dc.description.abstract This paper discusses in detail the effect of small geometries on the performance of NMOS transistors fabricated using a 28-nm gate-first CMOS technology. It is shown that the threshold voltage and transconductance of the NMOS transistors increase with the decrease in the channel width, and this effect is enhanced at shorter gate lengths. PMOS transistors show conventional width dependence. The possible physical mechanisms responsible for this anomalous behavior are identified and explained through detailed measurements. A 2-D charge-distribution-based model is proposed to model this anomalous effect. The accuracy of the proposed model is verified by comparing it with the experimental and simulated data. en_US
