The application of thermoelectric technology to cool microelectronic circuits is not new. It has been established for some time that the technology can be used in cooling, heating and micro-power generation applications, and can offer some distinct advantages over other technologies. For example, in cooling or refrigeration, the technology does not require any chlorofluorocarbons or other fluid that may need to be replaced; can achieve temperature control to within ±0.1 °C; is electrically quiet in operation; the modules are relatively small in size and weight; and do not import dust or other particles which may cause an electrical short circuit [2].
