    摘要: It is an object to downsize a device while maintaining a high breakdown voltage. An external terminal (7) protrudes to the outside from the side wall of a sealing resin (2) and a heat sink (1) is exposed in the bottom of the sealing resin (2). A step surface (21) retracted from the exposed surface of the heat sink (1) is formed in the part of the sealing resin (2) surrounding the periphery of the heat sink (1). When using this semiconductor device, the exposed surface of the heat sink (1) is brought into surface contact with the flat surface (41a) of the radiation fin (41) and an insulation sheet (31) is interposed between the step surface (21) and the flat surface (41a), and which is pressed therebetween. The insulation sheet (31) is disposed to cover the region facing the external terminal (7) in the flat surface (41a). Accordingly, it is possible to set the height of the external terminal (7) from the exposed surface of the heat sink (1) lower than the spatial distance determined on the basis of the rated voltage while keeping the breakdown voltage between the external terminal (7) and the radiation fin (41) as the rated voltage.

    摘要: The present invention relates a semiconductor device, and in particular, it aims at providing a semiconductor device having high reliability by making coating of a region where a gold wire has been used, which has been performed for preventing deformation and breakage of the gold wire in pressure fitting of resin, unnecessary and preventing deformation and breakage of the gold wire without increasing the fabrication cost, in a semiconductor device packaging a power device and a control device controlling this power device. In order to attain the aforementioned object, a mold gate (21) is provided on a molding die (20) employed in fabrication of the semiconductor device to be positioned on a side where a power device (PD) is arranged in a state placing a lead frame (10). While mold resin (MR) is introduced through this mold gate (21), the mold resin (MR) is injected at a fast speed until reaching a region where a gold wire (W2) is arranged and thereafter injected at a speed causing no deformation or breakage of the gold wire (W2) at this time.
