Abstract:
Systems and methods for forming films on the surface of a substrate are described. The systems possess aerosol generators which form droplets from a liquid solution made from a solvent and a deposition precursor. A carrier gas may be flowed through the liquid solution and push the droplets toward a substrate placed in a substrate processing region. The droplets pass into the substrate processing region and chemically react with the substrate to form films. The temperature of the substrate may be maintained below the boiling temperature of the solvent during film formation. The solvent imparts a flowability to the forming film and enable the depositing film to flow along the surface of a patterned substrate during formation prior to solidifying. The flowable film results in bottom-up gapfill inside narrow high-aspect ratio gaps in the patterned substrate.
Abstract:
A germanium-containing semiconductor device and a method for forming a germanium-containing semiconductor device are described. The method includes providing a germanium-containing substrate, depositing an aluminum-containing diffusion barrier layer on the germanium-containing substrate, depositing a high-k layer on the aluminum-containing diffusion barrier layer, and exposing the high-k layer to atomic oxygen to reduce the equivalent oxide thickness (EOT) of the high-k layer while avoiding oxidizing the germanium-containing substrate. The germanium-containing semiconductor device includes a germanium-containing substrate, an aluminum-containing diffusion barrier layer on the germanium-containing substrate, and a high-k layer on the aluminum-containing diffusion barrier layer, where the high-k layer has been exposed to atomic oxygen to reduce the EOT of the high-k layer while avoiding oxidizing the germanium-containing substrate.
Abstract:
Techniques are disclosed for reducing off-state leakage of fin-based transistors through the use of a sub-fin passivation layer. In some cases, the techniques include forming sacrificial fins in a bulk silicon substrate and depositing and planarizing shallow trench isolation (STI) material, removing and replacing the sacrificial silicon fins with a replacement material (e.g., SiGe or III-V material), removing at least a portion of the STI material to expose the sub-fin areas of the replacement fins, applying a passivating layer/treatment/agent to the exposed sub-fins, and re-depositing and planarizing additional STI material. Standard transistor forming processes can then be carried out to complete the transistor device. The techniques generally provide the ability to add arbitrary passivation layers for structures that are grown in STI-based trenches. The passivation layer inhibits sub-fin source-to-drain (and drain-to-source) current leakage.

Abstract:
Solution processible hardmasks are described that can be formed from aqueous precursor solutions comprising polyoxometal clusters and anions, such as polyatomic anions. The solution processible metal oxide layers are generally placed under relatively thin etch resist layers to provide desired etch contrast with underlying substrates and/or antireflective properties. In some embodiments, the metal oxide hardmasks can be used along with an additional hardmask and/or antireflective layers. The metal oxide hardmasks can be etched with wet or dry etching. Desirable processing improvements can be obtained with the solution processible hardmasks.
