Abstract

The density of a transistor array is increased by forming one or more deep trench isolation structures in a semiconductor material. The deep trench isolation structures laterally surround the transistors in the array. The deep trench isolation structures limit the lateral diffusion of dopants and the lateral movement of charge carriers.
