电脑芯片继续缩水。但是，一层二氧化硅必须至少有四到五个原子厚才能起到绝缘体的作用，这一发现表明，硅基微芯片将在下个世纪初达到小型化的物理极限。
Computer chips continue to shrink. But the discovery that a layer of silicon dioxide must be at least four to five atoms thick to function as an insulator suggests that silicon-based microchips will reach the physical limits of miniaturization early next century.
