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

Claim 19:
20. A semiconductor device comprising:
a semiconductor layer that has a main surface;
an electrode pad that is formed on the main surface;
a rewiring that is connected to the electrode pad and that is formed on the main surface such as to be drawn out to a region outside the electrode pad;
a post electrode having a first electrode surface connected to the rewiring, a second electrode surface positioned on a side opposite to the first electrode surface, and an electrode lateral surface that connects the first electrode surface and the second electrode surface together and that is roughened; and
a resin that exposes the second electrode surface on the main surface and that seals the rewiring and the post electrode such as to cover the electrode lateral surface.
