  • Publication number: 20220409886
    Abstract: A neural stimulator system which generates stimulation from an implantable stimulator circuit which generates stimulation outputs which mimic biological signals. The user/operator can select stimulation generated from recorded waveforms, or by selecting the characteristics for generating stimulation based on randomized inter-pulse-intervals (IPI). A control unit controls the operation of the implantable stimulator circuit, and receives sets of stimulation parameters based on user input from a user input device executing application specific programming.

  • Publication number: 20220246609
    Abstract: An integrated circuit die includes a FinFET transistor. The FinFET transistor includes an anti-punch through region below a channel region. Undesirable dopants are removed from the anti-punch through region during formation of the source and drain regions. When source and drain recesses are formed, a layer of dielectric material is deposited in the recesses. An annealing process is then performed. Undesirable dopants diffuse from the anti-punch through region into the layer of dielectric material during the annealing process. The layer of dielectric material is then removed. The source and drain regions are then formed by depositing semiconductor material in the recesses.
