What it is

The Applied Materials Centura DPS 2 Poly Etcher is a poly etcher manufactured by Applied Materials. The model is part of the Centura DPS 2 series of plasma etch systems.[1][2][3][4][5]

How it works

General reference — not yet source-verified

The tool operates at low pressure to maintain directional ion bombardment and uses process gases such as chlorine or bromine-containing compounds to etch polysilicon. Endpoint detection systems monitor the etch process to stop at the underlying layer.

Where it fits in the process flow

General reference — not yet source-verified

The poly etch step is a critical part of front-end-of-line (FEOL) processing after polysilicon deposition and photolithographic patterning of the gate electrode. The Centura DPS 2 Poly Etcher is used to define the polysilicon gates of CMOS transistors.

Upstream processes include polysilicon chemical vapor deposition (CVD) and resist coating/exposure. Downstream steps include resist stripping, post-etch cleaning, and oxidation or spacer deposition. The etch must produce vertical sidewalls with tight critical dimension control.

Applications

General reference — not yet source-verified

The primary application of the Centura DPS 2 Poly Etcher is the anisotropic etching of polycrystalline silicon (polysilicon) for gate electrode formation in CMOS logic and memory devices.

The tool can also be used to etch other silicon-based films such as amorphous silicon or poly-SiGe for specialized device structures, as well as for etching polysilicon in capacitor plates or interconnects.
