20090152717 | METHOD OF FORMING STACKED DIE PACKAGE - A method of packaging semiconductor integrated circuits, including the steps of providing a transfer film and forming a patterned, conductive layer on a surface of the transfer film. A first semiconductor integrated circuit (IC) then is attached to the transfer film, where an active side of the first IC is attached to the transfer film. A second semiconductor IC then is attached to the first IC, where a bottom side of the second IC is attached to a bottom side of the first IC. Die pads on an active surface of the second IC are electrically connected to the conductive layer with wires and then a resin material is provided on one side of the transfer film to encapsulate the first and second ICs, the wires and a portion of the conductive layer. Next the transfer film is removed, which exposes the active side of the first IC and the conductive layer. An electrical distribution layer is formed over the active side of the first IC and the conductive layer and conductive balls are attached to the electrical distribution layer. The conductive balls allow electrical interconnection to the first and second integrated circuits. | 06-18-2009 |

20120139067 | PRESSURE SENSOR AND METHOD OF PACKAGING SAME - A method of packaging a pressure sensor die that does not use pre-molded lead frames. Instead a lead frame array is attached to a tape and a non-conductive material is deposited on the lead frames. The non-conductive material is cured and the tape is removed. Pressure sensor dies then are attached to respective die pads of the lead frames and electrically connected to lead frame leads with bond wires. A gel is dispensed onto a top surface of the pressure sensor dies and then a lid is attached to each of the lead frames to cover the pressure sensor dies. The lead frames are singulated to form individual pressure sensor packages. | 06-07-2012 |

20140374855 | PRESSURE SENSOR AND METHOD OF PACKAGING SAME - A method of packaging a pressure sensor die begins with patterning and etching a metal strip and forming metal traces on the strip. Further build-up is performed to transform the metal strip into a layered substrate. Cavity walls are formed on one side of the strip with a molding process and then the metal on the back side of the strip is removed. Next semiconductor dies are attached to the strip within the cavities and electrically connected to pads formed on the surface of the strip and/or to pads on other ones of the dies. A gel coating is deposited over the dies and then a metal lid is secured over the cavity. The strip is then singulated along ones of the cavity walls to form multiple sensor devices. | 12-25-2014 |
