  • Patent number: 9546423
    Abstract: Embodiments relate to a deposition device that operates in two modes: a deposition mode, and a cleaning mode. In the deposition mode, modular injectors inject materials onto a substrate to form a layer. In the cleaning mode, the deposition device is cleaned without disassembly by injecting a cleaning gas. The injector module assembly may be cleaned in the cleaning mode by injecting cleaning gas through an exhaust for removing reactant precursor and routing the cleaning gas from the exhaust to another exhaust for removing source precursor. Alternatively, the injector module assembly is cleaned by injecting cleaning gas into a passage between an injector for injecting a source precursor and another injector for injecting a reactant precursor, and routing the cleaning gas to one of the exhausts in the cleaning mode.

  • Publication number: 20160340779
    Abstract: A radical reactor including an elongated structure received within a chamber of a body of the radical reactor. Radicals are generated within a radical chamber formed in the elongated structure by applying a voltage signal across the elongated structure and an electrode extending within the radical chamber. The radicals generated in the radical chamber are routed via a discharge port of the elongated structure and a conduit formed in the body of the radical reactor onto the substrate.

  • Patent number: 9435030
    Abstract: A radical reactor including an elongated structure received within a chamber of a body of the radical reactor. Radicals are generated within a radical chamber formed in the elongated structure by applying a voltage signal across the elongated structure and an electrode extending within the radical chamber. The radicals generated in the radical chamber are routed via a discharge port of the elongated structure and a conduit formed in the body of the radical reactor onto the substrate. The discharge port and the conduit are not aligned so that irradiation generated in the radical chamber is not directed to the substrate.

  • Publication number: 20150360242
    Abstract: Embodiments relate to an injection module assembly (IMA) including a body and replaceable injectors installed in a module block. Each of the injectors includes a protruding leg that is received in a support hole formed in the module block. The protruding leg provides support for the injector while an end block at an opposite end of the injector is secured to the module block. The end block and the protruding leg enable convenient mounting or removal of the module.

  • Publication number: 20150361548
    Abstract: Embodiments relate to an injection module assembly (IMA) including a body and injectors installed in a module block. The body is formed with a plurality of openings defined by walls extending from the bottom surface to the top surface. Each of the walls includes bulging ridges at the bottom along bottom portions of the injectors. The bulging ridges prevent gas or radicals injected by adjacent injectors from mixing at locations other than on the top surface of a substrate placed below the IMA. Accordingly, the injectors can be placed with closer proximity to each other despite the compact size of the IMA.
