摘要： In a vertical dynamic memory cell, monocrystalline semiconductor material of improved quality is provided for the channel of an access transistor by lateral epitaxial growth over an insulator material (which complements the capacitor dielectric in completely surrounding the storage node except at a contact connection structure, preferably of metal, from the access transistor to the storage node electrode) and etching away a region of the lateral epitaxial growth including a location where crystal lattice dislocations are most likely to occur; both of which features serve to reduce or avoid leakage of charge from the storage node. An isolation structure can be provided in the etched region such that space is provided for connections to various portions of a memory cell array.

摘要： A semiconductor fin having a doping of the first conductivity type and a semiconductor column are formed on a substrate. The semiconductor column and an adjoined end portion of the semiconductor fin are doped with dopants of a second conductivity type, which is the opposite of the first conductivity type. The doped semiconductor column constitutes an inner electrode of a capacitor. A dielectric layer and a conductive material layer are formed on the semiconductor fin and the semiconductor column. The conductive material layer is patterned to form an outer electrode for the capacitor and a gate electrode. A single-sided halo implantation may be performed. Source and drain regions are formed in the semiconductor fin to form an access transistor. The source region is electrically connected to the inner electrode of the capacitor. The access transistor and the capacitor collectively constitute a DRAM cell.

摘要： A dielectric mandrel structure is formed on a single crystalline semiconductor layer. An amorphous semiconductor material layer is deposited on the physically exposed surfaces of the single crystalline semiconductor layer and surfaces of the mandrel structure. Optionally, the amorphous semiconductor material layer can be implanted with at least one different semiconductor material. Solid phase epitaxy is performed on the amorphous semiconductor material layer employing the single crystalline semiconductor layer as a seed layer, thereby forming an epitaxial semiconductor material layer with uniform thickness. Remaining portions of the epitaxial semiconductor material layer are single crystalline semiconductor fins and thickness of these fins are sublithographic. After removal of the dielectric mandrel structure, the single crystalline semiconductor fins can be employed to form a semiconductor device.
