IPC: H01L29/08
Filed: 1986-05-19
Abstract: PURPOSE:To reduce a drain conductance and a source resistance by adding very simplified modification of a structure for obtaining ohmic contact. CONSTITUTION:An alloyed region 15A of source electrode 15 is formed deep in an active layer 13 and is sufficiently in contact with a secondary electron gas layer 18. Thereby, a source resistance can be kept small. Moreover, since an alloyed region 16A of drain electrode 16 is formed in such a depth not exceeding a hetero boundary, electron flow to the drain from the source does not flow into the deep region of active layer 13, deviating from the secondary electron gas layer 18. Thereby, drain conductance becomes small, namely gain becomes large.
