  • Patent number: 11675273
    Abstract: Provided is a method of fabricating a micro-nano structure, including: forming a reflective layer and a fluid polymer layer sequentially on a surface of a substrate; pressurizing the substrate and a mask having a micro-nano pattern to attach to each other, squeezing the fluid polymer layer into a light-transmission area of the mask, and curing the fluid polymer layer; and exposing, wherein a fluid polymer in the light-transmission area is configured to sense light under a combined effect of a transmitted light and a light reflected by the reflective layer, such that a micro-nano structure is obtained. The method solves the problem of limited diffraction, improves the processing resolution by reducing the transmission loss of evanescent waves through reflective light field enhancement, and reduces the difficulty and cost of mask processing and pattern defects by using shallow pressurizing in combination with exposure.

  • Patent number: 8696344
    Abstract: A molding method includes: drawing cross-section elements of a three-dimensional object as a molding target on a drawing surface of a drawing stand with a liquid whose curing is precipitated by receiving activation energy as cross-section patterns; applying the activation energy to the liquid configuring the cross-section patterns in a state in which the cross-section patterns is pinched between the drawing stand and a molding stand; and detaching the cross-section patterns after being applied with the activation energy from the drawing stand and transferring the cross-section patterns to the molding stand side, wherein the drawing surface has a liquid repellent area that is an area representing liquid repellency for the liquid and a lyophilic area that is independently formed in an island shape within the liquid repellent area and is an area representing lyophillicity stronger than that of the liquid repellent area for the liquid.

  • Publication number: 20140090769
    Abstract: An electronic device may have structures such as housing structures, display structures and other device structures that form gaps when assembled. To prevent intrusion of moisture and other environmental contaminants, the gaps may be filled using gap sealing material. The gap sealing material may be a liquid polymer that is applied to the gap in a way that creates an excess protruding portion. Light-based processing techniques and application of solvent may be used to remove excess material. A sealing material such as an adhesive may be applied to gaps to forming a sealing structure. A material may be applied to the adhesive sealing material to cause the sealing material to expand and fill the gap. An undersized gasket may be placed in a gap. The gasket may include materials such as polymer that expands upon application of moisture.
