Abstract
A process of making thermoelectric coolers by direct printing of n- and p-type semiconductor materials suitable for making thermoelectric coolers is disclosed. Micro Jet Printing of arrays on n and p-type materials belong to conductive site pads on non-conductive substrate and crystalization of these materials in the preferred direction as they cool produces thermoelectric cooler components without the need for sawing and machining operations. A non-conductive top substrate having conductive bonding pads is secured to the tops of the columns n and p-type semiconductor materials thereby forming an electrical and physical bond to make a thermoelectric cooler package.
