英文摘要: Abstract(#br)This study describes the development of packaging for high-power AlGaN/GaN high electron mobility transistors (HEMTs) on a silicon substrate. A transistor is attached to a V-grooved copper base, and mounted on a TO-3P lead-frame. Unlike flipchip or copper-molybdenum-copper (CMC)-based packaging technology, which is popular in the GaN HEMT industry, the proposed packaging structure is implemented on the periphery of the surface of the device to promote thermal dissipation from the Si substrate. The various thermal paths from the GaN gate junction to the case dissipate heat by spreading it to a protective coating; transferring it through bond wires; spreading it laterally throughout the device structure through an adhesive layer, and spreading it vertically through the bottom...
