LAM 673-092355-006

Product Introduction

The LAM 673-092355-006 is a critical ultra-high vacuum (UHV) RF feedthrough engineered by LAM Research—an industry leader in semiconductor manufacturing equipment—specifically to bridge the RF matching network and plasma chamber in advanced etch and deposition systems. As a low-loss, UHV-sealed transmission component, it addresses the semiconductor industry’s core challenge of balancing RF power efficiency and vacuum integrity: plasma processes require both minimal RF power loss (to maintain stable plasma) and UHV sealing (to prevent gas contamination), and even minor flaws in either area can ruin 300mm wafers or damage chamber components.

In semiconductor fabs, the LAM 673-092355-006 acts as a “plasma power bridge” for LAM’s 9000 Series etch systems and 2300 Series deposition systems. It transmits RF power (up to 3000 W at 13.56 MHz) from the matching network (e.g., LAM 685-094680-001) to the plasma chamber while maintaining ≤1×10⁻⁸ Torr vacuum. For example, in a LAM 9000 tool processing 5nm logic chips, the LAM 673-092355-006 ensures <0.1 dB RF insertion loss—meaning 97.7% of the 2000 W forward power reaches the plasma, avoiding power waste and plasma instability. Today, it remains an essential component in leading fabs worldwide, where RF-vacuum synergy directly impacts wafer yield and the reliability of next-generation semiconductor processes.

Core Advantages and Technical Highlights

UHV Sealing for Contamination-Free Plasma Processes: The LAM 673-092355-006’s electropolished 316L stainless steel CF flange and 99.8% purity alumina insulator achieve ≤1×10⁻⁸ Torr vacuum and ≤1×10⁻¹³ Torr·L/s outgassing—10x better than standard RF feedthroughs. In a Taiwanese fab using LAM 9000 etch systems, the LAM 673-092355-006 reduced vacuum-related defects (e.g., particle contamination from outgassing) by 28% compared to third-party feedthroughs (which had 1×10⁻⁷ Torr outgassing). This improvement translated to a 3.2% increase in wafer yield—worth $3.5M annually for a fab producing 100,000 300mm wafers per month.

Ultra-Low RF Loss for Power Efficiency: With ≤0.1 dB insertion loss and ≤1.05:1 VSWR at 13.56 MHz, the LAM 673-092355-006 minimizes RF power waste—critical for high-power etch steps (e.g., deep silicon etching) where energy efficiency directly impacts operational costs. A U.S. fab testing the feedthrough in a LAM 9000 system for 50 μm deep silicon etching found it preserved 98% of the 2500 W RF power—vs. 92% preservation with generic feedthroughs. This efficiency reduced RF generator energy consumption by 8%, translating to $144,000 in annual electricity savings for a 20-tool fab.

High-Temperature and Chemical Resistance for Longevity: The LAM 673-092355-006’s alumina insulator (99.8% purity) withstands plasma chamber temperatures up to 80°C and resists corrosion from fluorinated etch gases (e.g., NF₃, CF₄) and O₂ plasma cleaning. A European fab using the feedthrough in a LAM Coronus® clean system found it maintained performance for 60,000+ plasma cycles—vs. 30,000 cycles for feedthroughs with lower-purity alumina (95%). This longevity cut feedthrough replacement frequency by 50%, reducing maintenance costs and fab downtime.

Seamless Integration with LAM RF Ecosystem: Unlike generic feedthroughs that require custom flange adaptation, the LAM 673-092355-006’s 4.5” CF flange directly mates with LAM 9000/2300 Series chamber flanges and RF matching network outputs. It also pairs natively with the LAM 685-094680-001 (RF matching capacitor) and LAM 678-009953-001 (RF coupler) for closed-loop RF control. A Korean fab reported that integrating the three components reduced RF system setup time by 60% (from 5 hours to 2 hours) compared to mixed-brand setups, freeing technicians for critical tasks like tool calibration.

Typical Application Scenarios

LAM 9000 Series Etch for 5nm Logic Chips

A leading semiconductor fab in South Korea uses LAM 673-092355-006 feedthroughs in 28 LAM 9000 etch systems processing 5nm logic chips for high-performance computing (HPC) applications. Each feedthrough:

Transmits 1800 W of 13.56 MHz RF power from the LAM 685-094680-001 matching capacitor to the plasma chamber, with <0.1 dB insertion loss and ≤1.05:1 VSWR—ensuring stable plasma for etching 5nm transistor gates.

Maintains ≤1×10⁻⁸ Torr vacuum during 12-hour production runs, preventing gas contamination that would cause “etch stop” defects.

Its RF shield grounding (≤50 mΩ resistance) eliminates electromagnetic interference (EMI) with nearby LAM 515-011835-001 MFCs, ensuring precise gas flow regulation.

Over 6 months, the fab reported zero RF-vacuum related tool failures, and etch process yield increased by 4.5%—equivalent to $4.9M in additional revenue from 300mm wafers. The feedthrough’s durability also reduced maintenance time by 40% (from 10 hours/month to 6 hours/month).

LAM 2300 Series Deposition for 3D NAND Memory

A U.S. fab uses LAM 673-092355-006 feedthroughs in LAM 2300 deposition systems for atomic layer deposition (ALD) of tungsten (W) films in 3D NAND memory chips. The feedthrough:

Delivers 1200 W of 13.56 MHz RF power to ionize WF₆ precursor gas, with ultra-low loss ensuring consistent plasma density for uniform W film growth.

Its UHV sealing (≤1×10⁻⁸ Torr) prevents ambient air from entering the chamber, avoiding tungsten oxide formation that degrades film conductivity.

This setup maintained film resistivity within 1.5% of the target (5.5 μΩ·cm) across 10,000 wafers—exceeding the fab’s requirement of ±2%—and reduced ALD-related defects by 32%, meeting the strict yield standards for 3D NAND production.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing LAM 673-092355-006, verify compatibility with the target LAM system (e.g., 9000 Series etch) via LAM’s part cross-reference tool. Work in an ISO Class 2 cleanroom (use cleanroom gloves/coveralls) to avoid particle contamination of the flange and insulator. Gather tools: calibrated torque wrench (25 N·m range), titanium flange bolts (included with the feedthrough), new copper gasket (LAM 673-092355-GSKT), helium leak detector (sensitivity ≤1×10⁻¹¹ Torr·L/s), and anti-static wristband. Ensure the plasma chamber is vented to atmospheric pressure and RF power is disconnected (15 kV risk). Align the feedthrough’s CF flange with the chamber flange—misalignment >0.5 mm causes vacuum leaks; clean flange surfaces with isopropyl alcohol (IPA) and a lint-free cloth before installation.

Maintenance suggestions: Monthly, perform a helium leak test on LAM 673-092355-006—if leak rate exceeds 1×10⁻¹⁰ Torr·L/s, replace the copper gasket. Every 6 months, inspect the RF connector for corrosion or damage—clean silver-plated contacts with IPA (avoid abrasive materials) and torque to 18 N·m if loose. Annually, test RF insertion loss and VSWR using a network analyzer—if insertion loss >0.15 dB or VSWR >1.1:1, schedule service to clean the conductive core. For emergency repairs, keep a spare LAM 673-092355-006 on hand—fab downtime for feedthrough replacement can cost $60,000+ per hour. Never expose the feedthrough to cleaning solvents (e.g., acetone), as they damage the alumina insulator.
