Title: Film carrier and liquid crystal display device using it
Inventor: TSUTSUMI KAORI
IPC: G02F1/1345
Filed: 1995-05-26
Abstract: PURPOSE: To provide a film carrier which hardly causes damages in lead wires and to obtain high reliability for connection by forming lead wires on the input side of the carrier in such a manner that the width of the lead on the outer edge is larger than other leads and that the width of the lead on the outer edge in the driving IC side is made larger than the width of the lead itself on the input side. CONSTITUTION: A rectangular driving IC 321 is mounted on a flexible substrate 311 comprising a polyamide resin, and the input side of the carrier is identified by this driving IC 321 from the output side. A pair of input leads 341a, 341b on the outer edges in a group 341 of lead wires for a film carrier 300-1 or the like are made wider by 3 times or more than other leads. Especially, these leads are formed in such a manner that the lead width LB on the back end of the input leads 341a, 341b, where leads are easily cut is made larger, such as by twice or more, than the lead width LA on the front end. Thereby, fracture in the input lead group 341 of a film carrier 300-1 or the like can be effectively prevented.

IPC: H01L21/60
Filed: 1983-07-15
Abstract: PURPOSE:To obtain a wiring, dimensional accuracy thereof is high and resistance thereof is low, by forming the wiring on a package substrate by a multilayer wiring consisting of chromium and copper. CONSTITUTION:A wiring 4 is formed as three layer thin-film multilayer wirings consisting of a chromium layer 10 formed on a package substrate 1 after sintering through the evaporation of a thin-film, a copper layer 11 evaporated on the layer 10 in a thin-film shape and a chromium layer 12 evaporated on the layer 11 in the thin-film shape. A pedestal section 5 is composed of a copper layer 13 evaporated on the chromium layer 12 as the uppermost layer of the wiring 4 in the thin-film shape and a chromium layer 14 evaporated around the copper layer 13 in the thin-film shape. Since the wiring 4 is formed by the three layer thin- film evaporated layers of the chromium layer 10, the copper layer 11 and the chromium layer 12, the wiring 4 and the pedestal section 5 are formed with dimensional accuracy higher than a tungsten wiring formed through sintering. Accordingly, a large-sized pellet can be face-down bonded, and the resistance of the wiring 4 can be lowered by the presence of the copper layer 11.
