multilayer structure, a patterned absorber layer disposed over the capping layer, and a patterned hard mask disposed over the patterned absorber layer. The method further includes removing the patterned hard mask by performing a first etching process to partially remove the patterned hard mask and performing a second etching process to remove a remainder of the patterned hard mask. The first etching process uses a first etchant, and the second etching process uses a second etchant. The second etchant is different than the first etchant. In some embodiments, the first etchant is a halogen-based plasma (e.g., a Cl2 plasma), and the second etchant is a halogen-and-oxygen-based plasma (e.g., a Cl2+O2 plasma).

  • Publication number: 20230343559
    Abstract: Some implementations described herein provide techniques and apparatuses for overcoming forces that may deflect an injector nozzle into an interior wall of a thin-film furnace. The implementations include a fixture that is coupled to the injector nozzle. The fixture is configurable to lock to a selected property of the injector nozzle to maintain, between a portion of the injector nozzle and the interior wall, a gap. In this way, the portion of the injector nozzle is prevented from colliding with the interior wall and dislodging particulates that may contaminate semiconductor product fabricated using the thin-film furnace.
