Abstract
An electronic device includes an ESD protection device with implanted regions that extend around a finger shape with a straight portion and elongated turn portions, and contacts that extend only in the straight portion, where the turn portions include elongated lightly doped implanted regions to mitigate turn on of a curvature PNP transistor for uniform device breakdown performance. Adjacent finger structures are spaced apart from one another to mitigate thermal transfer between device fingers.
