LAM 685-069171-100 | HORIBA Spectrometer Assembly

Description

• Model: 685-069171-100
• Brand: LAM Research
• Series: LAM Semiconductor Equipment / HORIBA Spectrometer
• Core Function: Optical spectroscopy for process monitoring
• Type: Spectrometer / Spectrometer Control Assembly
• Key Specs: HORIBA OEM unit; assembly revision B reported; OEM reference S9840/1010161

Available equipment-spare listings consistently identify 685-069171-100 as a LAM Research HORIBA spectrometer, with one listing specifying REV.B, 1010161 / OEM S9840.

Product Introduction

LAM Research 685-069171-100 is identified in the secondary semiconductor-equipment market as a HORIBA spectrometer assembly used within LAM processing equipment. It is a specialized optical measurement spare rather than a general-purpose PLC or industrial automation module.

The available references identify the unit as REV.B and associate it with HORIBA OEM S9840 / 1010161. Exact wavelength range, detector configuration, interface specification, and host-tool compatibility are not sufficiently documented in the sources reviewed, so those details should be confirmed from the equipment serial number and original LAM/HORIBA documentation before purchase.

Key Technical Specifications

Important: Publicly available listings do not provide a sufficiently reliable datasheet for the detailed optical specifications. Do not assign a wavelength range, spectral resolution, detector type, communication protocol, or operating-temperature limit without confirming the exact unit documentation.

Installation & Configuration Guide

Stage 1 — Pre-Installation

Estimated time: 10 minutes

⚠️ Follow the semiconductor tool manufacturer’s maintenance procedure before accessing the module.

1. Place the process tool in the approved maintenance state.
2. Follow the equipment-specific power and energy-isolation procedure.
3. Wear the required ESD protection.
4. Record the existing spectrometer’s part number and revision.
5. Photograph all optical, electrical, and communication connections.
6. Record the host-tool model and chamber/process position.
7. Compare the replacement label with the original unit.

For this part, the host tool and exact revision matter. A visually similar spectrometer should not be treated as interchangeable without confirmation.

Stage 2 — Remove Existing Assembly

Estimated time: 10 minutes

1. Verify the equipment is in the approved maintenance condition.
2. Identify each cable and connector.
3. Photograph connector orientation before removal.
4. Disconnect cables using the connector hardware rather than pulling on the wiring.
5. Release the assembly from its mounting bracket.
6. Remove the unit carefully and protect optical interfaces from contamination.
7. Inspect connectors and mounting points.

Stage 3 — Install 685-069171-100

Estimated time: 10 minutes

1. Verify the complete part number and revision.
2. Inspect the optical and electrical interfaces.
3. Install the spectrometer in the original mounting location.
4. Reconnect all cables according to the recorded configuration.
5. Confirm that no optical surface or connector has been contaminated.
6. Verify mechanical alignment before restoring the system.

Do not improvise optical alignment. Follow the specific LAM/HORIBA tool procedure.

Stage 4 — Functional Verification

Estimated time: 15–30 minutes

1. Restore system power following the OEM procedure.
2. Confirm the spectrometer is detected by the host system.
3. Check diagnostic/status information.
4. Perform the tool’s built-in spectrometer initialization or calibration routine, where applicable.
5. Verify that measurement data is being received.
6. Compare baseline readings with historical process data.
7. Run an approved verification wafer or qualification procedure before returning to production.

Common Replacement Risks

1. Wrong HORIBA Revision

REV.B is reported for this part number, but different revisions may exist in the field.

Check: Match the revision printed on the installed unit before ordering.

2. Host-Tool Mismatch

This is a tool-specific semiconductor equipment component, not a universal spectrometer.

Check: Confirm the LAM tool model, subsystem location, and installed software configuration.

3. Optical Contamination

Dust or residue on optical interfaces can affect measurement quality.

Check: Maintain cleanroom handling practices and follow the equipment-specific optical cleaning procedure.

4. Calibration Data

A replacement spectrometer may require calibration or qualification even when the hardware revision matches.

Check: Preserve the original calibration/configuration records before removal.

5. Used-Part Condition

Several current market listings classify this part as pre-owned or refurbished, rather than new factory stock.

For procurement, request actual photos, serial number, revision marking, test status, and warranty terms.

FAQ

1. What is LAM 685-069171-100?

It is identified by multiple equipment-spare sources as a LAM Research HORIBA spectrometer.

2. Is this a PLC or DCS module?

No. It is an optical spectroscopy assembly associated with semiconductor process equipment, not a standard PLC/DCS I/O or control module.

3. What HORIBA model is associated with this part?

Available listings associate the part with HORIBA OEM S9840 / 1010161, and one source specifically reports REV.B.

4. Can any 685-069171-100 be installed directly?

Not necessarily. Confirm revision, host equipment, connector configuration, and software/calibration requirements before replacement.

5. Is this part available new?

The sources reviewed primarily show pre-owned, used, or refurbished units. One listing reports a used unit with a 3-month warranty, while another offers a nearly new unit with a 12-month warranty. Actual condition must be confirmed with the seller.

6. What information should be provided when requesting a quotation?

Provide 685-069171-100, the revision marking, serial number, host LAM tool model, required condition, and desired warranty. That is much safer than quoting the part number alone.

7. What should be kept as a spare?

For a production-critical spectrometer, one tested spare matched to the exact tool configuration is more useful than an unverified visually similar unit. Before stocking, record the spectrometer revision and calibration/qualification status.
