摘要
There is provided a high electron mobility transistor (HEMT) and the production method. Devices in accordance with embodiments of the invention include an aluminum gallium nitride (AlGaN) barrier layer on the gallium nitride (GaN) channel layer and the channel layer. Is provided with a first ohmic contact on the barrier layer 16 is formed a source electrode 18, a second ohmic contact is also provided to be spaced apart from the source electrode 18 is formed with a drain electrode 20. A GaN based cap segment (30) is provided on the barrier layer 16 between the source electrode 18 and drain electrode 20. GaN based cap segment 30 may have a spaced apart from the source electrode 18 has a first side wall adjacent to (31) are spaced apart from the drain electrode 20 adjacent to the second side wall (32). On the GaN based cap segment 30, a non-ohmic contact is provided to form a gate contact (22). Gate contact (22) has a first side wall 31 and substantially the first side wall (27) aligned in a GaN based cap segment 30. Gate contact 22 is only part of the height distance between the first side wall 31 and the second side wall 32 of the GaN-based cap segment 30.
