Researchers use lasers and metalenses to align 3D chips with atomic precision

Forward-looking: Researchers at the University of Massachusetts Amherst have developed a laser-based technique to align 3D semiconductor chips, potentially overcoming a longstanding challenge in chip manufacturing. The method employs concentric metalenses to generate holograms that reveal misalignment between chip layers at a much smaller scale than previously possible.

It will have an enormous impact on many US firms, especially Apple, which relies heavily on China to manufacture its iPhones. Trump believes the solution is to start making the handsets in the US, but that would be nearly impossible, especially in the short term. And even if it were, iPhones would likely become much more expensive.
