Title: Diffusion barrier for increased mirror reflectivity in reflective solderable contacts on high power led chip
Inventor: CARTER-COMAN CARRIE
IPC: H01L33/40
Filed: 2000-03-14
Granted: 2003-01-01
Abstract: A solderable light-emitting diode (LED) chip (26; 44) and a method of fabricating an LED lamp embodying the LED chip utilize a diffusion barrier (36; 46) that appreciably blocks molecular migration between two different layers of the LED chip during high temperature processes. In the preferred embodiment, the two different layers of the LED chip are a back reflector (34) and a solder layer (38). The prevention of intermixing of the materials in the back reflector and the solder layer impedes degradation of the back reflector with respect to its ability to reflect light emitted by the LED. The LED chip includes a high power AlInGaP LED (28) or other type of LED, a back reflector, a diffusion barrier and a solder layer. Preferably, the back reflector is composed of silver (Ag) or Ag alloy and the solder layer is made of indium (In), lead (Pb), gold (Au), tin (Sn), or their alloy and eutectics. In a first embodiment, the diffusion layer (36) is made of nickel (Ni) or nickel-vanadium (NiV). In a second embodiment of the invention, the diffusion barrier (46) is made of titanium-tungsten-nitride (TiW:N). In addition to preventing the intermixing of the In of the solder layer with the Ag of the back reflector, the diffusion layer prevents degradation of the Ag in the back reflector upon exposure to air. In an alternative embodiment, the diffusion layer is made of a non-conductive material.

Granted: 2003-07-21
Abstract: An example embodiment of a computer system utilizing a central snoop filter includes several nodes coupled together via a switching device. Each of the nodes may include several processors and caches as well as a block of system memory. All traffic from one node to another takes place through the switching device. The switching device includes a snoop filter that tracks cache line coherency information for all caches in the computer system. The snoop filter has enough entries to track the tags and state information for all entries in all caches in all of the system's nodes. In addition to the tag and state information, the snoop filter stores information indicating which of the nodes has a copy of each cache line. The snoop filter serves in part to keep snoop transactions from being performed at nodes that do not contain a copy of the subject cache line, thereby reducing system overhead, reducing traffic across the system interconnect busses, and reducing the amount of time required to perform snoop transactions.
