Latest Patents

Hamilton's latest patents include a method of extracting heat from a semiconductor body, which focuses on cooling densely packaged semiconductor devices. This innovative approach utilizes microchannels that extract heat through forced convection, employing a fluid coolant positioned as close as possible to the heat source. The design maximizes heat sink surface area and improves heat transfer coefficients, allowing for higher power density in semiconductor devices without increasing junction temperature or compromising reliability. In a preferred embodiment, multiple microchannels are formed directly in the substrate of a silicon or silicon carbide chip mounted on a circuit board's ground plane. The microchannels consist of closed-ended slots or grooves with a generally rectangular cross-section, and fabrication methods include deposition, etching, lift-off processing, micromachining, and laser cutting techniques.

Another notable patent involves a closed-loop liquid cooling system for RF amplifier modules. This system features elongated microchannels connected between coolant manifolds, which conduct liquid coolant beneath one or more transistor dies to dissipate generated heat. The design includes a heat exchanger, a miniature circulating pump, and passive check valves with tapered passages to control coolant flow. These valves are integrated into the circulating pump, coolant manifolds, or microchannels, ensuring efficient operation without moving parts.
