    • Provided is a method of fabricating a T-type gate including the steps of: forming a first photoresist layer, a blocking layer and a second photoresist layer to a predetermined thickness on a substrate, respectively; forming a body pattern of a T-type gate on the second photoresist layer and the blocking layer; exposing a predetermined portion of the second photoresist layer to form a head pattern of the T-type gate, and performing a heat treatment process to generate cross linking at a predetermined region of the second photoresist layer except for the head pattern of the T-type gate; performing an exposure process on an entire surface of the resultant structure, and then removing the exposed portion; and forming a metal layer of a predetermined thickness on an entire surface of the resultant structure, and then removing the first photoresist layer, the blocking layer, the predetermined region of the second photoresist layer in which the cross linking are generated, and the metal layer, whereby it is possible to readily perform a compound semiconductor device manufacturing process, and to reduce manufacturing cost by means of the increase of manufacturing yield and the simplification of manufacturing processes.
    • 提供一种制造T型栅极的方法,包括以下步骤:分别在衬底上形成预定厚度的第一光致抗蚀剂层,阻挡层和第二光致抗蚀剂层; 在所述第二光致抗蚀剂层和所述阻挡层上形成T型栅极的主体图案; 暴露第二光致抗蚀剂层的预定部分以形成T型栅极的头部图案,并且进行热处理工艺以在除了T型的头部图案之外的第二光致抗蚀剂层的预定区域处产生交联 门; 在所得结构的整个表面上进行曝光处理,然后去除所述暴露部分; 在所得结构的整个表面上形成预定厚度的金属层,然后去除第一光致抗蚀剂层,阻挡层,产生交联的第二光致抗蚀剂层的预定区域和金属层 ,由此可以容易地进行化合物半导体器件制造工艺,并且通过增加制造成品率和简化制造工艺来降低制造成本。
