    摘要: A memory device comprising a vertical transistor includes a digit line that is directly coupled to the source regions of each memory cell. Because an electrical plug is not used to form a contact between the digit line and the source regions, a number of fabrication steps may be reduced and the possibility for manufacturing defects may also be reduced. In some embodiments, a memory device may include a vertical transistor having gate regions that are recessed from an upper portion of a silicon substrate. With the gate regions recessed from the silicon substrate, the gate regions are spaced further from the source/drain regions and, accordingly, cross capacitance between the gate regions and the source/drain regions may be reduced.

    摘要: One-transistor (1T) capacitor-less DRAM cells each include a MOS transistor having a bias gate layer that separates a floating body region from a base substrate. The MOS transistor functions as a storage device, eliminating the need of the storage capacitor. Logic “1” is written to and stored in the storage device by causing majority carriers (holes in an NMOS transistor) to accumulate and be held in the floating body region next to the bias gate layer, and is erased by removing the majority carriers from where they are held.

    摘要: Integrated circuits and methods of forming field effect transistors are disclosed. In one aspect, an integrated circuit includes a semiconductor substrate comprising bulk semiconductive material. Electrically insulative material is received within the bulk semiconductive material. Semiconductor material is formed on the insulative material. A field effect transistor is included and comprises a gate, a channel region, and a pair of source/drain regions. In one implementation, one of the source/drain regions is formed in the semiconductor material, and the other of the source/drain regions is formed in the bulk semiconductive material. In one implementation, the electrically insulative material extends from beneath one of the source/drain regions to beneath only a portion of the channel region. Other aspects and implementations, including methodical aspects, are disclosed.
