  • Method for fabricating a plurality of elastic probes in a row
    Patent number: 7477065
    Abstract: A method of forming a plurality of elastic probes in a row is disclosed. Firstly, a substrate is provided, then, a shaping layer is formed on the substrate so as to offer two flat surfaces in parallel. A photoresist layer is formed on the substrate and on the shaping layer. Then, the photoresist layer is patterned to form a plurality of slots crossing an interface between the two flat surfaces where a plurality of elastic probes are formed in the slots. In one embodiment, the interface is an edge slope of the shaping layer so that each of the elastic probes has at least an elastic bending portion. During chip probing, the shifting direction of the elastic probes due to overdrives is perpendicular to the arranging direction of the bonding pads so that the elastic probes are suitable for probing chips with high-density and fine-pitch bonding pads.

  • Thermal regenerative granular-moving bed apparatus
    Patent number: 7476364
    Abstract: A thermal regenerative granular-moving bed apparatus for a gas de-pollutant process includes a plurality of recycling granular material, a heat-and-clean unit, a heat-recycling unit, and a granular material-cleaning unit. The heat-and-clean unit heats the granular material to further heat a polluted gas, de-pollutes the gas, and detains pollutants or particles from the de-polluting. The heat-recycling unit constructed on top of the heat-and-clean unit has the hot up-flowing de-polluted gas heat-exchange with the down-flowing cold granular material. The granular material-cleaning unit transports the granular material from a lower-end of the heat-and-clean unit to an upper end of the heat-recycling unit and re-activates the granular material during the transportation.
