A practical comparison of new, refurbished and second-source semiconductor parts across condition grade, warranty, price delta, lead time and traceability, with a decision view for legacy 200mm fabs.
Securing the supply chain for legacy 200mm fab parts comes down to five levers: scoring part-level risk, tiering suppliers, sizing buffer stock against lead-time variance, qualifying a second source, and reading the geopolitical layer.
How to read LAM Research and Tokyo Electron OEM part numbers — decoding the prefix, base number and revision suffix, then cross-referencing and tracing supersession to source qualified second-source equivalents.
A step-by-step guide to qualifying a second-source part for production in a 200mm fab: controlled specification, incoming inspection, copy-exact, the marathon run, acceptance criteria and the documentation pack.
A structured method for sourcing semiconductor spare parts across OEM, qualified second-source and surplus tiers — covering qualification, OEM cross-referencing, lead-time benchmarks, pricing and a supply-risk scoring model for legacy 200mm fabs.
200mm fab demand is heading for record highs in 2026, driven by power, analogue, MEMS and MCU devices. Here is why these fabs still matter — and the obsolescence risk hidden inside that demand.
200mm tools designed for ten years often run past twenty. Here is how to extend their service life through lifecycle staging, refurbishment, a spares strategy and targeted upgrades.
When an OEM discontinues a fab part, should you stockpile it or qualify a second source? A practical guide to LTB quantity, carrying cost, shelf-life and the decision logic for 200mm and legacy tools.
When an OEM issues an end-of-life or PDN notice for a legacy fab tool, the last-order and last-ship dates govern your response. Here is the action checklist, the JESD48 last-time-buy window, and when to pivot to a qualified second source.
A step-by-step guide to building an obsolescence management plan for a legacy 200mm fab, aligned to IEC 62402, with a risk-register template, monitoring cadence, budget model and governance roles for LAM, TEL and AMAT toolsets.
