Ampere exhibited its Uni-Thermo series of products that use skeleton type Peltier elements at SEMICON Japan 2008.
The Peltier element is a semiconductor element that can control heat emission and absorption using electric current, and Peltier elements that fully utilize these characteristics are widely used in small scale temperature control. However, Ampere developed a skeleton type Peltier element and was thereby able to increase the size of the element compared to conventional elements and to eliminate the need for thick ceramic fixation. As a result, the new Peltier element can alleviate thermal distortion using its flexible structure and demonstrates a high level of reliability and a long lifespan with durability to withstand 100,000 cycles of repeated heating and cooling.


Peltier devices have no moving parts and do not generate noise. Ampere developed a set of temperature controllers that can cover a wide range of temperatures from -40˚C to 150˚C and that can support element sizes from 40mm to 70mm.

Next the company plans to expand its business centered on use of the Uni-Thermo series as a platform for semiconductor testing.
