What it is

The Lam 9400 SE is a poly etcher used in semiconductor manufacturing.[1]

How it works

General reference — not yet source-verified

The system typically includes a wafer handling robot, multiple process chambers for increased throughput, and endpoint detection to stop etching precisely when the underlying layer is reached. Temperature and pressure controls maintain process stability.

Where it fits in the process flow

General reference — not yet source-verified

Poly etchers are used in the front-end-of-line portion of semiconductor fabrication, following polysilicon deposition and photolithographic patterning. The polysilicon layer is often deposited via low-pressure chemical vapor deposition over a thin gate oxide. After etching, the remaining photoresist is stripped, and subsequent processing includes oxidation, doping, and dielectric deposition.

Applications

General reference — not yet source-verified

In advanced nodes, poly etching may also be applied to polycide or silicide stacks where a metal silicide layer is formed on top of polysilicon. The process chemistry is adapted to achieve selectivity over the underlying gate oxide.
