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.

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.
