Lam Research 810-099175-012
Product Name
Public spare-part sources list this number under different identities. Verify the physical assembly before use.
Option A – Signal Conditioning / Temperature Conditioning Module
Product Type: Analog signal conditioning and temperature acquisition module.
Detailed content
MCU: 32-bit microcontroller according to listing.
ADC: 24-bit sigma-delta according to listing.
Input Types: Thermocouple, RTD, and standard analog signals according to listing.
Front-End: Programmable gain amplifiers, cold-junction compensation, surge and overvoltage protection.
Accuracy: Better than ±0.1°C system-level according to listing.
Communication: Isolated RS-485 or DeviceNet according to listing.
Output: Opto-isolated PWM drive and communication interface.
Diagnostics: Open-circuit, short-circuit, and over-range detection.
EMI Design: Differential inputs, separate analog ground, common-mode filtering.
Platforms: Listed sources associate it with Lam 2300 Kiyo, Flex, and Versys thermal control subsystems.
Option B – Edge Ring / Wafer Guard Ring
Product Type: Silicon edge ring or wafer guard ring.
Application: 300 mm ESC and etch chamber edge protection.
Function: Reduces wafer-edge plasma exposure, controls bevel effect, and improves edge uniformity.
Option C – Power / Process Controller Listing
Some sources list 099175-012 as IGBT-based power controller with 600–1200 VDC input, high-current output, Modbus/EtherCAT/CAN communication, and temperature/pressure/flow control functions. These specifications conflict with the conditioning-module and edge-ring identities and require BOM confirmation.
Working Principle
Conditioning version amplifies weak sensor signals, converts them through ADC, processes temperature algorithms, and transmits calibrated data to host controller. Edge-ring version modifies plasma electric field at wafer periphery. Power-controller version regulates high-voltage/current output for process equipment.
Application Scenarios
Conditioning: ESC zone temperature control, chamber wall thermal monitoring, gas-line heater control, PECVD substrate heating, and MBE temperature stabilization according to listed source. Edge ring: 300 mm etch chambers. Power controller: high-voltage conversion and industrial power managements according to conflicting source.
Installation Requirements
Conditioning: install in designated thermal-control slot, set channel types in software, connect sensor inputs with proper cold-junction reference, verify communication address. Edge ring: install concentrically on ESC, clean before use. Power controller: mount with rated isolation, verify input voltage class, and apply ESD/lockout procedures.
Usage Precautions
Conditioning: calibrate temperature channels periodically, protect thermocouple inputs from RF noise, verify isolation before energizing. Edge ring: inspect for cracks and plasma erosion. Power controller: do not exceed voltage/current rating, use overcurrent and overtemperature protection.
Source Note
Because 810-099175-012 is listed as conditioning module, edge ring, and IGBT controller in different sources, determine the correct identity from part label, chamber platform, and Lam BOM before procurement or service.
