Silicon has been the cornerstone of modern electronics for over 75 years, but as technology advances, the need to move beyond silicon is becoming apparent due to limitations in power efficiency and miniaturization. Alternative materials like wide bandgap semiconductors (GaN and SiC), 2D materials (TMDs and graphene), and bismuth are being explored as replacements. These materials offer advantages such as higher efficiency, faster switching speeds, and improved thermal management over silicon. While silicon may not be entirely replaced, newer semiconductor materials are expected to enhance chip performance in the next 10-15 years through stacking and hybrid integration technologies. Yield management solutions will play a crucial role in optimizing the production of these new materials.
