Etching the future one atom at a time

Applied Angstrom Technology is the world's first AI-native semiconductor equipment company. The chips that power AI require equipment powered by AI — our PEDSL platform provides sub-angstrom precision for advanced logic, 3D NAND, DRAM and silicon photonics.

01The Thesis

At 3nm and below, atomic layer etch isn't optional. It's the only path.

AI's appetite for compute is rewriting the rules of what a chip must be — and what it takes to build one. Every leading-edge transistor now depends on removing material a single atomic layer at a time, with zero margin for error.

AAT was built clean-sheet, AI-native, for exactly this moment.

001

AI-driven hardware demand

Data centers, GPUs, HBM and silicon photonics are pulling unprecedented volumes of sub-angstrom-precision equipment into the market.

002

ALE is indispensable

Sub-nm profile control for GAA nanosheet release, HAR DRAM/NAND structures and photonic waveguide smoothing. Not negotiable below 7nm.

003

A clean-sheet, AI-native tool

Founders and team with over 100+ years of combined experience in the semiconductor industry — building the first platform designed for AI from day one.

02Our Platform

Neural-network process control visualization
PEDSL ML process loopREAL-TIME

Equipment that learns every cycle.

PEDSL pairs decoupled radical and ion control with a machine-learning process loop that tunes gas flow, power and timing in real time — delivering tighter uniformity and far faster recipe development than any manually tuned legacy tool.
