The Lam Alliance A 6 Exelan HPT Dielectric Etch is a semiconductor etching tool for 8-inch wafers. The Lam Alliance A 6 Exelan HPT features Exelan HPT chambers and a 4520 chamber. The Lam Alliance A 6 Exelan HPT was built around 1997.[1]
What it is
How it works
General reference — not yet source-verifiedDielectric etch systems use plasma-based processes to remove dielectric material from a wafer surface in a controlled manner.
Where it fits in the process flow
General reference — not yet source-verifiedDielectric etch systems are used in the fabrication of integrated circuits to create features such as contact holes, vias, and trenches in dielectric layers.
The system typically follows deposition steps that create dielectric films and precedes metallization steps that fill the etched features.
Applications
General reference — not yet source-verifiedThe system is used for etching dielectric materials such as silicon dioxide, silicon nitride, and low-k dielectrics in semiconductor device fabrication.
Applications include the formation of contact holes, via holes, and trench isolation structures in interlayer dielectric films.
