While GAAFETs offer numerous advantages, they also present several challenges:
Fabrication complexity: The intricate structure of GAAFETs requires advanced fabrication techniques, which can be costly and complex. Material interface quality: Ensuring high-quality interfaces between different materials is critical for the performance and reliability of GAAFETs. Thermal management: As device dimensions shrink, managing heat dissipation becomes increasingly important to maintain device performance and longevity.
