Thermal Copper Pillar Bump

Book excerpt: What Is Thermal Copper Pillar Bump The thermal copper pillar bump is a thermoelectric device that is made from thin-film thermoelectric material and is embedded in flip chip interconnects. It is used in the packaging of electronic and optoelectronic components, such as integrated circuits (chips), laser diodes, and semiconductor optical amplifiers. The thermal bump is also known as the thermal copper pillar bump (SOA). Thermal bumps, as opposed to traditional solder bumps, which provide an electrical path and a mechanical connection to the package, act as solid-state heat pumps and add thermal management functionality locally on the surface of a chip or to another electrical component. Conventional solder bumps also provide a mechanical connection to the package. A thermal bump has a diameter of 238 micrometers and a height of 60 micrometers.
