Circular semiconductor device with electrostatic discharge (ESD) device and functional device

摘要

One or more semiconductor devices with an electrostatic discharge (ESD) device and a functional device in a circular arrangement are provided herein. The semiconductor device comprises a first circular sector, a second circular sector, and at least two disconnect regions disposed between the first circular sector and the second circular sector. The first circular sector comprises at least one ESD device. The second circular sector comprises at least one functional device. A single semiconductor device having a circular arrangement or configuration thus has an ESD device and a functional device.
