| 摘要 |
A charge-retaining transistor includes a control gate and an inter-gate dielectric alongside the control gate. A charge-storage node of the transistor includes first semiconductor material alongside the inter-gate dielectric. Islands of charge-trapping material are alongside the first semiconductor material. An oxidation-protective material is alongside the islands. Second semiconductor material is alongside the oxidation-protective material, and is of some different composition from that of the oxidation-protective material. Tunnel dielectric is alongside the charge-storage node. Channel material is alongside the tunnel dielectric. Additional embodiments, including methods, are disclosed. |
