    摘要： The present invention provides an ohmic contact for a copper metallization whose heat diffusion is improved and cost is reduced. Therein, the ohmic contact is formed through a depositing and an annealing of three metal layers of Pd, Ge and Cu; and, the contact resistance of the ohmic contact is adjusted by the thicknesses of the three layers.

    摘要： A bi-level structure based on copper metallization technique has been applied to backside of gallium arsenide (GaAs) devices. The foundation where the structure stands on is device substrate backside, on which a layer of diffusion barrier is deposited first, and to the top of it, a layer of copper metallization is plated to enhance device performance. The barrier layer can be selected from tungsten (W), tungsten nitride (WN), or titanium tungsten nitride (TiWN) by sputtering or evaporating, which effectively prevents copper from diffusing into GaAs substrate. The layer of copper metallization, formed by employing anyone of sputtering, evaporating, or electroplating, proves to offer attractive thermal and electrical conductivity and mechanical strength and the like. Moreover, these characteristic improvements coupled with a fascinating part, low cost, would benefit and motivate global GaAs fabs.

    摘要翻译： 基于铜金属化技术的双层结构已被应用于砷化镓（GaAs）器件的背面。 结构所在的基础是器件衬底背面，其上首先沉积一层扩散阻挡层，并且在其顶部镀有一层铜金属化以增强器件性能。 阻挡层可以通过溅射或蒸发从钨（W），氮化钨（WN）或氮化钨（TiWN）中选择，这有效地防止铜扩散到GaAs衬底中。 通过使用任何溅射，蒸发或电镀形成的铜金属化层证明提供有吸引力的热导和导电性和机械强度等。 此外，这些特征改进加上迷人的部分，低成本，将有利于并激励全球砷化镓晶圆厂。

    摘要： An adjustable collimator and a sputtering apparatus with the same are provided. The adjustable collimator comprises an adjustable main body, first and second collimating elements. The adjustable main body has an interior space, a top portion, a bottom portion and an adjuster between the top portion and the bottom portion. The adjuster is adapted for adjusting a relative distance between the top portion and the bottom portion. A first collimating element fixed inside the interior space of the top portion in a manner to move with the top portion and a second collimating element fixed inside the interior space of the bottom portion to move with the bottom portion. When the adjustable collimator applies to sputtering apparatus, it can easily control the incident angel of the molecule of the sputtering material by adjusting a relative distance between the top and bottom portion.

    摘要： A package structure for solid-state lighting with low thermal resistance is revealed. A solid-state light is set on a circuit board with high thermal conductivity. A connection layer is used for binding the circuit board with high thermal conductivity and the heat sink substrate. A first attachment layer is set between the heat sink substrate and the connection layer; and a second attachment is set between the connection layer and the circuit board with high thermal conductivity. The connection layer is made of metals or metallic composite materials with high heat dissipation and low thermal expansion coefficients. Thereby, the thermal resistance is lower than the structures according to the prior art. In addition, the thermal stress produced between the heat sink substrate and the circuit board with high thermal conductivity can be buffered by the connection layer for increasing lifetime of the package structure according to the present invention.
