摘要： A semiconductor package has a controlling IC attached to a die pad using an epoxy molding compound (EMC) pad. The EMC pad is formed so as to be slightly larger than the controlling IC. EMC pads are cut from an EMC pad pattern which is formed from a predetermined number of EMC tablets. The EMC pad pattern is molded by heating and pressing the EMC tablets into a wafer shape having a thickness of approximately 0.3 mm and a diameter of approximately 100 mm. Such a thin EMC pad is capable of providing sufficient dielectric strength, and allows for manufacturing of semiconductor packages at lower cost. In addition, conventional equipment can be used to fabricate the semiconductor packages. The packages are flexible, and even a thin package is not easily broken.

摘要： A semiconductor package has a structure in which a leadframe pad to which a semiconductor die is attached and inner leads electrically connected to the leadframe pad are covered by a molded housing, and outer leads extending from the inner leads protrude from a side surface of the molded housing to the outside. The outer leads include a first outer lead disposed in a central portion of the molded housing, second and third outer leads respectively disposed in a right and left of the first outer lead. The second and third outer leads each have bent portions in portions where they are adjacent to the side surface of the molded housing, the bent portions protruding to increase a space between the first outer lead and the bent portions in the molded housing. At least one of the bent portions of the second and third outer leads is covered by an extended portion of the molded housing.

摘要： A power device having a multi-chip package structure and a manufacturing method therefor are provided. In the power device, a transistor, which is a switching device, and a control integrated circuit (IC) chip, which is a driving device, are mounted together in a package, thereby requiring a high insulation withstand voltage between the transistor chip and the control IC chip. The power device and the manufacturing method can simplify a packaging process by attaching the control IC chip on a chip pad of a lead frame using an insulating adhesive tape at a level with the transistor chip. Furthermore, the overall size of a package in the power device can be reduced by attaching the control IC chip on top of the transistor chip using the insulating adhesive tape. In the case of attaching the control IC chip on the top of the transistor chip, a liquid non-conductive adhesive can be used instead of an insulating adhesive tape.
