    摘要: In a method of manufacturing a semiconductor device, an initial structure is provided. The initial structure includes a substrate, a patterned silicon layer, and a covering layer. The substrate has a buried insulator layer formed thereon. The patterned silicon layer is formed on the buried insulator layer. The covering layer is formed on the patterned silicon layer. A first layer is formed on the initial structure. Part of the first layer is removed with an etching process, such that a sidewall portion of the patterned silicon layer is exposed and such that a remaining portion of the first layer remains at a corner where the patterned silicon layer interfaces with the buried insulator layer. An oxide liner is formed on the exposed sidewall portion. A recess may be formed in the buried insulator layer (prior to forming the first layer) and may extend partially beneath the patterned silicon layer.

    摘要: A method for forming a field effect transistor includes: forming a conductive region on an isolation layer formed on a substrate, and a cap dielectric layer on the conductive region; forming a sacrificial dielectric layer over the isolation layer and the cap dielectric layer, and on sidewalls of the conductive region; removing a portion of the sacrificial dielectric layer on the cap dielectric layer; removing the cap dielectric layer; removing remaining portions of the sacrificial dielectric layer; forming a gate on the conductive region; and forming source/drain (S/D) regions within the conductive region and adjacent to the gate. A field effect transistor includes a conductive region over an isolation layer formed on a substrate, the conductive region being substantially without undercut at the region within the isolation layer beneath the conductive region; a gate on the conductive region; and S/D regions within the conductive region and adjacent to the gate.

    摘要: A FinFET split gate EEPROM structure includes a semiconductor substrate and an elongated semiconductor fin extending above the substrate. A control gate straddles the fin, the fin's sides and a first drain-proximate portion of a channel between a source and drain in the fin. The control gate includes a tunnel layer and a floating electrode over which are a first insulative stratum and a first conductive stratum. A select gate straddles the fin and its sides and a second, source-promixate portion of the channel. The select gate includes a second insulative stratum and a second conductive stratum. The insulative strata are portions of a continuous insulative layer covering the substrate and the fin. The conductive strata are electrically continuous portions of a continuous conductive layer formed on the insulative layer.
