Moisture-resistant resistor

Abstract

One embodiment of this disclosure relates to a resistor, including a substrate, a first electrode, a second electrode, and a conductive layer. The first electrode and the second electrode are disposed on the substrate. The conductive layer is disposed on the substrate and electrically connects the first electrode and the second electrode. The substrate has a first gap adjacent to the conductive layer.

Claims
