Abstract:
1. A method of fabricating a semiconductor device, comprising the steps of: forming a resin layer on a principal surface of a semiconductor substrate carrying thereon a plurality of bump electrodes, such that said resin layer seals said principal surface of said semiconductor substrate, said bump electrodes projecting from a main surface of said resin layer in a direction away from said semiconductor substrate; grooving said resin layer along a dicing line on said semiconductor substrate by a first blade having a first blade width, to form a groove such that said groove penetrates through said resin layer and reaches said semiconductor substrate; and dicing, after said step of grooving, said semiconductor substrate along said groove by a second blade having a second blade width smaller than said first blade width, such that said semiconductor substrate is divided into individual semiconductor chips.
