  • Patent number: 7312152
    Abstract: The corrosion of aluminum-based metal films may be minimized by applying a lactate-containing solution to the aluminum-based metal films before the aluminum-based metal films are etched. The lactate-containing solution is applied to the aluminum-based metal film before the film is etched with a corrosive etchant. Minimizing the corrosion of the aluminum-based film may increase the yield and performance of the highly reflective pixel arrays that are formed from the aluminum-based metal for use in liquid crystal on silicon (LCOS) microprocessors for digital televisions.

  • Patent number: 7312111
    Abstract: An LCD panel includes a plurality of gate lines and gate electrodes formed on a substrate and a gate insulating film formed on the substrate including the gate lines and the gate electrodes. A semiconductor film is formed in a region on the gate insulating film and an ohmic contact film formed on the semiconductor film. A plurality of data lines cross the gate lines; a source electrode is formed on the ohmic contact film; and a pixel electrode is formed in a pixel region defined by the gate and data lines. A drain electrode is formed on the ohmic contact film, and has an uneven width. Since a portion of drain electrode that overlaps with the gate electrode has a smaller width than a width of other portions of the drain electrode, variation in an area of the drain electrode overlapped with the gate electrode is small, so that variation of the parasitic capacitance can be reduced, thereby improving picture quality.

  • Patent number: 7304383
    Abstract: There are provided a TFT substrate for an LCD apparatus and a method of manufacturing the same. A substrate (10), a diffusion barrier layer (11) and a copper alloy layer (12) are formed on the TFT substrate, consecutively. The copper alloy includes a material from about 0.5 at % to about 15 at % to form a gate wiring layer. The material is used to form the diffusion barrier layer (11). A compound that comprises a material such as Zr, Ti, Hf, V, Ta, Ni, Cr, Nb, Co, Mn, Mo, W, Rh, Pd, Pt, etc. is deposited on the diffusion barrier layer (11) to a thickness from about 50 ? to about 5,000 ?. The deposited compound is then heat treated to convert the deposited compound into a silicide compound (11b). The transistor substrate has low resistance and high conductance. Also, etching process is simplified, and a mutual diffusion is prevented by means of the thin diffusion barrier layer.
