The SPTS Omega fxP is an ICP etcher. The SPTS Omega fxP is categorized as an Etch tool. The SPTS Omega fxP is manufactured by SPTS, also known as STS.[1][2]
What it is
General reference — not yet source-verifiedThe Omega fxP is a plasma etcher used in semiconductor manufacturing. The equipment is manufactured by SPTS (formerly STS). The Omega fxP belongs to the class of dry etch tools that remove material from a wafer surface using a plasma process.
How it works
General reference — not yet source-verifiedPlasma etchers create a low-pressure environment in a process chamber and introduce reactive gases. An electric field ionizes the gases to form a plasma, which contains energetic ions and chemically reactive radicals. The physical bombardment of ions and chemical reactions with radicals selectively remove material from the wafer according to a patterned mask.
Where it fits in the process flow
General reference — not yet source-verifiedThe Omega fxP is used in the etch step of semiconductor fabrication, after photolithography has defined patterns in a resist layer. The etcher transfers those patterns into the underlying thin films, such as dielectrics or conductors. Downstream steps include resist stripping, cleaning, and subsequent deposition or metallization.
Applications
General reference — not yet source-verifiedThe Omega fxP can be used to etch a variety of materials commonly encountered in semiconductor device fabrication, including silicon, silicon dioxide, silicon nitride, and certain metals. Applications range from front-end-of-line (FEOL) trench and contact etching to back-end-of-line (BEOL) via and interconnect structuring.
