IBM has unveiled chip technology that could help extend Moore’s Law another decade

IBM unveiled a prototype chip on Tuesday featuring approximately 100 billion transistors within a fingernail-sized area, doubling the density of its 2021 state-of-the-art technology. This new nanostack architecture vertically stacks transistors in two layers on a silicon chip, a significant advancement that Jay Gambetta, director of IBM Research, described as a "meaningful leap forward." This innovation aims to extend the principles of Moore's Law, which has guided semiconductor development for over 50 years by shrinking transistors. As transistors approach atomic scales, where quantum effects become problematic, the industry is shifting towards building upwards. Gambetta anticipates that chips utilizing nanostacking will become prevalent in data centers within a decade, potentially improving energy management. Dan Hutcheson, vice chair of TechInsights, stated that this development could add "another 10, 15 years on the roadmap" for chip technology. IBM reports that chips designed with this new approach can achieve 50% more work in the same timeframe and offer up to 70% greater energy efficiency compared to its previous architecture. IBM plans to collaborate with semiconductor manufacturers to produce chips based on this nanostacking technology.
