Abstract
A semiconductor die includes a semiconductor substrate and a transistor array disposed over the semiconductor substrate. The transistor array includes unit cells and spacers. The unit cells are disposed along rows of the transistor array extending in a first direction and columns of the transistor array extending in a second direction perpendicular to the first direction. The spacers encircle the unit cells. The unit cells include source contacts and drain contacts separated by interlayer dielectric material portions. First sections of the spacers contacting the interlayer dielectric material portions are thicker than second sections of the spacers contacting the source contacts and the drain contacts.
