Assignee: ROHM CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a first lead;
a semiconductor element mounted on the first lead and having an element obverse surface and an element reverse surface that are spaced apart from each other in a thickness direction, the semiconductor element including: an electron transit layer that is disposed closer to the element obverse surface than to the element reverse surface and is formed of a first nitride semiconductor; an electron supply layer that is disposed between the electron transit layer and the element obverse surface and is formed of a second nitride semiconductor different from the first nitride semiconductor; a gate electrode; a first electrode and a second electrode that are disposed on the element obverse surface and include a first connecting portion and a second connecting portion, respectively, that are electrically connected to the electron supply layer and are separated from each other with the gate electrode intervening therebetween in a cross-sectional view; a third electrode disposed on the element reverse surface and bonded to the first lead;
a second lead electrically connected to the second electrode and configured to pass an electric current subjected to switching between the first electrode and the second electrode based on control by the gate electrode; and
a connecting member that electrically connects the first electrode and the third electrode to each other, the connecting member including a first end bonded to the first electrode and a second end bonded to the first lead,
wherein the second end is placed near a semiconductor element mounting portion of the first lead.
