  • Patent number: 12672308
    Abstract: An example thin-film transistor includes a source and a gate. The source includes a body of source metal and a body of capacitance-tuning material disposed on the body of source metal. The body of capacitance-tuning material is configured to control a capacitance between the source and the gate. A drain of the thin-film transistor may also include a body of capacitance-tuning material. Capacitance-tuning material may be provided outside the source/drain, for example, adjacent a gate dielectric material. The thin-film transistor may further include a body of reducing material to draw oxygen out of other materials of the thin-film transistor. The thin-film transistor may further include a body of hardmask material used during the making of the thin-film transistor.

  • Publication number: 20260136592
    Abstract: A oxide semiconductor channel stack for semiconductor devices having an oxide semiconductor channel layer, an optional mediating material layer formed over the oxide semiconductor channel layer and a setting layer formed over the mediating material layer, if present, or over the oxide semiconductor channel layer. The setting layer draws surplus oxygen atoms from an adjacent region of the oxide semiconductor to reduce defects therein, thus increasing the current carrying capacity through a channel formed in the oxide semiconductor channel layer. The setting layer can also serve as a contact, such as a gate contact, or a separate metal layer can be formed over the setting layer to serve as a contact.

  • Publication number: 20260120081
    Abstract: A method is disclosed. The method includes transmitting a verification request comprising a wallet account identifier associated with a digital wallet to a smart contract on a blockchain network or a smart contract application associated with the smart contract. The smart contract or the smart contract application verifies the wallet account identifier using a blockchain on the blockchain network. The method also includes receiving from the smart contract on the blockchain network or the smart contract application, a verification response verifying the wallet account. The method further includes initiating transmitting to an authorizing entity computer, an authorization request message comprising a credential associated with the wallet account identifier.

  • Publication number: 20260059793
    Abstract: In a thin-film transistor, a body of tuning material is provided between a substrate and a body of channel material. The body of tuning material removes undesirable chemical species from the body of channel material, a body of gate dielectric material, or both the body of channel material and the body of gate dielectric material. A body of blocking material may be provided to inhibit such tuning that may be caused by a body of gate material.

  • Publication number: 20260032940
    Abstract: A thin-film transistor includes a source including a body of source material and a source carrier reservoir formed of reservoir material, a drain, and a layer of channel material positioned between source and the drain. A hardmask material may be used to pattern the source and drain. Remains of the hardmask may form the source carrier reservoir. The channel material and the reservoir material may be the same material, such as tin oxide.
