  • Patent number: 11043393
    Abstract: Apparatus, systems, and methods for processing a workpiece are provided. In one example implementation, the workpiece can include a silicon nitride layer and a silicon layer. The method can include admitting an ozone gas into a processing chamber. The method can include exposing the workpiece to the ozone gas. The method can include generating one or more species from a process gas using a plasma induced in a plasma chamber. The method can include filtering the one or more species to create a filtered mixture. The method can further include exposing the workpiece to the filtered mixture in the processing chamber such that the filtered mixture at least partially etches the silicon nitride layer more than the silicon layer. Due to ozone gas reacting with surface of silicon layer prior to etching process with fluorine-containing gas, selective silicon nitride etch over silicon can be largely promoted.

  • Patent number: 10698516
    Abstract: A flexible touch-sensing component is formed on a release film by support provided from a first carrier substrate and a second carrier substrate. Then, the flexible touch-sensing component can be attached onto non-planar and curved cover plates through the reloading of a third carrier substrate, so that the touch panel can be lighter and thinner, and have a lower processing cost. In addition, the flexible touch-sensing component uses a film sensor that includes a metal nanowire conductive layer. Since the silver nanowire has flexibility, the touch sensor and the touch panel in the present disclosure can be used in flexible touch-sensing devices and curved-surface touch-sensing devices. Furthermore, based on application of an adhesive reactive ink, the released touch panel can be directly attached to target carrier substrate without adding an auxiliary layer of optical glue or hydrogel glue.
