  • Publication number: 20240186400
    Abstract: According to an exemplary embodiment, a method of forming a vertical device is provided. The method includes: providing a protrusion over a substrate; forming an etch stop layer over the protrusion; laterally etching a sidewall of the etch stop layer; forming an insulating layer over the etch stop layer; forming a film layer over the insulating layer and the etch stop layer; performing chemical mechanical polishing on the film layer and exposing the etch stop layer; etching a portion of the etch stop layer to expose a top surface of the protrusion; forming an oxide layer over the protrusion and the film layer; and performing chemical mechanical polishing on the oxide layer and exposing the film layer.

  • Publication number: 20240145867
    Abstract: A separator for a lithium battery and a method for manufacturing the same are provided. The separator includes a substrate layer and a coating layer. The substrate layer is a polyolefin porous film and has a substrate thickness ranging from 10 to 30 micrometers. The coating layer is coated on the substrate layer, and has a coating layer thickness ranging from 1 to 5 micrometers. The coating layer includes a heat-resistant resin material and a plurality of inorganic ceramic particles glued in the heat-resistant resin material. The heat-resistant resin material has a melting point (Tm) or a glass transition temperature (Tg) of not less than 150° C. An average particle size of the inorganic ceramic particles is 10% to 40% of the coating layer thickness of the coating layer. The inorganic ceramic particles are stacked in the coating layer with a height of at least three layers.

  • Publication number: 20240142664
    Abstract: Two types of blue light blocking contact lenses are provided and are formed by curing different compositions. The first composition includes a blue light blocking component formed by mixing or reacting a first hydrophilic monomer and a yellow dye, a first colored dye component formed by mixing or reacting a second hydrophilic monomer and a first colored dye, at least one third hydrophilic monomer, a crosslinker, and an initiator. The first colored dye includes a green dye, a cyan dye, a blue dye, an orange dye, a red dye, a black dye, or combinations thereof. The second composition includes a blue light blocking component, at least one hydrophilic monomer, a crosslinker, and an initiator. The blue light blocking component is formed by mixing or reacting glycerol monomethacrylate and a yellow dye. Further, methods for preparing the above contact lenses are provided.

  • Patent number: 11301198
    Abstract: A method for information display, a processing device, and a display system are disclosed. The display system includes a light transmissive display screen, at least one first information extraction device, at least one second information extraction device, and a processing device. The processing device is connected to a display screen, the first information extraction device, and the second information extraction device. The first information extraction device extracts position information of a user. The second information extraction device extracts position information of a target object. The processing device constructs a fixed reference coordinate system, locates initial positions of the user, the target object, and the display screen, accordingly displays a fused image on the display screen, and updates the fused image displayed on the display screen according to at least one of a movement amount of the display screen and a movement amount of the user.
