摘要

We present a CMOS-compatible method of fabricating buried channels within bulk single-crystal silicon serving as the substrate of CMOS circuitry. The channels were designed to provide a compact, forced convection heat transfer liquid cooling approach to microprocessor and integrated circuit thermal management The baseline fabrication process consumers 8-10% of front-side surface area and serves as a foundation for incorporation of buried-channel cooling with CMOS electronics. Channels were fabricated with diameters ranging from 43-92 μm with sacrificial surface area trenches 10 μm wide. A microchanne) heat transfer solution was designed, simulated, and tested with cooling of up to 21 W/cm~2. Compatibility with CMOS electronics was investigated by evaluating the post-process transistor performance of a simple oscillator circuit
