Abstract:
1. A method for manufacturing a semiconductor integrated circuit device, comprising the steps of: (a) forming an on-chip rewiring pattern in each chip region over a device surface of a semiconductor wafer having a plurality of chip regions, and a scribe region therebetween, and forming a test rewiring pattern electrically coupled to an aluminum type pad electrode in the scribe region; (b) after the step (a), forming an organic type insulation film almost entirely over the device surface including the surface of the on-chip rewiring pattern; (c) forming a bump forming opening in the organic type insulation film over the on-chip rewiring pattern; (d) forming a bump electrode over the on-chip rewiring pattern at the bump forming opening; (e) after the step (d), carrying out a laser processing on the scribe region, and thereby removing the test rewiring pattern and the aluminum type pad electrode; and (f) carrying out a dicing processing using a rotary blade on the region subjected to the laser processing, and thereby separating the semiconductor wafer into respective chip regions, wherein upon completion of the step (d), the organic type insulation film forms an integral film pattern covering almost the entire region of the chip regions except for the bump forming opening, and almost the entire region of the scribe region.
