50020R-10 810-002895-232 0041-81423 C2088 HC-SFS202 Product Description

The Lam Research 810-002895-232 Node Rocker Valve is a precision gas-path control component engineered for deployment within the Kiyo series capacitively coupled plasma (CCP) etch platform. Carrying cross-reference identifiers 0041-81423, C2088, and HC-SFS202 under internal part number 50020R-10, this valve module occupies a critical position in the process gas delivery and chamber isolation architecture. Its role extends beyond simple on/off switching: it governs the sequencing of reactive gas flows, chamber conditioning cycles, and inter-step purge events that define etch uniformity, process repeatability, and equipment uptime across high-volume semiconductor manufacturing environments.

In the context of the Kiyo etch system's layered control hierarchy, the 810-002895-232 operates at the intersection of the gas delivery subsystem and the chamber process control layer. It interfaces directly with the system's mass flow controller (MFC) manifold network, responding to valve actuation commands issued by the chamber controller or process module controller (PMC). Its fast-response rocker mechanism enables precise timing of gas introduction and exhaust sequencing, which is essential for achieving the etch profile consistency demanded by advanced logic and memory device fabrication nodes.

The 810-002895-232 Node Rocker Valve does not function in isolation — it is one node in a tightly coordinated gas delivery and process control network. Understanding its system context is essential for procurement engineers, process integration teams, and spare parts planners responsible for maintaining Kiyo platform uptime.

At the control layer, the Kiyo Process Module Controller (PMC) issues sequenced valve actuation commands based on recipe-defined step parameters. The PMC coordinates with the Chamber Controller (CC) to synchronize gas introduction timing with RF power delivery events, ensuring that plasma ignition occurs only when the correct gas mixture and pressure conditions are established. The 810-002895-232 is one of several node valves in the gas panel that must respond within defined timing windows to maintain process integrity.

At the I/O layer, digital output modules within the Kiyo's I/O chassis provide the 24 VDC actuation signals to the solenoid-driven rocker mechanism. Companion components such as the Lam Research 810-002895-231 (adjacent node valve in the same manifold assembly) and the 810-002895-233 (downstream isolation valve) work in concert with the 232 variant to define the complete gas path switching sequence. Valve status feedback is returned to the I/O module via discrete digital input channels, enabling the PMC to confirm valve position before advancing to the next recipe step.

At the gas delivery and MFC layer, the node rocker valve interfaces with the upstream mass flow controller (MFC) manifold — typically Lam Research-qualified MFC units calibrated for specific process gases. The valve's open/close state determines whether gas flow from a given MFC channel reaches the chamber inlet or is diverted to the exhaust/foreline path. Proper valve sequencing prevents cross-contamination between process steps and protects the chamber from unintended gas mixing events.

At the power and pneumatic layer, the valve's pneumatic actuator is supplied by the system's clean dry air (CDA) distribution network. The Lam Research pneumatic solenoid driver assembly (part of the gas panel sub-assembly) governs CDA pressure delivery to the actuator. Failures in the CDA supply or solenoid driver will manifest as valve position faults, which the PMC will flag as process interlock conditions — halting the recipe and triggering a maintenance alert.

At the communication and diagnostics layer, the Kiyo platform's Equipment Engineering Controller (EEC) aggregates valve status data alongside MFC flow readings, chamber pressure (from the MKS Baratron capacitance manometer or equivalent), and RF match network parameters. This data stream feeds into the fab's Equipment Data Acquisition (EDA/SECS-GEM) interface, enabling real-time process monitoring and fault classification. A valve that fails to reach its commanded position within the defined timeout window will generate a SECS event that the fab's manufacturing execution system (MES) can log and trend for predictive maintenance purposes.

At the maintenance and spare parts layer, the 810-002895-232 is a scheduled preventive maintenance (PM) item. Kiyo platform PM kits typically include node rocker valves alongside O-ring kits, chamber liner assemblies, focus ring sets, and edge ring components. Maintaining a buffer stock of the 810-002895-232 — along with its cross-reference equivalents 0041-81423 and HC-SFS202 — is standard practice for fabs running Kiyo tools at high utilization rates, where unplanned valve failures can result in significant wafer loss and tool downtime costs.

The Lam Research 810-002895-232 Node Rocker Valve is deployed across a range of semiconductor manufacturing and advanced process control environments where gas-path precision and system reliability are non-negotiable.

Logic Device Fabrication (Front-End-of-Line Etch): In high-volume logic fabs producing advanced node devices (7nm, 5nm, 3nm), the Kiyo platform is used for critical dielectric and conductor etch steps. The 810-002895-232 governs gas switching between etch chemistry (e.g., CF₄/CHF₃/Ar) and purge gas (N₂) during multi-step etch sequences. Valve response time and leak integrity directly impact etch selectivity and critical dimension (CD) control.

DRAM and NAND Flash Memory Manufacturing: Memory fabs operating Kiyo tools for wordline and bitline etch applications rely on precise gas sequencing to achieve the high aspect ratio structures required by advanced 3D NAND architectures. The node rocker valve's role in isolating individual gas channels prevents cross-contamination that could degrade device yield.

Compound Semiconductor and Power Device Processing: Kiyo platforms adapted for GaN, SiC, and III-V compound semiconductor etch applications require valve components rated for aggressive chemistries. The 810-002895-232's material compatibility with halogen-based process gases makes it suitable for these specialized etch environments.
