Use left and right arrow keys to seek audio. For roughly six decades, the semiconductor industry has followed a simple and reliable formula: make transistors smaller, pack more of them onto a chip, ...

Forward-looking: For years, the chip industry has chased better performance by shrinking transistors and squeezing more of them onto a flat slice of silicon. That strategy is running into hard limits.

As traditional chip miniaturization slows, researchers have found a way to pack more computing power into the same space by stacking silicon circuits in multiple layers. The new process uses ...
