The semiconductor industry reached a major milestone recently when IBM Research,the research and development division of International Business Machines Corporation(IBM),demonstrated what it billed as“the world\'s first 2 nm chip”in May 2021(Fig.1)[1].The test chip uses a breakthrough technology called stacked nanosheets to achieve new levels of transistor density(transistors per square millimeter),paving the way for faster,more energy-efficient semiconductors.
