(Intel
18Angstroms) As of 2026, Intel 18A is Intel's latest chip technology. Using cutting-edge designs, Intel 18A is the successor to Intel 20A, which was tested but not commercialized. Intel 14A is expected in 2028. See
Intel 14A.
Although initially used for Intel's own x86 processor line, Intel has become a foundry for chip designers and competes directly with TSMC. See
Intel Foundry and
TSMC.
Not Really 18 Angstroms
The angstrom measurements are branding and not physical dimensions. The chip's feature sizes are not 18 and 14 angstroms. Since the 2010s, the nanometer measurements continue to decrease for marketing purposes, not physical sizes. Actual gate lengths are larger. However, the increasingly smaller designations are meaningful because they include improved transistor designs. See

angstrom.
RibbonFET and PowerVias
Intel 18A uses the RibbonFET transistor design and also places the power wires at the bottom of the chip instead of the top where signal wires connect the gates (see
RibbonFET). The PowerVia architecture uses vias from the bottom to the top of the chip and is a major breakthrough in transistor design but also requires more development steps (see
BSPDN). See
