What it is

The Tegal 803 is an inline automatic wafer RF plasma etcher.[1]

How it works

General reference — not yet source-verified

An RF plasma etcher creates a glow discharge by applying radio-frequency power to a process gas at low pressure. The resulting plasma contains ions, electrons, and radicals that react with the wafer surface to etch patterns defined by a mask.

In an inline automatic system, wafers are loaded from a cassette, processed in sequence through a series of chambers or stations, and then unloaded automatically, allowing high-throughput operation.

Where it fits in the process flow

General reference — not yet source-verified

Plasma etching is a pattern-transfer step that follows photolithography in semiconductor fabrication. The etcher removes material from areas not protected by photoresist or a hard mask, transferring the circuit pattern into the underlying layer.

Applications

General reference — not yet source-verified

Plasma etchers are used to etch silicon, silicon dioxide, silicon nitride, and various metals (e.g., aluminum, tungsten) in the manufacture of integrated circuits and microelectromechanical systems.

The Tegal 803, as an RF plasma etcher, would be applicable to both front-end-of-line (FEOL) and back-end-of-line (BEOL) etching processes, including polysilicon gate etching, contact hole formation, and metal interconnect patterning.
