  • Publication number: 20060152127
    Abstract: A display filter is provided that can realize price reduction without lowering electromagnetic wave shielding ability and near infrared rays shielding ability. A conductive mesh is used for shielding electromagnetic waves. A multilayered film and a coloring layer are used for shielding near infrared rays. The multilayered film reflects near infrared rays selectively and the coloring layer absorbs near infrared rays selectively. The use of the multilayered film significantly reduces near infrared rays absorption ability that is required for the coloring layer compared to the case where no multilayered film is used.

  • Patent number: 5578166
    Abstract: The method to etch an electrically conductive film comprises the steps of: forming a metal conductor film comprising copper or copper alloy, upon a substrate; and forming a mask pattern upon the metal conductor film; and etching an exposed part of the metal conductor film by the use of the mask pattern and a reactive ion-etching (RIE) employing a plasma of a gas mixture comprising a silicon tetra-chloride (SiCl.sub.4) gas, a nitrogen (N.sub.2) gas and a carbon compound gas, so that the exposed part of the metal conductor film is removed so as to leave the masked part. The metal conductor film may further comprise a diffusion protection layer formed of a refractory metal or its alloy upon and/or underneath the copper/mainly-copper layer. The mask pattern may be typically formed of silicon dioxide (SiO.sub.2). The substrate may further comprise an insulating layer thereon, typically formed of silicon dioxide (SiO.sub.2), for contacting said metal conductor film.
