摘要:
A microelectronic package may be fabricated having a microelectronic die stack attached to a microelectronic substrate, wherein a first microelectronic die within the microelectronic die stack includes an opening or "window" formed therethrough. The first microelectronic die may be in electronic communication with a second microelectronic die within microelectronic die stack and/or in electrical communication with a microelectronic substrate upon which the microelectronic die stack may be attached, wherein the electronic communication may be created with a bond wire which extends through the opening or "window" in the first microelectronic die.

In described examples, an electronic system includes a first chip (101) of single-crystalline semiconductor, including a first electronic device embedded in a second chip (102) of single-crystalline semiconductor shaped as a container having a slab (104) bordered by ridges (103), and including a second electronic device. The nested chips are assembled in a container of low-grade silicon shaped as a slab (130) bordered by retaining walls (131) and including conductive traces and terminals. The first electronic device is connected to the second electronic device by attaching the first chip onto the slab of the second chip. The first and second electronic devices are connected to the container by embedding the second chip in the container. The nested first and second chips operate as an electronic system, and the container operates as the package of the system. For first and second devices as field effect transistors, the system is a power block.

LED devices includes a lead frame having a reflector cup with a round bottom surface and a wall surface having a variable inclination with respect to the bottom surface and defining an opening at an upper end thereof. An LED is mounted on the bottom surface of the reflector cup, and an LED module includes first and second LED device that emit different colors. The first and second LED devices have substantially matched far field patterns in a first and second direction, where a first viewing angle in the first direction is less than about 99°.

Ein Verfahren zur Fertigung von Leuchtmitteln schlägt ein Bereitstellen eines als Wärmesenke dienenden Trägers vor, der einen flächigen Chipmontagebereich umfasst. Der flächige Chipmontagebereich wird zur Erzeugung eines ersten Teilbereichs und wenigstens eines zweiten Teilbereichs strukturiert. Hierbei weist der erste Teilbereich nach dem Strukturieren eine lotabweisende Eigenschaft auf. Anschließend wird ein Lot auf den flächigen Chipmontagebereich aufgebracht, sodass dieses den wenigstens einen zweiten Teilbereich benetzt. Wenigstens ein optoelektronischer Körper wird in den wenigstens einen zweiten Teilbereich mit dem Lot am Träger befestigt. Schließlich werden zur Zuführung elektrischer Energie an den optoelektronischen Leuchtkörper Kontaktierungen ausgebildet.
摘要:
To provide a robust soldering process for a top finger of a surface mount device, a lead frame having a top finger and a semiconductor device having the same are disclosed, wherein the top finger comprises a groove and the groove is provided at the bottom surface of the top finger that establishes contact with a die and adjacent to the contact position between the top finger and die so as to prevent solder from overflowing onto a chip passivation ring, reducing the stress on the die and increasing the reliability.
