摘要： A power device package for containing, protecting and providing electrical contacts for a power transistor includes a top and bottom lead frames for directly no-bump attaching to the power transistor. The power transistor is attached to the bottom lead frame as a flip-chip with a source contact and a gate contact directly no-bumping attaching to the bottom lead frame. The power transistor has a bottom drain contact attaching to the top lead frame. The top lead frame further includes an extension for providing a bottom drain electrode substantially on a same side with the bottom lead frame. In a preferred embodiment, the power device package further includes a joint layer between device metal of source, gate or drain and top or bottom lead frame, through applying ultrasonic energy.

摘要： A circuit package assembly is disclosed. The assembly includes a conductive substrate; a high-side n-channel metal oxide semiconductor field effect transistor (NMOSFET) having a source on a side facing a surface of the conductive substrate and in electrical contact therewith and a low-side standard n-channel metal oxide semiconductor field effect transistor (NMOSFET) having a drain on a side facing the conductive substrate and in electrical contact therewith. Co-packaging of high-side and low-side NMOSFETs in this manner may reduce package size and parasitic inductance and capacitance compared to conventional packaging.

摘要： A dual flat non-leaded semiconductor package is disclosed. A method of making a dual flat non-leaded semiconductor package includes forming a leadframe having a die bonding area with an integral drain lead, a gate lead bonding area and a source lead bonding area, the gate lead bonding area and a source lead bonding area being of increased area; bonding a die to the die bonding area; coupling a die source bonding area to the source lead bonding area; coupling a die gate bonding area to the gate lead bonding area; and partially encapsulating the die, the drain lead, the gate lead and the source lead to form the dual flat non-leaded semiconductor package.
