  • Patent number: 7655499
    Abstract: When forming a contact hole by a conventional manufacturing step of a semiconductor device, a resist is required to be formed on almost entire surface of a substrate so as to be applied on a film other than an area in which a contact hole is to be formed, leading to drastically reduced throughput. According to a forming method of a contact hole and a manufacturing method of a semiconductor device, an EL display device and a liquid crystal display device of the invention, an island shape organic film is selectively formed over a semiconductor layer, a conductive layer or an insulating layer, and an insulating film is formed around the island shape organic film to form a contact hole. Therefore, a conventional patterning using a resist is not required, and high throughput and low cost can be achieved.
