Abstract:
1. A flip-chip mounting method, comprising, when placing thermosetting underfill resin between a semiconductor chip and a wiring board and flip-chip mounting the semiconductor chip on the wiring board: pressurizing and heating the semiconductor chip positioned with the thermosetting underfill resin placed between the wiring board and the semiconductor chip, from an upside of a tool protection sheet having a two-layer film structure made up of a base film and a pressurizing film; separating the pressurizing film from the tool protection sheet other than a pressurizing portion immediately above the semiconductor chip while curing the underfill resin under the semiconductor chip; and expanding the separated pressurizing film to abut against the underfill resin around the semiconductor chip and cure the underfill resin while pressurizing and heating the underfill resin to fix the semiconductor chip to the wiring board.
