Abstract: A plasma etching method using a Faraday cage, comprising: providing a Faraday cage having a mesh portion on an upper surface thereof in a plasma etching apparatus; providing a quartz substrate having a metal mask with an opening provided on one surface of the metal mask in the Faraday cage; and patterning the quartz substrate with plasma etching.

Abstract: The present invention relates to a method of welding an electrode tab which welds an electrode tab and a current collecting layer by using a pulsed laser beam, and a cable type rechargeable battery including an electrode manufactured according to the same.

Abstract: A method for patterning a lithium metal surface, including the steps of (S1) forming an intaglio or relief pattern having a predetermined size on a patterning substrate; (S2) either (a) compressing lithium metal physically to a surface of the patterning substrate having the pattern formed thereon to form the predetermined pattern on the surface of the lithium metal, or (b) applying liquid lithium to the surface of the patterning substrate having the pattern formed thereon and solidifying the liquid lithium to form the predetermined pattern on the surface of the lithium metal; and (S3) separating the lithium metal having the predetermined pattern formed thereon from the patterning substrate, wherein the patterning substrate is at least one selected from a silicon wafer or polycarbonate substrate.

Abstract: Disclosed are a method for forming a pattern for liquid crystal orientation of a zenithal bi-stable liquid crystal panel, a liquid crystal orientation substrate including the pattern formed thereby, and a mask substrate used for forming the pattern.
