Abstract

A RESISTOR COMPRISING A SUBSTRATE (21) TYPICALLY MADE OF ALUMINUM, A PAIR OF TOP ELECTRODE LAYERS (22) MADE OF A THIN NOBLE METAL FILM DISPOSED ON BOTH ENDS OF THE TOP FACE OF THE SUBSTRATE (21), AND A RESISTANCE LAYER (24) OF A THIN METAL FILM MADE OF NI SYSTEM OR CR SYSTEM DISPOSED ON THEIOP , FACE OF THE SUBSTRATE (21) SO AS TO ELECTRICALLY CONNECT WITH THE TOP ELECTRODE LAYER. THE MOISTURE ABSORBENCY OF A PROTECTIVE LAYER (25, 26) IS REDUCED TO UPGRADE SEALING OF THE RESISTANCE LAYER (24) BY COVERING THE RESISTANCE LAYER (24) WITH TWO RESIN LAYERS: A FIRST PROTECTIVE LAYER (25) MADE OF POLYIMIDE RESIN AND A SECOND PROTECTIVE LAYER (26) MADE OF EPOXY RESIN, WHICH HAVE DIFFERENT WATER VAPOR PERMEABILITY, TO IMPROVE THE RELIABILITY, PARTICULARLY THE MOISTURE RESISTANCE CHARACTERISTICS, OFTHE RESISTOR.FIGURE 1.
