Solder bump placement for thermal management in flip chip amplifiers

Metal pillars are placed adjacent to NPN transistor arrays that are used in the power amplifier for RF power generation. By placing the metal pillars in intimate contact with the silicon substrate, the heat generated by the NPN transistor arrays flows down into the silicon substrate and out the metal pillar. The metal pillar also forms an electrical ground connection in close proximity to the NPN transistors to function as a grounding point for emitter ballast resistors, which form an optimum electrothermal configuration for a linear SiGe power amplifier.

DIRECT SUBSTRATE TO SOLDER BUMP CONNECTION FOR THERMAL MANAGEMENT IN FLIP CHIP AMPLIFIERS

Solder bumps are placed in direct contact with the silicon substrate of an amplifier integrated circuit having a flip chip configuration. A plurality of amplifier transistor arrays generate waste heat that promotes thermal run away of the amplifier if not directed out of the integrated circuit. The waste heat flows through the thermally conductive silicon substrate and out the solder bump to a heat-sinking plane of an interposer connected to the amplifier integrated circuit via the solder bumps.
