Chipmakers Turn to 3‑D Stacking as Moore’s Law Slows

The semiconductor industry is confronting the slowing of Moore’s Law. Major chipmakers are shifting focus from traditional scaling to 3‑D stacking techniques. Stacking involves layering multiple chip dies to increase density without shrinking transistors. This approach promises higher performance and better power efficiency. Companies are investing in new manufacturing processes to enable reliable stack integration. Analysts view stacking as a key path to sustain computing growth beyond transistor scaling. The transition may reshape product roadmaps for servers, mobile devices, and AI hardware. Industry observers will monitor early stack‑based products for market acceptance.
