Latest Patents

One of his latest patents is a cooling system for pulsed power electronics. This invention discloses an apparatus designed to reduce peak temperatures and thermal excursions of semiconductor devices, especially in pulsed power applications. The apparatus utilizes Phase Change Material (PCM) to thermally couple with the semiconductor device, absorbing heat and maintaining a constant temperature during its phase change from solid to liquid. This innovative approach allows the PCM to melt when the device approaches maximum temperature, effectively drawing heat away and lowering peak temperatures. Additionally, the PCM solidifies after the pulse period, releasing the absorbed heat and preventing excessive cooling.

Another significant patent by Hashemi is a method and structure for temperature stabilization in semiconductor devices. This invention involves depositing a carbon-based polymer on top of interconnect metal lines within the semiconductor die. The polymer acts as a cushion, dampening temperature excursions during power pulses. It absorbs energy without a rise in temperature, ensuring that the semiconductor devices do not experience abrupt temperature increases. Conversely, when no power pulse is being dissipated, the polymer releases stored energy while maintaining a constant temperature, further stabilizing the semiconductor's thermal environment.
