Invention Description/ Abstract:

The microelectronic industry has reaped significant benefits from MOSFET miniaturization during the last three decades. The ability to fit hundreds of millions of transistors on a single chip has been enabled by the reduction of transistors to diameters below 100 nm. End users and, above all, the semiconductor industry have benefited from the improved functionality and lower cost of a wide range of integrated circuits and systems. (http://userweb.eng.gla.ac.uk/fikru.adamu-lema/Chapter_02.pdf, n.d.). MOSFET is an abbreviation for a metal-oxide-semiconductor field-effect transistor. MOSFETs are typically three-terminal devices having gate, drain, and source connections. A voltage applied to the gate terminal controls current conduction between the drain and the source. MOS transistor channel lengths have been halved every two or three years for the past 20 years, resulting in a virtuous cycle of rising packing density (more complex electronic devices), improving performance (higher clock frequencies), and lowering prices per unit silicon surface.

Invention Technical Description

Nano-scale MOSFET’s drain and source series resistance and capacitance by oxide thickness not only have a big impact on device attributes and performance, but they're also important factors for technological process monitoring, as well as lifespan and reliability. High resistance and capacitance in a semiconductor can lead to self-healing. The analysis considering, the main effect of self-heating is saturation velocity, vertical/lateral electric field and electron mobility. Adjust and analysing the direct parameter which is channel length and oxide thickness, can reduce the thermal resistance to reduce the self-heating effect (SHE) of Nanoscale MOSFET. The thermal resistance Rth of MOSFET will be simulated with MATLAB will be done in future work.
