Quantum tunnelling effects through the gate oxide layer on 7 nm and 5 nm transistors became increasingly difficult to manage using existing semiconductor processes. Single-transistor devices below 7 nm were first demonstrated by researchers in the early 2000s. In 2002, an IBM research team including Bruce Doris, Omer Dokumaci, … chucky lighter
