摘要: In a semiconductor device (100), a thinly-molded portion (8b) covering a whole of a heat dissipating surface (2b) portion of a lead frame (2) and a die pad space filled portion (8c, 8d) are integrally molded from a second mold resin (8), because of which adhesion between the thinly-molded portion (8b) and lead frame (2) improves owing to the die pad space filled portion (8c, 8d) adhering to a side surface of the lead frame (2). Also, as the thinly-molded portion (8b) is partially thicker owing to the die pad space filled portion (8c, 8d), strength of the thinly-molded portion (8b) increases, and a deficiency or cracking is unlikely to occur.

摘要: In a semiconductor device (100), a first skirt portion (7a) molded from a first mold resin (7) and a second skirt portion (8a) molded from a second mold resin (8) are provided on a heat dissipating surface (2b) of a lead frame (2) . Also, a thinly-molded portion (8b) is molded integrally with the second skirt portion (8a) from the second mold resin (8). According to this kind of configuration, adhesion between the thinly-molded portion (8b) and lead frame (2) is high, and the semiconductor device (100) with excellent heat dissipation and insulation is obtained.
