A wafer level chip scale package is provided to induce the crack generated in a solder joint to a sacrificial metal layer by mounting a wafer level chip scale package on a module substrate so that a semiconductor chip module can be constructed. A semiconductor chip includes a bonding pad. A first insulation layer is formed on the semiconductor chip to expose the bonding pad. A redistribution line is formed on the exposed bonding pad and the first insulation layer. A sacrificial layer(230) is formed under a redistribution pad of the redistribution line. A second insulation layer is formed on the redistribution line to expose the redistribution line, including a crack inducing hole(245) formed at the side of the sacrificial layer. An external connection terminal is attached to the redistribution pad. The sacrificial layer can include a solder. The crack inducing hole can have a polygonal structure surrounding a partial surface of the external connection terminal.
