  • Patent number: 7237324
    Abstract: A multiple chip resistor is manufactured in the following method. First electrode layers are formed on a first surface of a substrate. Resistor elements electrically connected to the first electrode layers, respectively, are formed on the first surface of the substrate. Slits are formed in the substrate for separating the first electrode layers. Edge electrodes connected to the first electrode layers at the edges of the slits, respectively, are formed on respective edges at the slits of the substrate. The substrate is divided at the slits into strip substrates. Portions of the edge electrodes are removed for electrically isolating the resistor elements from each other. The method provides the edge electrodes on each strip substrate with an improved dimensional accuracy, hence allowing the edge electrodes to be isolated electrically from each other. Consequently, the multiple chip resistor is prevented from being mounted defectively when the resistor is surface-mounted.
