Etching gases etch the shape of a space for circuit in the semiconductor prior to the circuit formation of semiconductor. They are in high demand as they are essential in achieving greater precision in 3D structures.

  • MonofluoromethaneCH3F

    CH3F, an etching gas for nitride films in 3D NAND flash memory devices, is becoming more widespread with the increase of 3D NAND use. SK materials is the first and only manufacturer of CH3F in Korea.

  • HexafluorobutadieneC4F6

    C4F6 is used in the etching of oxide films for miniaturized DRAMs and 3D NAND flash memory devices. C4F6 has seen a significant increase in demand.

  • DifluoromethaneCH2F2

    CH2F2, along with CH3F, is a gas used in etching nitride films in NAND flash memory devices. It has been widely utilized since 3D NAND has been increasingly used in the recent.

  • Hydrogen bromideHBr

    HBr is a gas used in semiconductor etching processes. It has excellent precision / vertical etching capabilities, whose usage is increasing due to the sophistication of semiconductors.


Environmental Strategy

Environmental Compliance System

SK resonac has established its own environmental procedures in the fields of air, water, and waste, etc. in order to comply with state environmental laws and regulations, such as the Clean Air Conservation Act and the Water Environment Conservation Act, and regularly checks the level of implementation.
In particular, in 2021, SK resonac strengthened its own compliance monitoring process to monitor compliance with SHE laws and its internal regulations. The company updated its internal compliance scorecard for environmental laws and regulations to reflect revisions to laws, recent SHE issues, and other companies’ violations of laws, and ceach business site conducted a self-evaluation and the environmental management team verified the results. In addition, SK resonac manages pollutants emitted from its business site by applying stricter self-management standards than the legal emission standards. Through this, we expect to prevent violations of laws and minimize impact on the environment.
