Abstract
An array of power transistors on a semiconductor chip has serpentine gates separated by alternating source and drain regions. The gates combine rounded ends and rectangular sections joining the rounded ends. This geometry allows the metallization, in which the upper and lower metal layers are substantially congruent with each other, to have a design width that can be increased or decreased with the changes in width matched by the length of the rectangular sections thus allowing flexibility in the design of the power transistors.
