20230215703 · 2023-07-06 ·

Sealing various machined component parts used in plasma etching chambers using an Atomic Layer Deposition (ALD) coating. By sealing the component parts with the ALD layer, surface erosion/etch caused by repeated exposure to plasma during workpiece fabrication is eliminated or significantly mitigated. As a result, unwanted particle generation, caused by erosion, is eliminated or significantly reduced, preventing contamination within the plasma etching chamber.

ETCHING METHOD AND ETCHING APPARATUS

A technique increases verticality in etching. An etching method is a method for etching a target film with a plasma processing apparatus including a chamber and a substrate support located in the chamber to support a substrate, the substrate support holding a substrate that includes the target film, the target film including a patterned mask film having at least one opening. The etching method includes supplying a process gas containing an HF gas into the chamber, and etching the target film by: generating plasma from the process gas in the chamber with radio-frequency power having a first frequency, and applying a pulsed voltage periodically to the substrate support at a second frequency lower than the first frequency.

Reduction of Br.SUB.2 .and Cl.SUB.2 .in semiconductor processes

One or more embodiments described herein relate to abatement systems for reducing Br.sub.2 and Cl.sub.2 in semiconductor processes. In embodiments described herein, semiconductor etch processes are performed within process chambers. Thereafter, fluorinated greenhouse gases (F-GHGs), HBr, and Cl.sub.2 gases exit the process chamber and enter a plasma reactor. Reagent gases are delivered from a reagent gas delivery apparatus to the plasma reactor to mix with the process gases. Radio frequency (RF) power is applied to the plasma reactor, which adds energy and “excites” the gases within the process chamber. When HBr is energized, it forms Br.sub.2. Br.sub.2 and Cl.sub.2 are corrosive and toxic. However, the addition of H.sub.2O in the plasma reactor quenches the Br.sub.2 and Cl.sub.2 emissions, as the H atoms recombine with the Br atoms and the Cl atoms to form HBr and HCl. HBr and HCl are readily water-soluble and removed through a wet scrubber.
