The LAM Analogue I/O (AIO) Board, OEM part number 810-017031-002, is a printed circuit board assembly used within LAM Research plasma etch and deposition platforms to bridge the system controller and the analogue domain of the tool. The designation “AIO” refers to analogue input/output: the board conditions, digitises and outputs the continuous voltage and current signals that the process controller relies on to read sensors and command actuators. In semiconductor process equipment, where chamber conditions are governed by fractional changes in flow, pressure and power, the integrity of these analogue channels is fundamental to repeatable wafer results.
Physically, the AIO board sits in the tool’s control card cage or a distributed I/O chassis, typically engaging a backplane connector or harness that carries power, digital bus communication and field wiring to and from the chamber subsystems. From this position it interfaces with mass flow controllers, capacitance manometers, throttle valve position feedback, temperature sensors and the RF and bias supplies, translating real-world physical quantities into the digital values the host software interprets.
Because the AIO board governs the accuracy of the signals that close every process loop, a degraded or failed unit rarely produces a clean fault. Instead it manifests as drift, noise and intermittent process excursions that are difficult to diagnose, which is why holding a verified replacement on the shelf protects both uptime and yield.
The AIO board is the analogue gateway of the control architecture. It carries the analogue-to-digital and digital-to-analogue conversion stages, the input signal conditioning and the output drive circuitry that allow the digital controller to sense and steer the process environment. Its principal functions include:
As a mixed-signal assembly, the AIO board must preserve measurement precision in an electrically hostile environment. Its performance is judged less on raw speed than on the fidelity, stability and isolation of its analogue paths.
The board’s usefulness depends on the linearity, resolution and long-term stability of its converters and reference. Small offset, gain or temperature-related errors translate directly into misread process variables and mis-set commands.
Plasma tools generate substantial RF and switching noise. The board relies on filtering, isolation and protection circuitry to keep that interference out of low-level measurement channels.
Because the AIO board sits inside every analogue control loop, its condition shapes the outcome of every wafer the chamber processes. When the board performs to specification it is invisible; when it degrades, the effects propagate through the process:
Over years of thermal cycling, the voltage reference, precision resistors and amplifiers age, introducing offset and gain errors. The board may still function but report values that no longer match calibration, producing slow, hard-to-spot process drift.
Repeated insertion, vibration and thermal expansion fatigue backplane contacts and surface-mount solder joints. The result is intermittent channels, noisy readings or signals that drop out when the board or cabinet is disturbed.
Voltage transients, miswiring during maintenance and RF coupling can damage input protection, isolation devices or converter front ends. This can leave a single channel dead or pinned while the rest of the board appears healthy, complicating diagnosis.
The AIO board should be replaced only by qualified personnel following LAM-approved lock-out and ESD procedures. Sensitive analogue assemblies demand careful handling and a full verification cycle before the chamber returns to production. A typical sequence is:
Control boards such as the AIO assembly are low-cost relative to the value of the wafers a tool runs each hour, yet a missing spare can idle a chamber for days. Sourcing through ESCT Fab Support gives fabs a pragmatic alternative to long OEM channels:
It is the analogue input/output interface between the digital system controller and the tool’s sensors and actuators. It digitises sensor signals such as pressure and flow and outputs the analogue commands that set valves, flows and power references, closing the loops that control the process.
No. This board is supplied as an OEM-compatible replacement cross-referenced to OEM P/N 810-017031-002. It is not an original LAM Research part and is not supplied by the OEM, but it is verified to match the original in form, fit and function.
Match the OEM part number on your installed board to 810-017031-002 and quote ESCT P/N ES2022-087 when ordering. Our team can help confirm applicability against your tool model and control configuration before you purchase.
The standard lead time is three weeks. We recommend holding at least one unit as on-site spare stock so a failure can be addressed immediately rather than waiting on resupply.
Yes. Because the board carries analogue measurement and command channels, you should run the tool’s analogue calibration routine and a process verification after fitting it, checking readings and outputs match the expected references before returning to production.
Watch for drifting or noisy sensor readings, setpoints that no longer track commands, intermittent channel dropouts when the cabinet is disturbed, and unexplained process variation between wafers or chambers. These point to converter drift, connector wear or front-end damage on the analogue board.
The LAM Analogue I/O Board (OEM P/N 810-017031-002, ESCT P/N ES2022-087) is the analogue interface that lets a LAM Research plasma processing system measure and control its chamber environment. By digitising sensor signals and driving analogue commands with precision and isolation, it underpins process accuracy, repeatability and yield. As an OEM-compatible replacement verified to form, fit and function, with a three-week lead time and technical support, it offers fabs a dependable, cost-effective way to keep critical control hardware on the shelf and tools running.
