Microscale heat transfer
Advances in microfabrication processes have led to a continuous miniaturization of Field Effect Transistors (FET) that contain semiconductor (e.g., silicon), insulator (e.g., silicon dioxide), and metallic (e.g., copper interconnects) layers only a few nanometers thick. Ever increasing demand for faster microprocessors and the continuous trend to pack more transistors on a … [Read more...]
Thermal Issues in GaAs Analog RF Devices
Wireless communication and advanced radar systems require circuitry that can operate at frequencies greater than 2 GHz and at high power levels. Analog gallium arsenide (GaAs) semiconductors are frequently used in these applications and present additional challenges for thermal engineers compared to silicon semiconductors. Whereas thermal characterization modeling and … [Read more...]
