Abstract
본 발명은 평판용 디스플레이의 COG 구조에 관한 것으로 패널의 패턴부분은 유리기판 상에 형성된 ITO위에 알루미늄이 증착되고 상기 알루미늄 전체를 크롬막으로 도포한 뒤 본딩될 부위만을 에치시켜 와이어가 본딩될 부위만 알루미늄막의 표면이 드러나도록 패터닝시키고, 회로패턴 부분은 글라스 상에 알루미늄을 증착하고 그 위에 다시 크롬막을 상기와 동일한 방법으로 증착시키고 와이어가 본딩될 부위만 알루미늄막이 드러나도록 상기 크롬을 식각시킨뒤, 칩 전극과 상기 노출된 알루미늄막을 금(Au) 및 알루미늄(Al) 와이어로 본딩시키므로써, 알루미늄막의 긁힘 및 산화를 방지할 수 있을 뿐 아니라 단선이나 저항이 변화되는 것을 줄일 수 있는 고신뢰성의 COG 패널 층 구조를 실현할 수 있게 된다.The present invention relates to a COG structure of a flat panel display, wherein the pattern portion of the panel is deposited on ITO formed on a glass substrate, and the entire aluminum is coated with a chromium film, and only the portion to be bonded is etched by etching only the portion to be bonded. The surface of the aluminum film is patterned so that the surface of the aluminum film is exposed, the circuit pattern portion is deposited with aluminum on the glass, and the chromium film is deposited thereon in the same manner as above, and the chromium is etched so that only the portion where the wire is to be bonded is exposed. Bonding the electrode and the exposed aluminum film with gold (Au) and aluminum (Al) wires, a highly reliable COG panel layer that not only prevents scratching and oxidation of the aluminum film but also reduces disconnection or resistance change The structure can be realized.
