PURPOSE:To achieve transfer securely and stably by supplying a tape which nearly crosses the surface of a heat sink at right angle to the surface to be die-bonded, allowing a wax material of the tape to oppose to the surface to be die-bonded, and applying the wax material of the tape to the surface to be die-bonded opposing to the die-bond surface. CONSTITUTION:A tape 40, where a wax material is adhered, is supplied to a surface to be die-bonded 21 which is upright to the surface of a heat sink 10 from the direction which is nearly at right angle to the surface of the heat sink 10. Thus, even if the surface to be die-bonded 21 is surrounded by the terminal part of a large number of electrifying lead pins 30, the wax material can be transferred to the surface to be die-bonded 21 without any difficulty. Also, even if a flat surface exists at the upper position from the surface to be bonded 21 at the side of the surface to be die-bonded 21, only the wax material at a specified part of the tape 40 can be securely transferred and the wax material other than that part is not peeled off the base of the tape 40.
