Abstract: The present invention proposes a resistor with two barrier layers covered by a protection layer, at both sides of the resistor to resist the moisture and sulphide penetration from both sides. The barrier can enhance the anti-corrosion ability of the resister. For a metallic barrier, a distance to the resistance layer and the internal electrode layer is necessary.

Abstract: An ignition resistor comprises a substrate, two antistatic layers, an ignition structure and a protective layer. The ignition structure is attached to the upper surface of the substrate through an adhesive layer, wherein the ignition structure includes two electrode portions and an ignition portion, the two electrode portions are respectively connected to two opposite ends of the ignition portion. The two antistatic layers are respectively disposed on the opposite sides of the ignition portion and the upper surface of the substrate between the two electrode portions, and the protective layer covers the ignition portion.

Abstract: A thin film resistor is provided, and a resistance layer of the thin film resistor is a patternized mesh. The mesh density of the mesh resistance layer increases from center to both ends of the film resistor. The temperature peak is shifted from the center to both ends of the film resistor. Therefore, the heat can be quickly dissipated via the electrodes.

Abstract: The present invention discloses a method for preparing a thin film resistive layer. A tantalum nitride layer is formed on the surface of a substrate by a magnetron sputtering method, then a tantalum pentoxide layer is formed on the tantalum nitride layer by same method. Finally, both the tantalum nitride layer and the tantalum pentoxide layer are treated with an annealing process to obtain the thin film resistive layer with a low resistance change rate.
