Image Generated With GPT Image 2.0 Semiconductor Scaling Is Becoming A System Problem The semiconductor industry is entering a phase in which scaling is no longer defined solely by transistor density. For decades, advances in lithography and process scaling have improved performance, power efficiency, and integration density. Smaller transistors enabled greater computing capability within the same silicon area, supporting the growth of cloud computing, mobile devices, and artificial intelligence systems. That model is now under increasing pressure. Advanced nodes continue to improve transistor density, but the system-level benefits no longer scale linearly. Power density has become more difficult to manage, reticle size limitations constrain die growth, and manufacturing complexity continues to rise. At the same time, AI workloads are reshaping compute infrastructure by demanding massive data movement across processors,
