Abstract:
1. A method for manufacturing a semiconductor device, the method comprising: moving a nozzle along a moving track around a semiconductor chip bonded to a wiring substrate by face-down bonding; and continuously supplying underfill material through the nozzle while moving the nozzle along the moving track, thereby filling the underfill material between the wiring substrate and the semiconductor chip, wherein an outline of a surface of the semiconductor chip opposing to the wiring substrate is a polygon composed of a plurality of sides, the moving track of the nozzle includes a plurality of linear tracks, each being within a range of a pair of respective line segments that are perpendicular to a respective one of the plurality of sides, and a non-linear direction changing track that continuously connects adjacent ones of the linear tracks around a corner region of the semiconductor device, and the nozzle is moved slower in at least a portion of the linear track than in the non-linear direction changing track.
