The Lam Research Rainbow 4500 Dry is a dry etcher produced by Lam Research. The Rainbow 4500 Dry processes 6-inch wafers.[1]
What it is
How it works
General reference — not yet source-verifiedDry etch tools remove material from a wafer with a plasma-based process rather than liquid chemistry. Dry etching uses a process chamber, controlled gas flow, and energized species to shape patterned films after lithography has opened features on the wafer.
An etch tool transfers the mask pattern into exposed material by directing the reactive plasma to the wafer surface. The process can be tuned for anisotropic removal when the target process requires directional sidewalls.
Where it fits in the process flow
General reference — not yet source-verifiedA dry etch system sits after lithography and before later wafer-processing steps that depend on the etched pattern. The tool is used when the process flow needs selective removal of exposed material from patterned areas.
Applications
General reference — not yet source-verifiedDry etch equipment is used for patterned material removal in semiconductor fabrication. The class is used for transferring circuit features into films on the wafer surface.
