    摘要: A method and apparatus to minimize thermal impedance using copper on the die or chip backside. Some embodiments use deposited copper having a thickness chosen to complement a given chip thickness, in order to reduce or minimize wafer warpage. In some embodiments, the wafer, having a plurality of chips (e.g., silicon), is thinned (e.g., by chemical-mechanical polishing) before deposition of the copper layer, to reduce the thermal resistance of the chip. Some embodiments further deposit copper in a pattern of bumps, raised areas, or pads, e.g., in a checkerboard pattern, to thicken and add copper while reducing or minimizing wafer warpage and chip stress.

    摘要: A method and arrangement for dissipating heat from a localized area within a semiconductor die is presented. A semiconductor die is constructed and arranged to have at least one conduit portion therein. At least a portion of the conduit portion is proximate to the localized area. The conduit portion is at least partially filled with a heat-dissipating material. The conduit portion absorbs heat from the localized area and dissipates at least a portion of the heat away from the localized area. As such, thermal stress on the die is reduced, and total heat from the die is more readily dissipated.

    摘要: A computer system and its method of cooling are provided. A vapor chamber serves as a heat spreader for heat from the microelectronic die. A thermoelectric module serves to cool the vapor chamber and maintain proper functioning of the vapor chamber, thus keeping the microelectronic die cooled. A controller receives input from five temperature sensors, and utilizes the input to control current to the thermoelectric module and voltage/current to a motor that drives a fan and provides additional cooling. A current sensor allows the controller to monitor and limit power provided to the thermoelectric module.
