摘要：<p>PROBLEM TO BE SOLVED: To easily remove a semiconductor chip having a flip-chip structure. SOLUTION: A semiconductor device comprises a resistor film 2 formed as a heating element on an upper surface of the semiconductor chip 1 mounted on a circuit board 5 via solder bumps 6. A method for removing the semiconductor chip comprises the steps of supplying a current to the resistor film 2 via electrodes 4, and heating the film 2. The method further comprises the step of raising the chip 1 from the board 5 when the heated bump 6 is melted.</p>
