Abstract:
1. A method of forming a semiconductor device comprising: forming doped regions of the semiconductor device in a device shape having a first perimeter that has a first length on a surface of a semiconductor substrate and having a first area; and arranging the doped regions to form the device shape that is selected from the group consisting of a shape that is a three sided polygon wherein the first length is no less than 1.6 times a first distance around a circumference of a circle having the first area, a four sided polygon wherein the first length is no less than 2.5 times the first distance, a five sided polygon wherein the first length is no less than 1.5 times the first distance, a shape wherein at least one side is curved and the first length is no less than 1.5 times the first distance, and a convex polygon of seven or more sides wherein the first length is no less than 1.5 times the first distance.
