  • Publication number: 20230197826
    Abstract: Self-aligned gate endcap (SAGE) architectures with improved caps, and methods of fabricating self-aligned gate endcap (SAGE) architectures with improved caps, are described. In an example, an integrated circuit structure includes a first gate structure over a first semiconductor fin. A second gate structure is over a second semiconductor fin. A gate endcap isolation structure is between the first gate structure and the second gate structure. The gate endcap isolation structure has a higher-k dielectric cap layer on a lower-k dielectric wall. The higher-k dielectric cap layer includes hafnium and oxygen and has 70% or greater monoclinic crystallinity.

  • Patent number: 8691404
    Abstract: A method of constructing a solid-state energy-density micro radioisotope power source device. In such embodiments, the method comprises depositing the pre-voltaic semiconductor composition, comprising a semiconductor material and a radioisotope material, into a micro chamber formed within a power source device body. The method additionally includes heating the body to a temperature at which the pre-voltaic semiconductor composition will liquefy within the micro chamber to provide a liquid state composite mixture. Furthermore, the method includes cooling the body and liquid state composite mixture such that liquid state composite mixture solidifies to provide a solid-state composite voltaic semiconductor, thereby providing a solid-state high energy-density micro radioisotope power source device.
