Title: Methods for fabricating a pseudomorphic high electron mobility transistor
Inventor: LIM JONG WON
IPC: H01L29/778
Filed: 2007-03-06
Abstract: A method for fabricating a pseudomorphic high electron mobility transistor is provided to reduce capacitance between a gate and a source and between a gate and a drain by leaving a passivation layer only in a partial region under the head of a gate electrode. Source and drain electrodes(12a,12b) are formed on a substrate(11) having an epitaxial growth layer. A passivation layer is formed on the resultant structure. After a first photoresist layer is formed on the passivation layer, the first photoresist layer and the passivation layer are patterned to expose the upper portion of the substrate by using a mask pattern. After the first photoresist layer on the passivation layer is removed, a second photoresist layer having a fine pattern narrower than the pattern of the passivation layer is formed on the resultant structure. After the remaining passivation layer is etched, the second photoresist layer is removed. After a third photoresist layer of a multilayered structure is formed on the resultant structure, the third photoresist layer is patterned to form a gate electrode(20) of a T shape. The upper portion of the substrate is etched by using the passivation layer etched by the fine pattern to form a recess in the upper surface of the substrate. After metal for a gate electrode is deposited on the resultant structure, the third photoresist layer and the metal for the gate electrode are removed to form a gate electrode of a T shape connected to the substrate by the recess.
