  • Patent number: 10446559
    Abstract: A method of fabricating a DRAM includes providing a substrate. Later, a first mask layer is formed to cover the substrate. The first mask layer includes a hydrogen-containing silicon nitride layer and a silicon oxide layer. The hydrogen-containing silicon nitride layer has the chemical formula: SixNyHz, wherein x is between 4 and 8, y is between 3.5 and 9.5, and z equals 1. After that, the first mask layer is patterned to form a first patterned mask layer. Next, the substrate is etched by taking the first patterned mask layer as a mask to form a word line trench. Subsequently, the first patterned mask layer is removed entirely. Finally, a word line is formed in the word line trench.

  • Publication number: 20190196633
    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.

  • Patent number: 7113690
    Abstract: An anti-counterfeit method and system by using a nano metal grating, wherein an object to be recognized is formed with the nano metal grating. During the recognition process, an incidental light is applied on the metal grating. In response to the incidental light, the metal grating has its specific optical incidence and reflection characteristics. The object is then identified whether it is genuine or fake by observing the refraction light passing through and reflection light reflected from the metal grating. Further, the incident light beam can be polarized to generate polarized light beams and then irradiated on the metal grating, whereafter the recognition of the object is performed by observing the reflection and refraction lights of the irradiated polarized light beam. The recognition further can be accomplished by rotating the metal grating, thus the intensity of the refraction and reflection lights will accordingly be changed, thereby identifying the object.

    Abstract: A grating interference device with adjustable resolution has high stability and precision adjustment functions. The invention has two reflectors and a beam splitter. One of the reflector is installed on a rotating axis along with an optic fiber or a platform of planar waveguide. Through the rotating axis, this reflector and the platform are maintained at a fixed relative angle and rotate with respect to the other reflector and the beam splitter. The period of the interference grating is controlled by the angle change, producing a grating with a micrometer-order period on the optic fiber or the planar waveguide.
