  • Patent number: 9293340
    Abstract: A surface planarization method of thin film and a preparing method of an array substrate relate to a display field, and can solve the technical problem that the conventional dry etching severely damages the surface flatness of other film layers below the one being etched, thereby improving the display properties of the LCD. The preparing method of the array substrate comprises patterning a non-metallic layer (4) by a dry etching. And following the step of patterning a non-metallic layer (4) by the dry etching, the method further comprises performing surface planarization on a first film layer (3) to recover the first film layer (3) with a rough surface caused by the dry etching to be planar. The first film layer (3) is located below the non-metallic layer (4).

  • Publication number: 20150360253
    Abstract: Disclosed herein is a thin film patterning method and a thin film patterning apparatus. The thin film patterning method comprises the steps of: disposing a mask above a substrate, wherein the mask is provided with hollow-out parts which are identical with preset deposition patterns; and covering the mask with a thin film, wherein the thin film at hollow-out parts of the mask is formed on the substrate, while the remaining area of the substrate shielded by the mask is free of the thin film, so that a patterned thin film is formed on the substrate. The thin film patterning method in the present disclosure can transfer directly patterns on the mask to the substrate through one-step deposition, omit the process steps of photolithography and etching, simplify the process flow to a large extent, and save the costs of the thin film patterning.
