Semiconductor device |
| abstract |
The present invention provides a semiconductor device capable of suppressing an increase in on-resistance by suppressing a reduction in the area of an effective region of an active region and suppressing a growth of a stacking fault generated when a forward current flows in a body diode. To do. A semiconductor substrate 10 made of silicon carbide is provided with first and second cells 101a and 101b having a MOS gate structure. The first cell 101a is a normal MOSFET cell. In the second cell 101 b, the gate electrode 8 b is directly connected to the source electrode 14 and fixed to the potential of the source electrode 14. The second cell 101b is configured such that the surface potential of the p-type channel region of the second cell 101b is lower than the surface potential of the p-type channel region of the first cell 101a when the first cell 101a negatively biases the gate electrode 8a. The thickness t1b of the gate insulating film 7b is set to be thinner than the thickness t1a of the gate insulating film 7a of the first cell 101a. [Selected figure] Figure 1 |
