  • Publication number: 20150109660
    Abstract: Disclosed is a method for fabricating a wavelength conversion device that is capable of suppressing unintended and random polarization reversal due to heating thereby achieving higher wavelength conversion efficiency. The method includes: forming an insulating layer on one place of a crystal substrate naturally and uniformly polarized in a thickness direction; forming an insulating layer pattern with line-and-space by photolithography; then supplying conductive fluid to both planes of the crystal substrate to apply voltage to the crystal substrate, thereby a wavelength conversion device that is periodically polarization-reversed is fabricated. When temperature of the crystal substrate decreases after heating, an ionizer supplies ions to a surface of the crystal substrate, negative ions collect on +z plane, and positive ion collect on ?z plane, thereby unintended and random polarization reversal is suppressed.

    Abstract: A method for preparing a surface modification coating of metal bipolar plates is disclosed, which comprises the following steps: providing a substrate; pre-treating the substrate by processing the substrate, depositing a Ni-layer on the substrate, or a combination thereof, to form an activated layer on the surface of the substrate; packing the substrate in a powder mixture containing a permeated master metal, an activator, and filler powder; and heat-treating the packing to allow the permeated master metal to diffuse into the activated layer and then to form a surface modification coating. The permeation rate of the permeated master metal can be increased due to the activated layer having a high defect concentration. Hence, it is possible to prepare a surface modification coating at a low temperature. The surface modification coating of the present invention can also decrease the interface contact resistance between the bipolar plates and gas diffusion layers.

    Abstract: An exemplary method for manufacturing a circuit board includes, firstly, obtaining an insulating substrate, liquid heat-curable adhesive and electrically conductive particles. The electrically conductive particles are added into the liquid heat-curable adhesive. The electrically conductive particles in the heat-curable adhesive are activated by electrical discharge. Secondly, the liquid heat-curable adhesive having activated electrically conductive particles are spread on the insulating substrate to form a heat-curable adhesive layer on the insulating substrate. Thirdly, the heat-curable adhesive layer are exposed to the mid-infrared light by using a photo-mask, the photo-mask has a pattern corresponding to a desired circuit pattern of the circuit board. The electrically conductive particles relocated themselves one by one to form the circuit pattern under irradiation by the mid-infrared light. Finally, the heat-curable adhesive layer are hardening.

  • Publication number: 20120301669
    Abstract: A method of bonding a metal to a substrate involves forming a plurality of nano-features in a surface of the substrate, where each nano-feature is chosen from a nano-pore and/or a nano-crevice. In a molten state, the metal is over-cast onto the substrate surface, and penetrates the nano-features. Upon cooling, the metal is solidified inside the nano-features, where the solidification of the metal forms a mechanical interlock between the over-cast metal and the substrate.

  • Publication number: 20110212274
    Abstract: According to one embodiment, the method includes providing a substrate containing a metal-containing barrier layer having an oxidized surface layer, exposing the oxidized surface layer to a flow of a first process gas containing plasma-excited argon gas to activate the oxidized surface layer and applying substrate bias power during the exposing of the oxidized surface layer to the flow of the first process gas. The method further includes exposing the activated oxidized surface layer to a second process gas containing non-plasma-excited hydrogen gas, wherein the exposure to the first process gas, in addition to activating the oxidized surface layer, facilitates chemical reduction of the activated oxidized surface layer by the second process gas containing the hydrogen gas. A thickness of the metal-containing barrier layer is not substantially changed by the hybrid in-situ dry cleaning process.
