What it is

The Lam Research 4520 is an etch tool used in semiconductor manufacturing.[1]

The Lam Research 4520 family includes a rainbow oxide etch configuration and a TCP oxide etch system configuration.[5][2]

How it works

The Lam Research 4520 includes Envision Software, a Hine cassette indexer load and unload, an entrance loadlock, a remote AC panel, and a main chamber with a top actuate clamping system.[1]

Where it fits in the process flow

General reference — not yet source-verified

Etch tools sit in the pattern transfer stage of semiconductor fabrication, after a lithography step defines the areas to be opened and before later process steps build on the etched surface.

Applications

The Lam Research 4520 is used for contact etch, planarization, via etch, trench mask etch, and pad etch.[4]
