指甲盖大小的芯片：IBM突破性3D堆叠技术

Computing Tiny chip is size of a fingernail IBM has revealed a powerful chip that packs in twice as many transistors as the current state-of-the-art by adding a second layer of silicon circuitry, reports Matthew Sparkes THERE is a new record for tiny, powerful computer chips. IBM’s prototype chip is the size of a fingernail, yet packs in almost 100 billion transistors – nearly twice as many as the previous state-of-the-art chip – thanks to a three-dimensional technique. The firm says the 10-millimetre- by-15-millimetre chip will offer 70 per cent higher energy efficiency and 50 per cent higher performance than current leading chips, and will be in commercial devices within 10 years. …
