摘要： A structure for use as a MOSFET employs an SOI wafer with a SiGe island resting on the SOI layer and extending between two blocks that serve as source and drain; epitaxially grown Si on the vertical surfaces of the SiGe forms the transistor channel. The lattice structure of the SiGe is arranged such that the epitaxial Si has little or no strain in the direction between the S and D and a significant strain perpendicular to that direction.

摘要： A novel transistor structure for a DRAM cell includes two deep trenches, one trench including a vertical storage cell for storing the data and the second trench including a vertical control cell for controlling the p-well voltage, which, in effect, places part of the p-well in a floating condition thus decreasing the threshold voltage as compared to when the vertical pass transistor is in an off-state. This enables the transistor to exhibit increased gate overdrive and drive current during an active wordline voltage commonly applied to both gates of the storage and control cells.

摘要： Provision of a body control contact adjacent a transistor and between the transistor and a contact to the substrate or well in which the transistor is formed allows connection and disconnection of the substrate of the transistor to and from a zero (ground) or substantially arbitrary low voltage in accordance with control signals applied to the gate of the transistor to cause the transistor to exhibit a variable threshold which maintains good performance at low supply voltages and reduces power consumption/dissipation which is particularly advantageous in portable electronic devices. Floating body effects (when the transistor substrate in disconnected from a voltage source in the “on” state) are avoided since the substrate is discharged when the transistor is switched to the “off” state. The transistor configuration can be employed with both n-type and p-type transistors which may be in complementary pairs.
