713-028553-102 3161911V01 9011496V02 TPA175D-P10-L400-M-M750W Product Description

The Lam Research 713-028553-102 (cross-references: 3161911V01, 9011496V02) is a precision-engineered confinement ring designed for the TPA175D TCP (Transformer-Coupled Plasma) etch platform. Within a semiconductor process control architecture, the confinement ring is not a passive consumable — it is a critical plasma boundary component that directly governs etch uniformity, process repeatability, and chamber-to-chamber matching across multi-tool deployments. Its dimensional stability, material integrity, and system-matched geometry are prerequisites for maintaining process window consistency at the control layer.

In high-volume manufacturing environments — including logic, memory, and advanced packaging fabs — the TPA175D platform operates as part of a tightly integrated etch module stack. The 713-028553-102 confinement ring interfaces directly with the chamber liner, focus ring, edge ring, and upper electrode assembly, forming the plasma confinement boundary that defines ion flux distribution and radical density at the wafer edge. Any dimensional deviation or material degradation in this component propagates immediately into etch rate non-uniformity, CD (critical dimension) shift, and increased within-wafer variation — outcomes that cascade through downstream lithography, deposition, and metrology steps.

The 713-028553-102 confinement ring operates within a layered process control architecture that spans multiple interdependent subsystems. Understanding its role requires mapping it against the full chamber and tool-level control stack:

Chamber Control Layer: The TPA175D TCP etch system is governed by a Lam Research SPARC-based process controller that manages RF power delivery, gas flow, pressure regulation, and endpoint detection in real time. The confinement ring's plasma boundary geometry directly influences the feedback signals received by the RF match network and the endpoint detection module — making its dimensional accuracy a prerequisite for stable closed-loop process control.

RF Power and Match Network Layer: The Lam Research RF generator assembly (typically paired with the TCP coil and bias RF subsystem on TPA175D) relies on a stable plasma impedance environment. The confinement ring defines the outer plasma boundary, and any erosion or misalignment shifts the effective plasma load seen by the match network, degrading RF coupling efficiency and increasing reflected power events. Maintaining OEM-specification confinement ring geometry is therefore essential for RF system stability.

Gas Distribution and Pressure Control Layer: The confinement ring works in concert with the chamber liner, gas injection ring, and throttle valve assembly to maintain the correct process pressure profile across the wafer surface. In multi-zone gas delivery configurations — common in advanced logic etch applications — the confinement ring's slot geometry and gap dimensions must be held to tight tolerances to prevent gas bypass and pressure non-uniformity.

Focus Ring and Edge Ring Assembly: The 713-028553-102 interfaces mechanically and functionally with the focus ring (silicon or quartz), the edge ring, and the electrostatic chuck (ESC) assembly. These components collectively define the ion bombardment angle and energy distribution at the wafer edge. A worn or out-of-spec confinement ring disrupts this assembly's geometric stack, leading to edge etch rate roll-off and increased wafer-edge defect density.

Endpoint Detection and APC Integration: Advanced Process Control (APC) systems on TPA175D platforms use optical emission spectroscopy (OES) and interferometry for endpoint detection. The confinement ring's optical transparency (in quartz configurations) and its influence on plasma emission uniformity directly affect OES signal quality. A system-matched 713-028553-102 ensures that endpoint detection algorithms receive consistent, repeatable emission profiles — a requirement for run-to-run process control and APC model accuracy.

Chamber Matching and Fleet Management: In multi-chamber and multi-tool fab environments, chamber matching protocols require that all consumable components — including the confinement ring, liner, focus ring, and upper electrode — be sourced to identical OEM specifications. The 713-028553-102, when used as part of a standardized PM (preventive maintenance) kit alongside the Lam Research chamber liner assembly, upper electrode, and ESC components, enables consistent chamber-to-chamber matching and reduces qualification cycle time after PM events.

Preventive Maintenance and Spare Parts Planning: The confinement ring is a scheduled PM consumable with a defined replacement interval based on RF-hours and process chemistry exposure. Integrating the 713-028553-102 into a structured spare parts inventory — alongside the focus ring, chamber liner, gas distribution plate, and quartz components — supports predictive maintenance strategies and minimizes unplanned downtime. NANKMOS maintains in-stock availability of the 713-028553-102 and associated TPA175D consumable families to support just-in-time PM scheduling.

Semiconductor Logic and Memory Manufacturing: In leading-edge logic fabs (7nm, 5nm, 3nm nodes) and DRAM/NAND memory production, the TPA175D TCP etch platform is deployed for dielectric etch, metal etch, and silicon etch applications. The 713-028553-102 confinement ring is a critical PM consumable in these environments, where process window margins are measured in angstroms and chamber-to-chamber matching is a continuous operational requirement. Its system-matched geometry ensures that etch uniformity specifications are maintained across the full wafer area, including the critical edge exclusion zone.

Advanced Packaging and 3D Integration: In advanced packaging fabs performing TSV (Through-Silicon Via) etching, RDL (Redistribution Layer) patterning, and wafer-level packaging processes, the TPA175D platform is used for high-aspect-ratio etch applications. The confinement ring's role in maintaining plasma confinement and process pressure uniformity is particularly critical in these applications, where etch depth uniformity and sidewall profile control are primary process metrics.

Compound Semiconductor and Power Device Manufacturing: GaN, SiC, and GaAs device fabs using TCP etch platforms for mesa isolation, gate recess, and via etching require confinement rings with high chemical resistance to halogen-based process chemistries (Cl₂, BCl₃, SF₆). The 713-028553-102, sourced to OEM material specifications, provides the required chemical durability for these aggressive process environments.

MEMS and Sensor Fabrication: MEMS fabs performing deep silicon etch (DRIE) and sacrificial layer removal on TPA175D-class platforms require precise plasma confinement to achieve the high aspect ratios and vertical sidewall profiles demanded by inertial sensor, pressure sensor, and RF MEMS device architectures. The confinement ring's dimensional stability over extended RF-hour intervals is a key reliability parameter in these applications.

Research and Pilot Line Environments: University research fabs, national laboratories, and semiconductor pilot lines operating TPA175D systems for process development and device prototyping require access to OEM-specification consumables to ensure that process development results are transferable to high-volume manufacturing. NANKMOS supports these environments with verified 713-028553-102 inventory and application engineering consultation.

Q1: Is the 713-028553-102 compatible with all TPA175D chamber configurations, and how does it interact with the focus ring and liner assembly during PM? The 713-028553-102 is designed specifically for the TPA175D-P10-L400-M-M750W chamber configuration. It is dimensionally matched to the standard TPA175D chamber liner and focus ring assembly. During PM, the confinement ring, focus ring, and chamber liner should be replaced as a coordinated set to maintain chamber geometry stack integrity. Replacing only the confinement ring without inspecting the focus ring and liner for wear can result in residual geometric mismatch that affects plasma uniformity even after PM. NANKMOS provides PM kit consultation to support coordinated consumable replacement planning.

Q2: How does the 713-028553-102 affect chamber-to-chamber matching in a multi-tool fleet, and what qualification steps are required after installation? In a multi-chamber fleet, the confinement ring is one of the primary variables in chamber matching protocols. After installing the 713-028553-102, standard qualification steps include RF impedance baseline verification, process pressure uniformity mapping, and a defined number of conditioning wafer runs to stabilize the chamber environment before production release. Using OEM-specification confinement rings across all chambers in a fleet — rather than mixing OEM and non-OEM parts — is the most reliable approach to minimizing chamber-to-chamber matching variance. NANKMOS supplies 713-028553-102 units with dimensional inspection records to support fleet qualification documentation.

Q3: What is the warranty coverage for the 713-028553-102, and what does NANKMOS's 12-Month Warranty include for this component?
