Channel Dimension-Dependent Electrical Study for Performance Analysis of Low-dimensional n-MOSFET Device

ABSTRACT

This paper describes the channel dimension-dependent performance analysis of n-MOSFET. Channel dimension of a MOSFET plays an important role in fabricating electronic devices for sensing applications. So, the detailed investigations are essentially required prior to electronic sensor fabrication. In this regard, we carried out a study upon various sets of electrodes with different channel dimensions throughout this work. To complete such a study, we investigated the effect of channel length/width upon electrical performance of n-MOSFET. HSPICE software was utilized for simulation of the work prior to device fabrication. Experimental validation was carried out using five sets of photolithographically patterned electrodes. The study upon various sets of channel dimension (15, 30 µm) shows the best results as per our investigation.
