Abstract
An over-voltage protection device includes a substrate, an insulation layer having a depression over the substrate, a conductor layer having a first electrode and a second electrode over the insulation layer, wherein the first electrode and the second electrode form a discharge path, and the depression is under the discharge path. A method for preparing the over-voltage protection device includes the steps of forming an insulation layer over a substrate; forming a depression in the insulation layer; forming a photoresist pattern filling the depression and protruding the insulation layer; forming a conductor layer over the insulation layer; and removing the photoresist pattern, wherein the photoresist pattern divides the conductor layer into a first electrode and a second electrode that form a discharge path, and the depression is under the discharge path after the removal of the photoresist pattern.
