Cast pedestal with heating element and coaxial heat exchanger
ActiveUS7327948B1High-temperature gradientHeat resistantSemiconductor/solid-state device manufacturingHigh-frequency/infra-red heating bakingHeat resistanceEngineering
The present invention provides a heat transfer assembly that, when coupled to an object, is capable of keeping the object at a uniform elevated temperature while removing large amounts of heat from an external source. The assembly may be contained in a pedestal for use in a UV-cure chamber. The heat transfer assembly includes a heating element to control the wafer temperature and a cooling element to remove incident IR heat from the wafer and pedestal. A heat resistant layer having a calibrated heat resistance is located between the heating and cooling elements and between the wafer and the cooling elements. The heat resistant layer is able to sustain high temperature gradient from the wafer to the coolant so that the coolant does not boil while permitting enough heat to be conducted away from the wafer to maintain the desired set-point temperature.

Broadband Power Amplifier with A High Power Feedback Structure
InactiveUS20090231042A1High power feedback structureLarge optimum load impedanceSemiconductor/solid-state device detailsSolid-state devicesBroadband power amplifierPower over
A broadband power amplifier using a novel high power feedback structure is disclosed in this patent. Feedback is widely used in amplifier design to broaden the bandwidth of the amplifier. Traditionally, the feedback resistor is either an axial resistor placed over the top of the transistor or a surface mount resistor with a long PCB trace making up the rest of the feedback path. However, each of these methods has it's limitations. The axial resistor doesn't have good heat sinking capability and therefore cannot handle high power. The feedback on PCB makes the feedback path long and becomes positive feedback at high frequency, thus limiting the high end frequency of operation of the amplifier in a stable region. The feedback structure disclosed in this patent has a good heat sinking path, has very short feedback path; allowing for higher frequency operation. We successfully applied the feedback structures to a Gallium Nitride (GaN) transistor, which is a new type of power transistor that has low parasitic capacitance and high optimum load impedance, and demonstrated an amplifier with very high output power over extraordinarily broad bandwidth. Matching networks have been optimized to improve performance and stability. We have demonstrated that unconditional stability is achievable while operating over a broad bandwidth using this feedback structure.

A head slider is related to an actuator block. A flexible printed circuit board is received on the surface of the actuator block. A head IC is mounted on the surface of the flexible printed circuit board. A heat conductive member is mounted on the head IC. The heat resistance of the heat conductive member is set smaller than that of the flexible printed circuit board. A larger amount of heat can be transmitted from the head IC to the actuator block. The actuator block is made of a metal material such as aluminum. The heat resistance of the actuator block is apparently smaller than that of the flexible printed circuit board. A larger amount of heat can be radiated from the actuator block as compared with the flexible printed circuit board. The head IC is thus reliably prevented from a rise in the temperature.
