You must log in to view the full proceedings.

Some semiconductor etch processes utilize HBr or a combination of HBr + Cl2, along with fluorinated greenhouse gases (F-GHGs) such as SF6, CF4, and others. Burn-wet abatement is commonly used to destroy the F-GHGs. A new abatement approach will be discussed for abatement of these materials.
