Electrostatic discharge protection device and composite electronic component including the same

摘要

Disclosed herein are an electrostatic discharge protection device including: a substrate; a pair of electrodes formed on the substrate so as to be spaced apart from each other; and an insulating layer formed on the electrodes, wherein each of the electrodes has a shape in which it protrudes from a cross section thereof toward a surface thereof, and a manufacturing method thereof, and a composite electronic component including the same.

主权项

1. An electrostatic discharge protection device comprising:
a substrate; a pair of electrodes spaced apart from each other on the substrate and a layer of insulating material on the pair of electrodes, wherein at least one electrode of the pair of electrodes includes a protruding portion, a bottom surface of the protruding portion noncontacing the substrate and covered with the insulating material, and wherein the protruding portion of the at least one electrode of the pair of electrodes is formed as a cone-shaped portion by a photolithography process.
