Definition: angstrom era


The period starting in the mid-2020s when the elements of a transistor are smaller than one nanometer. As time progresses, chip technology will be expressed in angstroms (A) rather than nanometers (nm). Intel calls its two nanometer chips 20A to reflect this naming convention (see Intel 20A). See angstrom, ultraviolet light, process technology and Intel node names.
