  • Publication number: 20240120338
    Abstract: A semiconductor device structure is provided. The semiconductor device has a first dielectric wall between an n-type source/drain region and a p-type source/drain region to physically and electrically isolate the n-type source/drain region and the p-type source/drain region from each other. A second dielectric wall is formed between a first channel region connected to the n-type source/drain region and a second channel region connected to the p-type source/drain region. A contact is formed to physically and electrically connect the n-type source/drain region with the p-type source/drain region, wherein the contact extends over the first dielectric wall. The first electric wall has a gradually decreasing width W5 towards a tip of the dielectric wall from a top contact position between the first dielectric wall and either the n-type source/drain region or the p-type source/drain region.

  • Publication number: 20230292616
    Abstract: The present invention introduces a new hybrid thermal energy harvesting device that combines electrochemistry and semiconductors to achieve simultaneous high saturation thermo-voltage and high current density. This innovation demonstrates the synergistic effect of integrating semiconductors, commonly used in solid-state thermoelectrics for high current density, with ion-conducting polymer electrolytes, known for their high thermo-voltage. The device ensures constant high-power output from continuous or periodic heat sources. It directly converts heat into electricity for immediate use or stores electricity derived from low-grade temperature differentials and temperature ranges for later discharge. It exhibits characteristics resembling both photovoltaics and capacitors simultaneously.
