LAM 605-109114-003 Semiconductor Analog Control Board

Product Description

The 605-109114-003 is an analog control PCB board for LAM Research semiconductor etching process equipment. It is the upgraded revision of 605-109114-002, responsible for analog signal sampling, setpoint output and closed-loop control of gas flow, pressure and RF power inside the plasma etcher chamber. It communicates with the main system controller to stabilize process parameters during wafer etching, and is a critical spare part for LAM etch tools.

FAQ

Q: What is the difference between 605-109114-002 and 605-109114-003?
A: 605-109114-003 is the newer hardware revision with optimized circuit and improved stability for long etching cycles.

Q: What equipment does this board fit?
A: It is designed for LAM series plasma etch process tools used in wafer fabrication.

Q: Is this board discontinued?
A: This is legacy semiconductor tool hardware, original production stopped, supplied as surplus, refurbished and tested spare parts only.

Q: Can it work independently without the etcher main controller?
A: No, it must be installed in the LAM tool rack and work with the host controller and process software.
