In September 2026 GlobalFoundries patented semiconductor gate layouts for controlling spin-based quantum dots in quantum computing hardware.
Abstract
The present disclosure relates to semiconductor structures and, more particularly, to quantum dot structures and methods of manufacture. The structure includes: a plurality of barrier gates; a plurality of spin qubit gates interdigitated with the plurality of barrier gates; and access gates on opposing sides of the plurality of barrier gates.
