IPC: H01L21/822
Filed: 2000-06-02
Abstract: PROBLEM TO BE SOLVED: To solve the problem of increased number of processes to form a contact hole in an insulation film simply by using a PR process, in order to form a thin-film shunt transistor, and although, as the method of connecting its gate wiring and its source/drain wiring with each other without using any PR process, the method of the short-circuiting of the two wirings by a laser is considered, there is generated a faultiness wherein the gate wiring of the portion irradiated by the laser is also removed therefrom to bring a disconnection. SOLUTION: In a manufacturing method of a thin-film transistor, there is used the structure that a transparent metallic film 2 and a low-resistance metallic film 3 are necessarily laminated in one wiring of the two wirings present in a laser-welded place, and the one wiring is made to overlap with the other wiring provided oppositely to it via an insulation film 5. As a result, no disconnection is generated even in the case of any laser welding and by scanning a laser beam 9 a plurality of welded places can be welded with the laser scanning of only one time.
