    摘要: A solderable light-emitting diode (LED) chip and a method of fabricating an LED lamp embodying the LED chip utilize a diffusion barrier 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 and a solder layer. 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 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 is made of nickel (Ni) or nickel-vanadium (NiV). In a second embodiment of the invention, the diffusion barrier 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 reflective properties in the back reflector upon exposure to air. In an alternative embodiment, the diffusion layer is made of a non-conductive material.

    摘要: A probe is locatable adjacent a selected region of a device under test (DUT), the selected region having a plurality of contacts. A generator is capable of establishing a plume of a ionized gas between the probe and the selected region of the DUT, the plume having sufficient cross-sectional area and electrical conductivity to complete an electrical connection between the probe and the plurality of contacts.

    摘要: There is disclosed a contactless test probe using an ionized gas discharge for making electrical contact with the device under test (DUT). In one embodiment the ionized gas discharge is at or below atmospheric pressure thereby reducing the complexity of the control environment. In one embodiment, the atmospheric gas discharge, i.e. the electrical probing medium, is created and controlled by a micro-hollow cathode. In a further embodiment an extension gate is used to extend/retard the range of the high-density discharge.
