    摘要: A thin-film transistor of the reversed stagger type is provided with a gate electrode, first and second gate insulating films, a semiconductor layer, separated contact layers, and source electrodes and drain electrodes, all of which are stacked on a substrate. Upon manufacturing the thin-film transistor of this type, a gap section is pattered in a single contact-material layer. In this case, the contact-material layer is patterned by a dry etching with etching gases including HCl+SF6 or CF4+O2+HCl by the use of the source electrode and drain electrode as direct masks. Upon patterning a gap section in the contact-material layer between the source electrode and the drain electrode, no dedicated resist pattern is required; therefore, it is possible to reduce the number of the processes as compared with conventional manufacturing methods. Consequently, it becomes possible to reduce the production cost of thin-film transistors and also to improve the yield of desired products.

Upon manufacturing the thin-film transistor of this type, a gap section is pattered in a single contact-material layer. In this case, the contact-material layer is patterned by carrying out etching by the use of the source electrode and drain electrode as direct masks or by the use of a resist pattern that was used for forming the respective electrodes. Upon patterning a gap section in the contact-material layer between the source electrode and the drain electrode, no dedicated resist pattern is required; therefore, it is possible to reduce the number of the processes as compared with conventional manufacturing methods. Consequently, it becomes possible to reduce the production cost of thin-film transistors and also to improve the yield of desired products.
