摘要： A method for manufacturing a TFT panel of an LCD device includes the steps of wet etching a multilayer metallic structure including a high-melting-point metal film (HMPM) film, Al film and another HMPM film while using side etching technique by using a photoresist mask, hot-water washing the side walls of the Al film after the wet etching, and dry etching for configuring the channel region of a TFT in each pixel, and removing the photoresist mask. The presence of the photoresist mask and the protection film prevents corrosion of Al caused by plasma of the etching gas in the dry etching.

摘要： A liquid crystal display panel of the type having reflection electrodes tends to have an image-forming plane undesirably yellowed due to the wavelength dependency of transparency observed in an orientation layer on the reflection electrodes; aluminum-neodymium alloy, which has neodymium content between 5 weight % to 10 weight %, is deposited on an inter-layered insulating layer at the substrate temperature equal to or less than 170 degrees in centigrade for the reflection electrodes so that the surface morphology is represented by average pitches equal to or less than 1 micron; even though the orientation layer has the wavelength dependency of transparency, the reflection electrodes make the optical path in the orientation layer equalized so that the image-forming plane is not yellowed.

摘要： A liquid crystal display is fabricated which has bus wires disposed in a grid shape, switching elements coupled to the bus wires, and pixel electrodes which are disposed on an interlayer insulating film formed by coating and which are coupled with the switching elements. In fabricating the liquid crystal display, when a transparent conductive film is formed on the interlayer insulating film which is formed by coating, the temperature of the substrate is controlled to become 100° C.-170° C. In another embodiment, when the transparent conductive film is formed on the interlayer insulating film in a non-heated condition, an oxygen flow rate ratio is set to 1% or lower, and annealing is performed after forming the film. Thereby, when etching the ITO film on the interlayer insulating film, etching residue is not produced. Further, contact resistance between the ITO film and the lower layer metal can be uniformly decreased, and display defects can be obviated.

摘要： In a method of forming an electrically conductive lamination pattern, an insulating film is formed on a surface of a chromium-containing bottom layer, before an aluminum-containing top layer is formed over the insulating film, so that the insulating film separates the aluminum-containing top layer from the chromium-containing bottom layer. A first selective wet etching process is carried out for selectively etching the aluminum-containing top layer with a first etchant. A second selective wet etching process is carried out for selectively etching the chromium-containing bottom layer with a second etchant in the presence the insulating film which suppresses a hetero-metal-contact-potential-difference between the chromium-containing bottom layer and the aluminum-containing top layer during the second selective wet etching process.
