  • PLASMA ETCHING METHOD AND PLASMA ETCHING DEVICE
    Publication number: 20240096596
    Abstract: The present invention introduces a plasma etching method and apparatus. The plasma etching method may include forming a photoresist pattern on a target etching layer, hardening the surface of the photoresist pattern by exposing to a first plasma generated from a first discharge gas containing a reforming gas including carbon (C) and sulfur (S) and sequentially annealing, and etching the target etching layer with a second plasma generated from a second discharge gas using the surface-hardened photoresist pattern as a mask.

  • Roll joint
    Patent number: 11833672
    Abstract: A roll joint is provided. The roll joint may comprise: a first body; a second body disposed opposite to and spaced apart from the first body; a connection body which is disposed between the first body and the second body and is not in contact with the first body and the second body; and a connection wire member which connects the first body, the second body, and the connection body to one another so as to make a tensegrity structure.

  • Metal oxide coated phosphor for plasma display panel and manufacturing method thereof
    Publication number: 20060210791
    Abstract: The present invention relates to a phosphor for a plasma display panel and a method for producing the same. The phosphor is formed by coating a metallic oxide having a high polarity to a surface of a green phosphor Zn2SiO4:Mn with a thickness 10 nm to 0.5 ?m. The concentration of a metallic oxide is in a range of 1 to 50 weight % with respect to the green phosphor. According to the green phosphor for the plasma display panel of the present invention, which is made with coating, a metallic oxide having a positive polarity to a surface of a phosphor can be adjusted, thereby enhancing the discharge characteristics when the panel is driven.
