What are the Challenges in Developing Nanoscale MOSFETs?
Developing nanoscale MOSFETs involves overcoming several technical hurdles. These include:
Quantum Tunneling: As the size of the transistor decreases, electrons can tunnel through the gate oxide, leading to leakage currents. Heat Dissipation: Smaller transistors generate more heat per unit area, necessitating advanced cooling solutions. Fabrication Techniques: Producing nanoscale features with precision requires cutting-edge lithography and etching processes. Material Limitations: Traditional silicon may not always be suitable for nanoscale devices, prompting the exploration of alternative materials like graphene and carbon nanotubes.
