Semiconductor protection devices with high area efficiency

Abstract

Semiconductor devices with high area efficiency are described. Such a semiconductor device can be positioned within an isolation structure, and include diodes coupled to the isolation structure. In this manner, the semiconductor devices utilize an area, which may be otherwise left as an inactive space (or dead space) to achieve a smaller footprint. Further, the semiconductor devices may include multiple fingers of doped regions arranged horizontally, vertically, or a combination of both. The fingers of doped regions form diodes connected in parallel using metal lines that are parallelized to facilitate flowing large amounts of current. The parallelized metal lines with reduced lengths ameliorate issues associated with parasitic resistance of the metal lines during ESD or surge events.
