Abstract: A bonding pad for an integrated circuit is formed by a stack of bonding pad layers. A lower bonding pad layer is supported by a bonding pad support layer. A passivation layer extends over the lower bonding pad layer and includes a passivation opening at a portion of an upper surface of the lower bonding pad layer. An upper bonding pad layer rests on said passivation layer and in the passivation opening in contact with the lower bonding pad layer.

Abstract: The present disclosure is directed to embodiments of sensor package including a doped resin on respective surfaces and sidewalls of a transparent portion, a sensor die, and a support structure extending from the transparent portion to the sensor die. The support structure suspends the transparent portion over a sensor of the sensor die. The doped resin is doped with an additive material, and the additive material is activated by exposing the doped resin to a laser. The doped resin is exposed to the laser forming conductive layers extending along the doped resin for providing electrical connections within the sensor package and to electronic components external to the embodiments of the sensor die packages. The conductive layers are at least partially covered by a non-conductive layer.

Abstract: A trench in a semiconductor substrate is lined with a first insulation layer. A hard mask layer deposited on the first insulation layer is used to control performance of an etch that selectively removes a first portion of the first insulating layer from an upper trench portion while leaving a second portion of first insulating layer in a lower trench portion. After removing the hard mask layer, an upper portion of the trench is lined with a second insulation layer. An opening in the trench that includes a lower open portion delimited by the second portion of first insulating layer in the lower trench portion and an upper open portion delimited by the second insulation layer at the upper trench portion, is then filled by a single deposition of polysilicon material forming a unitary gate/field plate conductor of a field effect rectifier diode.

Abstract: The present disclosure is directed to embodiments of optical sensor packages. For example, at least one embodiment of an optical sensor package includes a light-emitting die, a light-receiving die, and an interconnect substrate within a first resin. A first transparent portion is positioned on the light-emitting die and the interconnect substrate, and a second transparent portion is positioned on the light-receiving die and the interconnect substrate. A second resin is on the first resin, the interconnect substrate, and the first and second transparent portions, respectively. The second resin partially covers respective surfaces of the first and second transparent portions, respectively, such that the respective surfaces are exposed from the second resin.

Abstract: A substrate includes electrically-conductive tracks. A semiconductor chip is arranged on the substrate and electrically coupled to selected ones of the electrically-conductive tracks. Containment structures are provided at selected locations on the electrically-conductive tracks, where the containment structures have respective perimeter walls defining respective cavities. Each cavity is configured to accommodate a base portion of a pin holder. These pin holders are soldered to the electrically-conductive tracks within the cavities defined by the containment structures. Each containment structure may be formed by a ring of resist material configured to receive solder and maintain the pin holders in a desired alignment position.

Abstract: A method of forming a wafer-level package includes singulating a wafer into a plurality of reconstituted integrated circuit dice, affixing a carrier to a front side of the plurality of integrated circuit dice, and forming a laser direct structuring (LDS) activatable resin over a back side of the plurality of integrated circuit dice, over side edges of the plurality of integrated circuit die, and over adjacent portions of the carrier. Desired areas of the LDS activatable resin are activated to form conductive areas within the LDS activatable resin, at least one of the conductive areas associated with each integrated circuit die being formed to contact a respective a respective pad of that integrated circuit die and to run alongside to and in contact with a side of the LDS activatable resin in contact with a side edge of that integrated circuit die.

Abstract: A semiconductor package that is a proximity sensor includes a light transmitting die, a light receiving die, an ambient light sensor, a cap, and a substrate. The light receiving die and the light transmitting die are coupled to the substrate. The cap is coupled to the substrate forming a first chamber around the light transmitting die and a second chamber around the light receiving die. The cap further includes a recess with contact pads. The ambient light sensor is mounted within the recess of the cap and coupled to the contact pads. The cap includes electrical traces that are coupled to the contact pads within the recess coupling the ambient light sensor to the substrate. By utilizing a cap with a recess containing contact pads, a proximity sensor can be formed in a single semiconductor package all while maintaining a compact size and reducing the manufacturing costs of proximity sensors.

Abstract: A method of forming a solder connection includes forming a solder mask on a thermal pad of a printed circuit board. The solder mask leaves unmasked portions of the thermal pad and forming the solder mask includes forming a plurality of mask stripes extending from edges of each unmasked portion towards a center of the unmasked portion. The method includes depositing solder paste on the unmasked portions of the thermal pad and placing an exposed thermal pad of an integrated circuit package on the solder paste deposited on the thermal pad of the printed circuit board. The method includes forming a solder connection by heating the solder paste between the unmasked portions of the thermal pad on the printed circuit board and the exposed thermal pad of the integrated circuit package.
