摘要: A semiconductor sensor device is assembled using a pre-molded lead frame having first and second die flags. The first die flag includes a cavity. A pressure sensor die (P-cell) is mounted within the cavity and a master control unit die (MCU) is mounted to the second flag. The P-cell and MCU are electrically connected to leads of the lead frame with bond wires. The die attach and wire bonding steps are each done in a single pass. A mold pin is placed over the P-cell and then the MCU is encapsulated with a mold compound. The mold pin is removed leaving a recess that is next filled with a gel material. Finally a lid is placed over the P-cell and gel material. The lid includes a hole that that exposes the gel-covered active region of the pressure sensor die to ambient atmospheric pressure outside the sensor device.

摘要: A method of attaching a solder ball to a bonding pad includes disposing flux on the bonding pad, attaching a conductive metal ring to the pad using the flux, and placing the solder ball in the ring. A reflow operation is performed that secures the ring to the pad and melts the solder ball into and around the ring. A solder joint is formed between solder ball and the pad, with the ring secured within the ball. Use of the ring allows for higher stand-off height to be achieved with similar solder ball size, without having to use bigger ball size as in the conventional method, which causes solder ball bridging. With higher stand-off height, better board level reliability performance can be obtained.

摘要: A semiconductor die has a polyimide layer disposed on its top surface. At the corners of the die top, the polyimide layer is roughened or patterned, but not enough such that the die top is exposed. The patterned corners enhance adhesion of a mold compound later disposed on the die top by allowing for enhanced hydrogen bonding between the polyimide layer and the mold compound.

摘要: A packaged semiconductor device has an integrated circuit (IC) die and a heat spreader. The heat spreader has a first portion with holes formed entirely therethrough. The first portion is attached to the die using thermally-conductive adhesive that fills the holes. The holes enable the heat spreader to be attached to the die without placing excess pressure on the IC die that could cause the die to crack.

摘要: A method of assembling a pressure sensor device includes providing a substrate having a plurality of substrate connection pads. A pressure sensor die is attached to a first major surface of the substrate and bond pads of the pressure sensor die are electrically connected to the respective substrate connection pads. A retractable cavity pin is placed on the first major surface of the substrate such that the cavity pin covers the pressure sensor die and the electrical connections to the die. A molding compound is then dispensed onto the first major surface of the substrate such that the molding compound surrounds the pressure sensor die and the cavity pin. The cavity pin is retracted such that a cavity is formed around the pressure sensor die and a gel material is dispensed within the cavity such that the gel material fills the cavity and covers the pressure sensor die.

摘要: A semiconductor device has a die mounted on a die paddle that is elevated above and thermally connected via tie bars to a heat sink structure. Heat generated by the die flows from the die to the die paddle to the tie bars to the heat sink structure and then to either the external environment or to an external heat sink. By elevating the die/paddle sub-assembly above the heat sink structure, the packaged device is less susceptible to delamination between the die and die attach adhesive and/or the die attach adhesive and the die paddle. An optional heat sink ring can surround the die paddle.
