  • Publication number: 20230091603
    Abstract: Techniques are provided for forming one or more thermoelectric devices integrated within a substrate of an integrated circuit. Backside substrate processing may be used to form adjacent portions of the substrate that are doped with alternating dopant types (e.g., n-type dopants alternating with p-type dopants). The substrate can then be etched to form pillars of the various n-type and p-type portions. Adjacent pillars of opposite dopant type can be electrically connected together via a conductive layer. Additionally, the top portions of adjacent pillars are connected together, and the bottom portions of a next pair of adjacent pillars being coupled together, in a repeating pattern to ensure that current flows through the length of each of the doped pillars. The flow of current through alternating n-type and p-type doped material creates a heat flux that transfers heat from one end of the integrated thermoelectric device to the other end.

  • Patent number: 11587827
    Abstract: Conformal hermetic dielectric films suitable as dielectric diffusion barriers over 3D topography. In embodiments, the dielectric diffusion barrier includes a dielectric layer, such as a metal oxide, which can be deposited by atomic layer deposition (ALD) techniques with a conformality and density greater than can be achieved in a conventional silicon dioxide-based film deposited by a PECVD process for a thinner contiguous hermetic diffusion barrier. In further embodiments, the diffusion barrier is a multi-layered film including a high-k dielectric layer and a low-k or intermediate-k dielectric layer (e.g., a bi-layer) to reduce the dielectric constant of the diffusion barrier. In other embodiments a silicate of a high-k dielectric layer (e.g., a metal silicate) is formed to lower the k-value of the diffusion barrier by adjusting the silicon content of the silicate while maintaining high film conformality and density.

  • Publication number: 20220406782
    Abstract: An example IC device includes a frontend layer and a backend layer with a metallization stack. The metallization stack includes a backend memory layer with a plurality of memory cells with backend transistors, and a layer with a plurality of conductive interconnects (e.g., a plurality of conductive lines) and air gaps between adjacent ones of the plurality of interconnects. Providing air gaps in upper metal layers of metallization stacks of IC devices may advantageously reduce parasitic effects in the IC devices because such effects are typically proportional to the dielectric constant of a surrounding medium. In turn, reduction in the parasitic effects may lead to improvements in performance of, or requirements placed on, the backend memory.
