- The fabrication and characterization of nanoscale n- and p-type multi-wire metal-oxide semiconductor field effect transistors (MOSFETs) with a triple gate structure on silicon-on-insulator material (SOI) is described in this paper. Experimental results are compared to simulation with special emphasis on the influence of channel width on the subthreshold behavior. Experiment and simulation show that the threshold voltage depends strongly on the wire width at dimensions below 100 urn. It is further shown that the transition from partial to full channel depletion is dependent on channel geometry. Finally, an increased on-current per chip area is demonstrated for triple-gate SOI MOSFETs compared to planar SOI devices. (C) 2003 Elsevier Science B.V. All rights reserved.

- The fabrication of n-type multi-wire MOSFETs on SOI material with triple-gate structures is presented. The output and transfer characteristics of devices with a gate length of 70 nm and a MESA width of 22 nm demonstrate clearly the suppression of short channel effects (SCE). In addition, these triple-gate structures are compared with planar SOI devices of comparable dimensions. The influence of biasing the substrate (back gate) is analyzed and compared to simulation data.

- The fabrication and characterization of triple-gate p-type metal-oxide semiconductor field effect transistors (p-MOSFETs) on SOI material with multiple channels is described. To demonstrate the beneficial effects of the triple-gate structure on scaling, output and transfer characteristics of 70nm printed gate length p-MOSFETs with 22nm MESA width are presented. The geometrical influence of triple-gate MESA width on subthreshold behavior is investigated in short- and long channel devices. The temperature dependence of subthreshold characteristics is discussed.

- The influence of the potent L-type Ca[2+] channel antagonist Nimodipine on spinal cord evoked potentials (SCEP) and axonal injury following trauma to the spinal cord was examined in a rat model. Spinal cord injury (SCI) was produced by an incision into the right dorsal horn of the T10-11 segments under urethane anaesthesia (1.5 g/kg, i.p.). SCEPs were recorded by epidural electrodes placed over the T9 (rostral) and T12 (caudal) segments after stimulation of the right tibial and sural nerves. SCI induced a pronounced decrease of the SCEP negative amplitude in the rostral (T9) recordings immediately after trauma. Axonal injury seen as degradation of myelin basic protein (MBP) immunostaining and myelin vesiculation at the ultrastructural level was most pronounced at 5 h. Continuous administration of Nimodipine (2 microg/kg/min, i.v.) from 30 min prior to injury until sacrifice markedly attenuated the changes in SCEP amplitude and latency. Axonal damage, loss of MBP, and myelin vesiculation were much less evident in the nimodipine treated traumatised rats. These observations suggest that Ca[2+] channels play an important role in the trauma induced alterations in SCEP and axonal injury, and indicate a therapeutic value of Ca[2+] blockers in SCI.
