Lam Research ALL IN 1 GAS BOX 571-065780-703 — Overview

The Lam Research 571-065780-703 ALL-IN-1 Gas Box is a semiconductor process gas delivery assembly used in Lam plasma etch systems (especially Lam 2300 / Flex / Jetstream platforms). It integrates gas distribution, safety, and flow control into a single module installed in the tool gas cabinet.

Key Function

This module manages process gases used during plasma etching and deposition, ensuring:

• Ultra-precise gas flow control
• Safe gas isolation and purge
• Integration with tool interlocks and process recipes

Gas boxes are critical subassemblies in semiconductor fabs because process gases (CF₄, SF₆, Cl₂, BCl₃, O₂, Ar, etc.) must be delivered with extremely tight tolerances.

Main Features

Typical configuration of the 571-065780-703 Jetstream gas box includes:

1) Integrated Mass Flow Controllers (MFCs)

• Version -703 is known as the Jetstream gas box with 16 MFC channels.
• Provides multi-gas mixing and recipe flexibility.
• Usually equipped with HORIBA / MKS / STEC MFCs depending on build.

2) All-in-One Gas Panel Design

“ALL-IN-1” means the module integrates:

• Gas inlet manifolds
• Pneumatic valves
• Purge lines (N₂ / Ar)
• Pressure regulators
• Leak detection & interlocks

This reduces installation complexity and improves maintenance speed.

3) Designed for Lam Jetstream Etch Platforms

Used in:

• Lam 2300 Kiyo / Exelan / Flex series
• Plasma etch chambers requiring multi-gas capability

Documentation for Lam 300 mm V2 Flex lists the ALL IN 1 GAS BOX as a standard subsystem in the tool configuration.

Typical Technical Characteristics (industry typical)

Because Lam doesn’t publish open datasheets, specs are usually known from field service and refurbishment listings:
