Abstract: PURPOSE:To prevent an active layer surface from being affected by the stress of an insulating film, and reduce parasitic capacitance of a gate electrode, by eliminating the whole part of a first insulating layer between the facining surfaces of a source electrode and a drain electrode, after an aperture is formed in a second insulating layer by using a mask wherein a window having a desired gate length is formed in a resist layer. CONSTITUTION:A photo resist layer 6 in which a window 6a is formed is used as a mask. By an RIE method, a second insulating film 5 is etched to form an aperture 5a. The second insulating film 5 is used as a mask, and ammonium fluoride solution is used through the aperture 5a. Thereby the whole part of a first insulating film 4 which is on an active layer 2 and between the vertical surfaces containing the facing surfaces of a source electrode 3s and a drain electrodes 3d is etched and eliminated. Metal for a gate electrode, e.g. Ti/Pt/Au, is evaporated, and a T-type gate electrode 7 is formed by a lift-off method. Thereby parasitic capacitance which is generated between the gate electrode and the active layer can be restricted within a small range.
