Abstract
PURPOSE:To reduce operating time and costs by removing n a-Si and a-Si layers located at a display section through a dry process using source and drain electrodes as masks. CONSTITUTION:A gate electrode 12 is formed on a transparent insulating substrate 11, and gate insulating film 13, a-Si layer 14, n a-Si layer 14' and a single-or double-layered metal film (electrode material) are formed in the form of films on the gate electrode 12. Subsequently, source and drain electrodes 15 and 16 are patterned using a photolithographic technique, and n a-Si layer 14' and a-Si layer 14 located at an indication part are removed by a dry process using the electrodes 15 and 16 as masks. After that, display electrode 17, source electrode 15 and drain electrode 16 are formed and the n a-Si layer 14' exposed at a channel part is removed by a dry process to form a surface protecting film 18. Thus, a thin film transistor 19 is obtained.
