  • Patent number: 7768104
    Abstract: An apparatus and method for a two semiconductor device package where the semiconductor devices are connected in electrical series. The first device is mounted P-side down on an electrically conductive substrate. Non-active area on the P side is isolated from the electrically conductive substrate. The second device is mounted P-side up at a spaced apart location on the substrate. Opposite sides of each are electrically connected to leads to complete the series connection of the two devices. A method of manufacturing such a package includes providing an electrically conductive lead frame, mounting one device P-side up and flipping the other device and mounting it P-side down on the lead frame with non-active area of the P side isolated from the lead frame, and connecting the other side of each device to separate leads. Isolation of the non-active area of the P side of the device can be through modification of the substrate or lead frame surface by grooves or raised portions.
