Semiconductor Gas Delivery Solution — LAM RESEARCH 715-031199-001 | TS-4000Z Series
Where This Product Is Used
The LAM RESEARCH 715-031199-001 (alt P/N: 839-031209-001) Valve Weldment Manifold is a precision gas-path assembly deployed in high-volume semiconductor fabs running Lam Research TS-4000Z-16 CVD and ALD process chambers. It serves as the central gas-distribution node that routes, isolates, and sequences precursor and purge gases to the process chamber with leak-tight integrity.
- CVD / ALD Thin-Film Deposition — Controls precursor gas sequencing for dielectric and metal film deposition on 200 mm / 300 mm wafers.
- Etch Gas Panels — Used as an isolation manifold in plasma etch modules requiring ultra-high-purity gas switching.
- Diffusion Furnace Gas Boxes — Integrates into oxidation and annealing gas-delivery stacks where repeatable valve actuation is critical.
- Preventive Maintenance (PM) Replacement — Standard PM BOM item for TS-4000Z-16 chambers; replaced on scheduled intervals to maintain process baseline.

Why Engineers Specify This Model
- OEM-Exact Geometry — Weld-formed manifold body matches original Lam tooling drawings; no field modification required for drop-in replacement.
- Multi-P/N Cross-Reference — Covers six interchangeable part numbers (715-031199-001, 839-031209-001, M120, MC-31049, MC-31151P, 1181-000569-13), simplifying procurement across different fab BOM revisions.
- Process Baseline Protection — Replacing with an OEM-equivalent weldment preserves gas-flow Cv and leak-up rate, protecting wafer yield.
- Reduced Downtime — Ready-to-install assembly eliminates on-site welding or sub-assembly work, cutting chamber-down time.
- Traceability — Each unit ships with inspection records and, where available, original Lam traveler documentation.

Application-Specific FAQ
Q: Is 839-031209-001 a direct replacement for 715-031199-001?
A: Yes. Both part numbers reference the same Valve Weldment Manifold assembly; 839-031209-001 is the revised drawing release. They are dimensionally and functionally interchangeable.
Q: Which Lam Research platforms use this manifold?
A: Primarily the TS-4000Z-16 CVD/ALD module. Cross-reference P/Ns (M120, MC-31049, MC-31151P) may also appear in adjacent Lam gas-box configurations — confirm with your tool’s BOM before ordering.
Q: Can Konmask supply the full gas-delivery sub-assembly?
A: Yes. We can source and kitting the complete gas-box assembly including MFCs, valves, fittings, and filters. Contact us with your full BOM for a consolidated quote.
Q: What is the typical PM interval for this part?
A: Lam-recommended PM intervals vary by process chemistry and chamber utilization. Consult your TS-4000Z-16 PM manual or contact Konmask’s applications team for guidance.
Q: Do you offer warranty on refurbished units?
A: Refurbished units carry a 90-day functional warranty. New OEM units carry the original manufacturer warranty where applicable.
