The design and fabrication of N-channel MOS transistors with effective gate lengths of 0.5μm or smaller have been completed at the Semiconductor and Microsystems Fabrication Laboratory at the Rochester Institute of Technology. An NMOS device with Lmask = 0.7μm results in an Leff= 0.5μm. The drive current for this device with supply voltage of 3.5V is 108μA/μm. The sub-threshold slope is 100mV/decade and a DIBL parameter of 29mV/V is reported. An NMOS device withLmask=0.6μm results in an Leff =0.4μm. The drive current for this device with supply voltage of 3.5V is l40μA/μm. The sub-threshold slope is 103mV/decade and a DIBL parameter of 11OmV/V is reported. These are RIT’s first sub-0.5micron MOS transistors.
