  • Publication number: 20210183850
    Abstract: Embodiments disclosed herein include semiconductor devices and methods of forming such devices. In an embodiment, a semiconductor device comprises a semiconductor substrate and a source. The source has a first conductivity type and a first insulator separates the source from the semiconductor substrate. The semiconductor device further comprises a drain. The drain has a second conductivity type that is opposite from the first conductivity type, and a second insulator separates the drain from the semiconductor substrate. In an embodiment, the semiconductor further comprises a semiconductor body between the source and the drain, where the semiconductor body is spaced away from the semiconductor substrate.

  • Publication number: 20210167180
    Abstract: Disclosed herein are transistor arrangements of field-effect transistors with dual thickness gate dielectrics. An example transistor arrangement includes a semiconductor channel material, a source region and a drain region, provided in the semiconductor material, and a gate stack provided over a portion of the semiconductor material that is between the source region and the drain region. The gate stack has a thinner gate dielectric in a portion that is closer to the source region and a thicker gate dielectric in a portion that is closer to the drain region, which may effectively realize tunable ballast resistance integrated with the transistor arrangement and may help increase the breakdown voltage and/or decrease the gate leakage of the transistor.

  • Publication number: 20200403007
    Abstract: Embodiments include diode devices and transistor devices. A diode device includes a first fin region over a first conductive region and an insulator region, and a second fin region over a second conductive and insulator regions, where the second fin region is laterally adjacent to the first fin region, and the insulator region is between the first and second conductive regions. The diode device includes a first conductive via on the first conductive region, where the first conductive via is vertically adjacent to the first fin region, and a second conductive via on the second conductive region, where the second conductive via is vertically adjacent to the second fin region. The diode device may include conductive contacts, first portions on the first fin region, second portions on the second fin region, and gate electrodes between the first and second portions and the conductive contacts.

  • Publication number: 20200235249
    Abstract: This disclosure illustrates a FinFET based dual electronic component that may be used as a capacitor or a resistor and methods to manufacture said component. A FinFET based dual electronic component comprises a fin, source and drain regions, a gate dielectric, and a gate. The fin is heavily doped such that semiconductor material of the fin becomes degenerate.
