eTEC thin film embedded thermoelectric cooler functions as miniature, solid-state heat pump; is ideal for cooling hot spots that result from localized areas of high heat flux on an IC. Operates by Peltier effect. Is designed with compound semiconductor materials that have high electrical conductivity and poor thermal conductivity. Adds 100 µm of height to a heat spreader. Has ms response time. Said to pump a max. heat flux of 150 W/cm2 with some designs delivering as much as 400 W/cm2. Can operate in a high COP regime and pump a heat flux of 50 – 100 W/cm2.
