Chip resistor

The integrated circuit (IC) chips in modern electronic devices include circuits, such as mixed signal circuits, RF circuits, and power amplifier circuits, that require accurate and stable voltages to operate properly. To obtain stable voltages, the circuits in an IC chip, in turn, require components, such as resistors, that remain stable under diverse operating conditions. Recently, a demand for miniaturization or dimensional reduction of electronic devices is more and more increasing, and as a result, very small-sized chip electronic components are increasingly employed as electronic components. Under this circumstance, high precision chip resistors have been demanded as alternatives to conventionally used trimming volumes. In particular, the demand for chip resistors having a low resistance and a small temperature coefficient of resistance used in a power supply circuit has been increased. A typical chip resistor may include a small, rectangular supporting substrate on which a resistor layer having a required resistance is formed together with two terminal electrodes connected to the resistor layer. For protection of the resistor layer, a protective coating is formed on the substrate to cover the resistor layer. Chip resistors are generally produced by forming a resistive layer on the surface of an insulating substrate, providing electrodes at both ends of the resistive layer, and forming one or more protective films on the surface of the resistive layer.
