Layers of transistor
WebThe gate oxide is the dielectric layer that separates the gate terminal of a MOSFET (metal–oxide–semiconductor field-effect transistor) from the underlying source and drain terminals as well as the conductive channel that connects source and drain when the transistor is turned on. 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, Meikei Ieong and Anda Mocuta fabricated a 6-nanometre silicon-on-insulator (SOI) MOSFET.
