Semiconductor device and method of manufacturing the same

Abstract

When manufacturing a semiconductor device by mounting a semiconductor chip 2 on a substrate 1 with a flip-chip method, projections 9 are formed between pads 4 arranged in multiple annular concentric layers on the semiconductor chip 2 other than pads 4 arranged along the innermost periphery thereof. On the substrate 1, bonding resin 3 is dispensed onto an area inside the innermost periphery along which the pads 4 are arranged. By heating and applying pressure, the bonding resin 3 is spread over the entire gap between the substrate 1 and the semiconductor chip 2 so as to secure the substrate 1 to the semiconductor chip 2 by the bonding resin 3, thereby preventing a void from being formed in an area outside the innermost periphery along which the pads 4 are arranged and thus stabilizing an electrical connection state between the semiconductor chip 2 and the substrate 1.
