  • Publication number: 20110042803
    Abstract: A method for fabricating a through interconnect on a semiconductor substrate includes the steps of forming a via on a first side of the substrate part way through the substrate, forming an electrically insulating layer on the first side and in the via, forming an electrically conductive layer at least partially lining the via, forming a first contact on the conductive layer in the via, and thinning the substrate from a second side at least to the insulating layer in the via. The method can also include the step of forming a second contact on a second side of the substrate in electrical contact with the first contact. The method can be performed on a semiconductor wafer to form a wafer scale interconnect component. In addition, the interconnect component can be used to construct semiconductor systems such as a light emitting diode (LED) systems.

  • Patent number: 7892891
    Abstract: Techniques for dicing wafer assemblies containing multiple metal device dies, such as vertical light-emitting diode (VLED), power device, laser diode, and vertical cavity surface emitting laser device dies, are provided. Devices produced accordingly may benefit from greater yields and enhanced performance over conventional metal devices, such as higher brightness of the light-emitting diode and increased thermal conductivity. Moreover, such techniques are applicable to GaN-based electronic devices in cases where there is a high heat dissipation rate of the metal devices that have an original non- (or low) thermally conductive and/or non- (or low) electrically conductive carrier substrate that has been removed.

  • Patent number: 7829440
    Abstract: A method for the separation of multiple dies during semiconductor fabrication is described. On an upper surface of a semiconductor wafer containing multiple dies, a seed metal layer may be used to grow hard metal layers above it for handling. Metal may be plated above these metal layers everywhere except where a block of stop electroplating (EP) material exists. The stop EP material may be obliterated, and a barrier layer may be formed above the entire remaining structure. The substrate may be removed, and the individual dies may have any desired bonding pads and/or patterned circuitry added to the semiconductor surface. The remerged hard metal after laser cutting and heating should be strong enough for handling. Tape may be added to the wafer, and a breaker may be used to break the dies apart. The resulting structure may be flipped over, and the tape may be expanded to separate the individual dies.

  • Publication number: 20100021560
    Abstract: A silver-supporting bamboo charcoal (BC/Ag) comprising silver in different weight ratio of 26% (BC/Ag-1), 29% (BC/Ag-2), 34% (BC/Ag-3), 48% (BC/Ag-4), 57% (BC/Ag-5), or 75% (BC/Ag-6). The BC powders (particle size<10 ?m, Taiwan Paiho) are activated with surfactant sodium alginate under stirred for 1 h. The as-prepared BC powders (2 g) are immersed into 100 mL of biamminesilver nitrate ([Ag(NH3)2]NO3) solutions, which are formed by adding 28 wt. % aqueous ammonia into AgNO3 solution at room temperature. After stirring for 1 h, dilute aqueous solutions of hydrazine monohydrate are separately prepared and introduced to the BC-AgNO3 solutions in appropriate quantities (molar ratio 1:1 with respect to silver nitrate) by a syringe. Stirring is continued under inert atmosphere at room temperature for another 4 h. The BC/Ag particles are separated and washed with deionized water and ethanol, then dried in vacuum at 60° C. for overnight.
