    Abstract: The melthod comprises the steps of applying a multi-layer photoresist on a GaAs wafer (101), reduction-transferring a shape of the upper layer of photoresist (109) to the intermediate layer of photoresist (107) and depositing an oxide film (108) transferring a shape of gate to the lower layer of photoresist (105), lateral-etching the photoresist (105) and depositing a tungsten silicide film (113); and forming a T type gate (114), a Si ion implant layer (115), an oxide film (117) and a metallic wire (118).

    Abstract translation: 熔融法包括以下步骤:在GaAs晶片(101)上施加多层光致抗蚀剂,将光致抗蚀剂(109)的上层的形状还原转移到光致抗蚀剂(107)的中间层,并沉积氧化膜(108 )将栅极的形状转移到光致抗蚀剂(105)的下层,横向蚀刻光致抗蚀剂(105)并沉积硅化钨膜(113); 以及形成T型栅极(114),Si离子注入层(115),氧化膜(117)和金属线(118)。
