Used Axcelis GSD Ion Implanter: Buyer Checklist
Evaluate a used Axcelis GSD ion implanter: verify configuration, process fit, acceptance evidence, deinstallation scope and quote exclusions.
Use this checklist to define the evidence you require before approving a purchase. Start with the exact unit identity, not a similar model name.
What to match before requesting a quote
- Exact model suffix, serial number and installed options. Request documentary evidence and compare it with your purchase requirements.
- Your wafer, species, energy and dose requirements against serial-specific documentation. Request documentary evidence and compare it with your purchase requirements.
- Utilities, service access and deinstallation scope. Request documentary evidence and compare it with your purchase requirements.
Acceptance evidence to request
Have your process engineer define the acceptance recipe and pass/fail limits before inspection. Request witnessed results for the agreed process, calibration records, maintenance history and a list of unresolved alarms.
Tie the report to the offered serial number or label photo. Record any untested functions and agree who will resolve each exception before payment. Use manufacturer limits and your application requirements for the pass/fail criteria.
Process fit and installation scope
Ask for documented evidence for your intended substrate, wafer size, implant species, energy, dose and temperature requirements. Do not approve a SiC application or a model upgrade solely from a family name. Have the process owner sign off on the serial-specific configuration and acceptance results.
Request an itemized plan for decontamination, deinstallation, rigging, packing, transport, installation and commissioning. Identify the responsible party and exclusions for each stage. Ask for the applicable manuals and service-support proposal before agreeing the scope.
What should the written quote include?
Request the exact part or model identifier, condition, included accessories, test scope, seller location and itemized freight. Ask the seller to confirm current availability, dispatch timing, warranty and return terms in writing. For a repair or replacement purchase, include photos of your existing unit and the configuration you need to match.
