Applied Angstrom Technology

What Applied Angstrom Technology does

Applied Angstrom Technology (AAT) is a Singapore-headquartered semiconductor process equipment company founded in 2022 that develops atomic layer etching (ALE) tools and complementary plasma and coating subsystems for advanced chip manufacturing. Its core product is a plasma-assisted, layer-by-layer dry etching platform that delivers precise etching profile control at sub-nanometer scale, offered in both anisotropic and isotropic configurations and aimed at 3D logic and memory, silicon photonics, and quantum device manufacturing. Supporting modules include a modular Gas Delivery System at roughly one-third the footprint of traditional systems, a Remote Plasma Source with a proprietary gold hard coating and overhaul service, and a plasma-in-liquid protective coating for chamber components characterized by greater than 2000 HV hardness and greater than 2000 V dielectric breakdown.

AAT opened the Atomic Precision Innovation Center (APIC), an over 10,000 sq ft facility with a Class 100 cleanroom in Yishun, Singapore, in March 2026, marking its transition into integrated design, testing, and pilot production. The company generates revenue through hardware sales of ALE tools and related subsystems and through professional services such as remote plasma source overhauls, and it pursues enterprise chip manufacturers directly via field sales, with Micron and GlobalFoundries named as Singapore-based target accounts. It is backed by iGlobe Partners and Enterprise Singapore and operates a global supplier network spanning Singapore, Taiwan, South Korea, Europe, and the United States.

The company's go-to-market is concentrated in B2B enterprise sales to a narrow set of advanced semiconductor manufacturers, with no publicly disclosed pricing, no disclosed revenue, and no confirmed paying customer logos. AAT has begun layering AI functionality onto its hardware via a Digital Twins software module co-developed with Dutch firm Sioux Technologies, positioning process intelligence and automation as a secondary value-add on top of its precision hardware platform.

Core offering

Applied Angstrom Technology develops and manufactures atomic-layer semiconductor process equipment, centered on Atomic Layer Etching (ALE) tools that perform plasma-assisted layer-by-layer dry etching for sub-nanometer precision. The portfolio also includes an integrated Gas Delivery System, a Remote Plasma Source with proprietary recoating capability, and a Plasma-in-liquid protective coating applied to chamber components for advanced chip manufacturing.

Product overview

Applied Angstrom Technology is a semiconductor equipment company offering a portfolio of precision hardware products centered on Atomic Layer Etching (ALE) technology. The core product is the ALE tool and process, which supports both Anisotropic and Isotropic etching modes for sub-nanometer precision control. Supporting this core are complementary hardware modules: the Gas Delivery System (modular design with high-speed valves for ALE), the Remote Plasma Source (with gold hard coating and overhaul services), and Plasma-in-liquid Coating (proprietary protective coating for semiconductor chamber parts). The company also offers Digital Twins as an AI-assisted software module to enhance ALE precision and intelligence. The products are designed for manufacturing high performance 3D logic and memory chips, silicon photonics chips, and quantum technology for AI infrastructure.

Products and services

• Atomic Layer Etching (ALE) Tool A plasma-assisted layer-by-layer dry etching system that performs sub-nanometer precision etching through a four-step Dose, Purge, Etch, Purge cycle. Offered in Anisotropic (directional) and Isotropic (uniform) configurations for advanced semiconductor manufacturers.
• Gas Delivery System A modular integrated gas system with a compact form factor (1/3 of traditional GDS footprint), semi-standards compliance, and ease of maintenance; features high-speed response valves tuned for ALE processes with high durability and repeatability.
• Remote Plasma Source (RPS) with Overhaul Service Remote Plasma Source unit and complete overhaul service covering inspection, disassembly, replacement parts (re-coating plasma block, consumables, cooling water line cleaning), assembly, and performance testing; uses gold hard coating for higher erosion resistance, higher dissociation rate, and lower process temperature.
• Plasma-in-liquid Protective Coating A proprietary coating service that uses tiny plasma to spread uniformly across surfaces, achieving hardness above 2000 HV, dielectric breakdown voltage above 2000 V, excellent corrosion resistance, and conformal coverage along 3D part contours; designed to protect critical parts inside plasma etching chambers in semiconductor manufacturing.
