Abstract:
To provide a semiconductor device including a power semiconductor element having improved reliability. The semiconductor device has a cell region and a peripheral region formed outside the cell region. The n type impurity concentration of n type column regions in the cell region is made higher than that of n type column regions comprised of an epitaxial layer in the peripheral region. Further, a charge balance is kept in each of the cell region and the peripheral region and each total electric charge is set so that a total electric charge of first p type column regions and a total electric charge of n type column regions in the cell region become larger than a total electric charge of third p type column regions and n type column regions comprised of an epitaxial layer in the peripheral region, respectively.

Claim (Index 3):
The method of manufacturing a semiconductor device according to  claim 1 ,\n wherein the step (c) and the step (d) are carried out simultaneously; and wherein the width, in the first direction, of the second column regions in the cell region is larger than the width, in the first direction, of the third column regions in the peripheral region.
