  • Publication number: 20250076560
    Abstract: A light source module includes a light guide plate, a first light source, multiple first optical microstructures, and multiple second optical microstructures. The first light source is disposed on a side of a first light incident surface of the light guide plate. The first and second optical microstructures are disposed on a bottom surface of the light guide plate, and respectively located in a first and a second zone. A first light receiving surface of each first optical microstructure facing the first light source has a first edge connecting the bottom surface, and a perpendicular bisector of the first edge passes through the first light source. The first zone does not overlap the second zone. A second light receiving surface of each second optical microstructure has a second edge connecting the bottom surface, and a perpendicular bisector of the second edge does not pass through the first light source.

  • Patent number: 12242181
    Abstract: A portion of a buffer layer on a backside of a substrate of a photomask assembly may be removed prior to formation of one or more capping layers on the backside of the substrate. The one or more capping layers may be formed directly on the backside of the substrate where the buffer layer is removed from the substrate, and a hard mask layer may be formed directly on the one or more capping layers. The one or more capping layers may include a low-stress material to promote adhesion between the one or more capping layers and the substrate, and to reduce and/or minimize peeling and delamination of the capping layer(s) from the substrate. This may reduce the likelihood of damage to the pellicle layer and/or other components of the photomask assembly and/or may increase the yield of an exposure process in which the photomask assembly is used.

  • Patent number: 12243775
    Abstract: In one embodiment, a method of forming metal interconnects uses a direct metal etch approach to form and fill the metal gap. The method may include directly etching a metal layer to form metal patterns. The metal patterns may be spaced apart from one another by recesses. A dielectric spacer may be formed extending along the sidewalls of each of the recesses. The recesses may be filled with a conductive material to form a second set of metal patterns. By directly etching the metal film, the technique allows for reduced line width roughness. The disclosed structure may have the advantages of increased reliability, better RC performance and reduced parasitic capacitance.

    Abstract: A control method, suitable for head-mounted devices located in a physical environment, includes following operations. Images of the physical environment are captured over time by the head-mounted devices. Candidate objects and object features of the candidate objects are extracted from the images. Local determinations are generated about whether each of the candidate objects is fixed or not. The object features and the local determinations are shared between the head-mounted devices. An updated determination is generated about whether each of the candidate objects is fixed or not according to the local determinations shared between the head-mounted devices.
