Abstract:
An enhanced layout for a multiple-finger ESD protection device has several embodiments. In these embodiments, the base contacts of the NPN (or PNP) transistors utilized as voltage clamps in the multiple-finger NPN-based (or PNP-based) multiple-finger ESD protection device are disposed at opposite edges of the multiple-finger ESD protection device and oriented perpendicularly to the orientation of the fingers in the multiple-finger ESD protection device. Similarly, the body contacts of the NMOS (or PMOS) transistors utilized as voltage clamps in the multiple-finger NMOS-based (or PMOS-based) multiple-finger ESD protection device are disposed at opposite edges of the multiple-finger ESD protection device and oriented perpendicularly to the orientation of the fingers in the multiple-finger ESD protection device.
