Abstract:
Embodiments are directed to a package that includes an electric device having a recess. In one embodiment, the electric device is a sensor and the recess reduces signal drift of the sensor caused by thermal expansion of the package. In another embodiment, the recess is substantially filled with adhesive material, thus increasing adhesion between the electric device and a substrate of the package while at the same time allowing for lower adhesive fillets.
Abstract:
A wafer level chip scale package (WLCSP) includes a semiconductor substrate, a back end of line (BEOL) layer on the semiconductor substrate and having a peripheral edge recessed inwardly from an adjacent peripheral edge of the semiconductor substrate. A first dielectric layer is over the BEOL layer and wraps around the peripheral edge of the BEOL layer. A redistribution layer is over the first dielectric layer and a second dielectric layer is over the redistribution layer.
Abstract:
A method of making an electronic device may include positioning an integrated circuit (IC) die on an upper surface of a grid array substrate having connections on a lower surface thereof and coupling respective bond pads of the IC die to the grid array with bond wires. The method may also include forming a first encapsulating layer over the IC die and bond wires and positioning a heat spreader on the substrate above the first encapsulating layer after forming the first encapsulating layer. The method may further include forming a second encapsulating layer over the first encapsulating layer and embedding the heat spreader in the second encapsulating layer.
Abstract:
An electronic device includes an integrated circuit chip mounted to a heat slug. The heat slug has a peripheral region having first thickness along a first direction, the peripheral region surrounding a recess region (having a second, smaller, thickness along the first direction) that defines a chip mounting surface along a second direction perpendicular to the first direction. The recess region defines side borders and a nook extends into the heat slug along the side borders. An insulating body embeds the integrated circuit one chip and heat slug. Material of the insulating body fills the nook.

Methods and devices for packaging integrated circuits. A packaged device may include an integrated circuit, a first packaging component including a patterned surface, and a second packaging component. The patterned surface of the first packaging component may be adhesively coupled to a surface of the second packaging component or a surface of the integrated circuit. The integrated circuit may be at least partially enclosed between the first and second packaging components. A packaging method may include patterning a surface of a packaging component of an integrated circuit package. The surface of the packaging component may be for adhesively coupling to a second component to at least partially enclose an integrated circuit in the integrated circuit package.

Abstract:
A surface mount package of a semiconductor device, has: an encapsulation, housing at least one die including semiconductor material; and electrical contact leads, protruding from the encapsulation to be electrically coupled to contact pads of a circuit board; the encapsulation has a main face designed to face a top surface of the circuit board, which is provided with coupling features designed for mechanical coupling to the circuit board to increase a resonant frequency of the mounted package. The coupling features envisage at least a first coupling recess defined within the encapsulation starting from the main face, designed to be engaged by a corresponding coupling element fixed to the circuit board, thereby restricting movements of the mounted package.
Abstract:
Embodiments of the present disclosure are related to manufacturing system-in-packages at wafer-level. In particular, various embodiments are directed to adhering a first wafer to a second wafer and adhering solder balls to contact pads of the first wafer. In one embodiment, a first wafer having first and second surfaces is provided. The first wafer includes bond pads located on the first surface that are coupled to a respective semiconductor device located in the first wafer. A second wafer having an electrical component located therein is provided. A conductive adhesive is provided on at least one of the first wafer and the second wafer. Conductive balls are provided on the bond pads on the first surface of the first wafer. The conductive balls and the conductive adhesive are heated to cause the conductive balls to adhere to the bond pad and the conductive adhesive to adhere the first wafer to the second wafer.
Abstract:
An integrated circuit (IC) device includes an IC and encapsulating material surrounding the IC. Leads are coupled to the IC and extend outwardly from sides of the encapsulating material, with each lead having three contiguous exposed segments with upper and lower bends defining a Z-shape. In another example, the leads include an upper horizontal segment, lower horizontal segment, and intermediate curved segment extending upwardly from the upper horizontal segment and downwardly to the lower horizontal segment.
