Abstract
A layout structure of electrostatic discharge (ESD) protection circuit cooperated with an ESD protection device includes a first electrically conductive layer and a second electrically conductive layer. The first electrically conductive layer is disposed on the ESD protection device and electrically connected to the ESD protection device. The second electrically conductive layer is disposed on the first electrically conductive layer and electrically connected to the first electrically conductive layer. A width or a projection area of the second electrically conductive layer is less than that of the first electrically conductive layer.
