    摘要: Provided is a method for fabricating a field effect transistor. In the method, an active layer and a capping layer are formed on a substrate. A source electrode and a drain electrode is formed on the capping layer. A dielectric interlayer is formed on the substrate, and resist layers having first and second openings with asymmetrical depths are formed on the dielectric interlayer between the source electrode and the drain electrode. The first opening exposes the dielectric interlayer, and the second opening exposes the lowermost of the resist layers. The dielectric interlayer in the bottom of the first opening and the lowermost resist layer under the second opening are simultaneously removed to expose the capping layer to the first opening and expose the dielectric interlayer to the second opening. The capping layer of the first opening is removed to expose the active layer. A metal layer is deposited on the substrate to simultaneously form a gate electrode and a field plate in the first opening and the second opening. The resist layers are removed to lift off the metal layer on the resist layers.

    摘要: A method of fabricating a T-gate is provided. The method includes the steps of: forming a photoresist layer on a substrate; patterning the photoresist layer formed on the substrate and forming a first opening; forming a first insulating layer on the photoresist layer and the substrate; removing the first insulating layer and forming a second opening to expose the substrate; forming a second insulating layer on the first insulating layer; removing the second insulating layer and forming a third opening to expose the substrate; forming a metal layer on the second insulating layer on which the photoresist layer and the third opening are formed; and removing the metal layer formed on the photoresist layer. Accordingly, a uniform and elaborate opening defining the length of a gate may be formed by deposition of the insulating layer and a blanket dry etching process, and thus a more elaborate micro T-gate electrode may be fabricated.
