VARIAN E17031380 – Faraday Assembly for Ion Beam Current Measurement | R100U-15 Platform
Engineering Background
The Faraday assembly is a mission-critical beam diagnostics component in VARIAN ion implantation systems. Positioned within the beam line, it intercepts and measures ion beam current with high precision, providing real-time feedback to the implanter’s dose control system. Accurate Faraday measurement is essential for achieving repeatable, specification-compliant implant doses across wafer batches.
Product Positioning
Part number E17031380 is the primary OEM reference for this Faraday assembly, used across VARIAN’s R100U-15 and related ion implanter platforms. It is cross-referenced under multiple internal and service part numbers — E17010650, E17010570, E11001320, R100U-15, 0010-18042, and 414501 — ensuring compatibility across different service documentation revisions. This unit is sourced from verified OEM and certified aftermarket supply chains and is suitable for direct drop-in replacement in qualified maintenance windows.

System Architecture & Signal Flow
Within the VARIAN R100U-15 beam line, the Faraday assembly is positioned downstream of the analyzing magnet. Ions passing through the beam aperture are collected by the Faraday cup electrode, generating a measurable current signal. This signal is routed to the dose control electronics, which modulate scan parameters and beam exposure time to achieve the target implant dose. Degradation or contamination of the Faraday assembly directly impacts dose repeatability and can trigger dose alarms or process excursions.

Technical FAQ
Q: Are all six part numbers fully interchangeable?
A: Yes. E17031380, E17010650, E17010570, E11001320, R100U-15, 0010-18042, and 414501 are cross-references for the same assembly used across different VARIAN documentation revisions. Confirm your system serial number at inquiry for final verification.
Q: What is the typical replacement interval for this Faraday assembly?
A: Replacement frequency depends on beam current levels and process chemistry. Most fabs replace or inspect the Faraday assembly during scheduled quarterly or semi-annual PM cycles, or when dose alarms indicate measurement drift.
Q: Can you provide a Certificate of Conformance?
A: Yes. CoC documentation is available for all units. Please request at time of order placement.
Q: Do you support urgent / emergency orders?
A: Yes. Contact us directly via phone or email for expedited processing. We prioritize unplanned downtime situations.
Q: What are the export restrictions for this part?
A: This component may be subject to U.S. Export Administration Regulations (EAR). Konmask conducts export compliance review on all international orders. End-user documentation may be required.
