NF3
The main raw materials of NF3 gas are hydrofluoric acid and ammonia.
We provide NF3 boasting a purity of more than 99.99%(5N) through EVHT response
and cryogenic purification.
NF3 gas is mainly used for cleaning CVD chambers and
etching semiconductors during the semiconductor and display manufacturing processes.
Smart Factory-based NF3 production facilities for safety and quality enhancement
The Neochem NF3 production process uses smart factory technology to detect anomalies in a facility and monitor the process and quality data in real-time for safe and stable operation and maintains the best quality without safety accidents.
In recognition of its quality and supply stability, high-purity products produced with these advanced technologies are supplied to major semiconductor and display customers as well as international customers, including Taiwan, Japan, the United States, Europe, and Southeast Asia.

High-purity
20% F2/N2
We produce high-purity F2 gas through electrolysis. By mixing F2 gas with high purity N2, we produce high purity 20% F2/N2 independently. 20% F2/N2 is used for cleaning the chamber of the semiconductor equipment, LP_CVD(Low-Pressure Chemical Vapor Deposition).
Manufacturing capacity of F2 mixed gases
Various impurities generated during the production of F2 through the hydrofluoric acid response of electrolysis are purified with cryogenic distillation, producing 99.999% F2. We supply F2/N2 products in a uniform concentration of 20%, utilizing an automated blending facility.

Other High-purity Gases
Neochem PU has independently developed deuterium gas (D2 gas) and high-purity gas (CI2 and HCI gas), and will continue to add a variety of products to our portfolio.
Cl2, HCl
Participating in a national project in combination with a semiconductor client, we successfully localized specialty gases, which were once imported from Japan, and is now used for Si etching in domestic semiconductor processes.
D2
By applying Neochem PU’s exclusive electrolysis technology based on D2O, a strategic material, we successfully localized it for the first time in Korea.
D2 is used in the heat treatment process of the semiconductor wafer and optical cable to extend service life and enhance performance.
