Abstract: PURPOSE: A field effect transistor and a method for fabrication the same are provided to improve productivity and stability by not using a lithography process. CONSTITUTION: An active layer(31), a cap layer(32), an ohmic metal layer(33) and an insulating layer(34) are formed on a substrate(30). An insulating layer is etched by using a photoresist pattern as an etching mask. A metal is deposited on a gate recess region(37c) and the insulating layer to form a gate-electric field electrode layer(39).
