  • Patent number: 10787361
    Abstract: A semiconductor sensor device includes a lead frame flag having a vent hole, an interposer mounted on the flag and having a vent hole in fluid communication with the vent hole of the flag, and a sensor die having an active region. The sensor die is mounted on and electrically connected to the interposer in a flip-chip manner such that the vent hole of the interposer is in fluid communication with the active region of the sensor die. Bond wires electrically connect the interposer to one or more other components of the device. A molding compound covers the sensor die, the interposer, and the bond wires. The sensor die may be a pressure-sensing (P-cell) die, and the device may also include a micro-controller unit (MCU) die and an acceleration-sensing (G-cell) die, for tire pressure monitoring applications.

  • Patent number: 9293395
    Abstract: A lead frame for a semiconductor device includes a die paddle and leads situated on a perimeter of the lead frame. The die paddle has a metal frame and a number of substantially linear metal connecting bars within the frame. The connecting bars interconnect different locations of the frame to form a multiple triangles, where a triangular-shaped cavity is formed within each triangle. An overall area of the cavities is greater than an overall area of the connecting bars.

  • Patent number: 9171786
    Abstract: An integrated circuit (IC) die has an active side and an inactive side, opposite the active side. A recess is formed within the interior of the inactive side and extends partially through the integrated circuit towards the active side. The IC die is part of a packaged IC device, where the die is attached to a package component such as a lead frame, substrate, or another die, using die attach adhesive that fills the recess, thereby providing a more reliable bond between the IC die and the package component.

  • Patent number: 9136399
    Abstract: A semiconductor device package is assembled using a jig that alters the shape of gel material disposed in a cavity in the package. In one embodiment, a jig having a concave bottom surface is inserted onto uncured gel material disposed within a cavity in a housing of the package to change a top surface of the gel from having a concave shape to a convex shape. The gel is then cured with the jig in place. When the jig is subsequently removed, the cured gel retains the convex shape, which helps to avoid any bond wires from being exposed. The re-shaped gel material reduces internal stresses during thermal cycling and can therefore reduce permanent damage to the package otherwise resulting from such thermal cycling.

  • Publication number: 20150069537
    Abstract: A semiconductor sensor device has a MCU die and an acceleration-sensing die mounted on a die paddle of a lead frame. The MCU die is connected to leads of the lead frame with first bond wires and the acceleration-sensing die is connected to the MCU die with second bond wires. An interposer is flip-chip mounted on a top surface of the MCU die. The MCU die, acceleration-sensing die and a portion of the interposer are covered with a molding compound. A pre-packaged pressure sensor is flip-chip mounted on a top, exposed surface of the interposer. The interposer provides electrical connection between the pre-packaged pressure sensor and the MCU die.
