Thermosensitive chip for composite electrode

Abstract

A thermosensitive chip for a composite electrode is provided, including a thermosensitive substrate, wherein each of the two surfaces of the thermosensitive substrate is sequentially provided thereon with a silver electrode and a gold electrode from the inside to the outside in a stacked manner. The thermosensitive chip is suitable for the gold wire bonding technology, the gold electrode on the outer surface thereof facilitates better bonding with a gold wire, and the silver electrode on the bottom of the gold electrode can greatly reduce manufacturing costs. In addition, an operation of coating with gold is conducted through a vacuum sputtering machine, so that the manufacturing process is simple and convenient, and the manufacturing effect is good.
