Abstract: PURPOSE:To prevent any protrusion from generating by a method wherein, after an etching is performed in such a way that an opening part is formed on the polycrystalline silicon film, an oxidation is performed on the surface of the polycrystalline silicon film by an anodizing method, and after that, an etching treatment to remove silicon residues remaining in the opening part is performed. CONSTITUTION:A polycrystalline silicon film 3 is coated on an oxide film 2 formed on the surface of a substrate 1. There exist foreign substances 4 in the interior of the polycrystalline silicon film 3 and resist films 5 are patterned on the surface of the film 3. When an etching is performed by a reactive ion etching method, parts of the polycrystalline silicon film 3, which are located under the foreign substances 4, remain on the surface of the oxide film 2 as protrusion parts 6 of a polycrystalline silicon film. For coating an oxide film on the film surfaces of the polycrystalline silicon films 3, the substrate 1 is inserted in a water solution 7 of oxalic acid, the polycrystalline silicon films 3 are set on the positive side, an electrode 8 is set as the negative side, and a DC voltage of 20 volts or thereabouts is impressed by a DC power source 9. By this anodizing, an oxide film 10 is formed on each surface of the polycrystalline silicon films and the protrusion parts 6 of a polycrystalline silicon film are never oxidized as the DC voltage is not impressed on the protrusion parts 6. Accordingly, when an etching is performed on the opening part by an ordinary isotropic etching method, the polycrystalline silicon films 6 in a protruded form are removed.

IPC: H01L29/78
Filed: 1994-07-08
Abstract: PURPOSE:To obviate generation of the connection defects and dropouts of display electrodes and source electrodes even if there are film defects in metallic layers and a developer penetrates into these defects by shortening development time at the time of forming a resist to be made into a mask in the stage of etching the metallic layers. CONSTITUTION:Development is executed by using an aq. soln. of an org. alkaline system as a developer to remove the parts where a photoresist 18 is unnecessary. In such a case, >=95% of the defects are evidently eliminated by setting the development time at 40 or 30sec when the decreasing rate of the number of the defects of the respective finished panels is investigated. The results indicate that developing time is shortened preferably to <=40sec in setting various kinds of the conditions for exposing and developing in order to obtain the prescribed accuracy in patterning using photolithography. As a result, the generation of the defects by a battery effect is suppressed.
