Abstract:
1. A semiconductor device comprising: a semiconductor substrate having a front surface and a back surface opposite to each other, the front surface having a rectangular shape comprising a first side, a second side opposite to the first side, a third side, and a fourth side opposite to the third side, in a plan view; a first MOSFET having a first gate electrode, a first source region and a first drain region, provided over the front surface; a second MOSFET having a second gate electrode, a second source region and a second drain region provided over the front surface; a first source electrode coupled to the first source region, disposed over the front surface; a second source electrode coupled to the second source region, disposed over the front surface; a first gate line coupled to the first gate electrode, disposed over the front surface; a second gate line coupled to the second gate electrode, disposed over the front surface; a common drain electrode coupled to the first drain region and the second drain region, provided over the back surface, wherein the first source electrode is disposed at the first, second, third and fourth sides of the front surface, wherein the second source electrode is surrounded by the first source electrode at the first, second, third and fourth sides of the front surface in the plan view, wherein the first source electrode overlaps the first MOSFET in the plan view, and wherein the second source electrode overlaps the second MOSFET in the plan view.
