    Abstract: The present invention is directed toward an apparatus and method of reinforcement of lead bonding in microelectronics packages. In one embodiment, a microelectronics package includes a microelectronics device having a bond pad, a conductive lead having a first end bonded to the bond pad to form a lead bond, an encapsulating material at least partially disposed about the conductive lead, and a reinforcement portion at least partially disposed about the lead bond and at least partially coupling the first end to the bond pad. The reinforcement portion has a greater modulus of elasticity and/or a greater bond strength than the encapsulating material. During thermal cycling of the microelectronics package, bond liftoff due to CTE mismatch is prevented by the reinforcement portion. The reinforcement portion may include a non-conductive adhesive material that physically secures the conductive lead to the bond pad, or alternately, an electrically conductive adhesive material that both physically and/or electrically couples the conductive lead to the bond pad. In an alternate embodiment, a microelectronics package includes a microelectronics device, an interposer, a plurality of conductive leads and a plurality of bond pads, and the reinforcement portion is disposed about a plurality of lead bonds. In this embodiment, the reinforcement portion may include a non-conductive adhesive material, or an anisotropically conductive material.

    Abstract: Solid state lighting devices having side reflectivity and associated methods of manufacturing are disclosed herein. In one embodiment, a method of forming a solid state lighting device includes attaching a solid state emitter to a support substrate, mounting the solid state emitter and support substrate to a temporary carrier, and cutting kerfs through the solid state emitter and the substrate to separate individual dies. The solid state emitter can have a first semiconductor material, a second semiconductor material, and an active region between the first and second semiconductor materials. The individual dies can have sidewalls that expose the first semiconductor material, active region and second semiconductor material. The method can further include applying a reflective material into the kerfs and along the sidewalls of the individual dies.

    Abstract: An improved image sensor wherein a first micro-lens array comprised of one or more micro-lenses is positioned over a cavity such that incoming light is focused on the photo sensors of the image sensor. The first micro-lens array may collimate and focus incoming light onto the photo sensors of the image sensor, or may collimate incoming light and direct it to a second micro-lens array which then focuses the light onto the photo sensors. A method of fabricating the improved image sensor is also provided wherein the cavity and first micro-lens array are formed by use of a sacrificial material.
