APPLIED MATERIALS 0050-04414 0161-31275 H21-03118 M-832HG-S 1139039 RF Coil Inner – Semiconductor Process Chamber Component
When an RF coil inner fails inside a CVD or etch process chamber, the consequences are immediate and costly: plasma uniformity collapses, wafer yield drops, and the entire production line faces unplanned downtime. In high-volume semiconductor fabs running 24/7, every hour of unscheduled maintenance translates directly into lost revenue and missed delivery commitments. The RF coil inner is not a peripheral accessory — it is the electromagnetic heart of the process chamber, and its integrity is non-negotiable.
The APPLIED MATERIALS part number 0050-04414 (cross-references: 0161-31275, H21-03118, M-832HG-S, 1139039) is an OEM-specified RF Coil Inner designed for Applied Materials process equipment. Applied Materials is the world’s leading supplier of semiconductor manufacturing equipment, and this component is engineered to the exacting tolerances required for plasma-based deposition and etch processes. Sourcing a genuine or OEM-equivalent replacement is critical to restoring process stability and maintaining chamber qualification.
