Supplying Arizona's Chip Industry Takes Traceable Records, Not a New ERP

Small and mid-size Arizona manufacturers selling into the chip industry are usually asked for three records: lot traceability back to the raw material, a certificate of conformance with each shipment, and approval before changing a material, process or subcontractor. None of that requires a new ERP. It requires records that exist, stay under control and can be found fast.

What the Arizona fab build-out means for local suppliers

Since 2020, Arizona has attracted more than 70 semiconductor expansions, representing over $314 billion in investment, according to the Arizona Commerce Authority figures in the City of Phoenix's July 2026 announcement of TSMC's latest expansion. That expansion brings Taiwan Semiconductor Manufacturing Company's (TSMC) total Arizona investment to $265 billion, ENR reported, for 10 fabs, two advanced packaging facilities and a research and development center.

The Greater Phoenix Economic Council's April 2025 report, citing Semiconductor Industry Association data, says the region's semiconductor value chain has drawn more than $100 billion in investment since 2020, and counts more than 33,000 semiconductor industry jobs. The report also notes that suppliers, service and equipment providers far outnumber the fabs, and that GPEC has helped nearly 40 of those companies move to Greater Phoenix since 2021. For a local machine shop, plater or fabricator, those newcomers are potential customers and potential competitors.

Why the requirements reach small suppliers

For many small shops, the customer is not the fab itself but a toolmaker, subsystem builder or contractor that serves it, and that customer passes the fab's expectations down through its own purchase orders and quality manual. The published quality guidelines of Semsysco, an equipment maker owned by Lam Research, are a fair example: they make a zero-defect strategy mandatory and require suppliers to hold their own subcontractors to the same rules. Many small suppliers still keep their records on paper travelers and spreadsheets. That can work, as long as the records exist and can be produced on demand.

Chipmakers have reason to push. A SEMI and McKinsey supply chain analysis, reported by Semiconductor Engineering in May 2024, found that 80% of supply chain disruptions occur at the Tier 2 and Tier 3 levels, counting the chipmakers themselves as Tier 1; visibility gets poorer the further a supplier sits from the chipmaker. When something does go wrong, the clock is short: if Semsysco asks a supplier for an 8D corrective-action report, its guidelines want the immediate measures reported within one working day and an updated report setting out the long-term corrective actions within ten working days. A supplier it rates C is blocked for new orders.

The three records customers ask for

Requirements differ by customer and are set in each purchase order and quality agreement, but three records come up again and again:

• Lot traceability: the ability to trace a finished part back to its raw material heat or batch, the subcontracted steps it went through, such as plating, heat treatment or cleaning, and its inspection results, and to trace forward from one heat to every shipment that used it.
• Certificates of conformance (CoC): a signed statement with each shipment that the parts meet the drawing and the purchase order, often backed by mill certificates, subcontractor certificates and inspection reports. Semsysco's guidelines list what an inspection report must contain for the dimensions they flag on a drawing, down to the gauge used and the measured values, and expect those reports to ship with the parts without being asked.
• Change notification: written notice, and customer approval, before you change a material, process, piece of equipment or subcontractor. Intel's supplier quality page describes a tool its suppliers use to submit change forecasts for the materials, equipment and services they provide, and Semsysco's guidelines state that product or process changes are subject to approval.

One of Nutron's founders has seen what a skipped change notice costs. At Tier 2 or Tier 3, where supply chain visibility is lowest, a supplier quietly alters a process, such as switching cleaning vendors, swapping a heat of raw material or modifying a plating step. The customer, a toolmaker or the fab itself, first notices when nonconforming parts cause defects or integration failures downstream in assembly. It immediately demands an 8D corrective-action report. The supplier's quality rating is downgraded, which automatically blocks new purchase orders. To lift the block and keep the account, the supplier must put a controlled system behind each record above, including a change process that stops the job until the customer approves in writing.

One boundary. If you also make parts under Defense Department contracts, the cybersecurity rules for controlled unclassified information are a separate obligation, and they come from the contract, not from the customer's industry. DFARS clause 252.204-7012 requires NIST SP 800-171 for covered defense information and must be passed down to subcontracts that involve it. If a purchase order carries that clause, get specialist advice; it is outside the scope of this article.

You probably do not need a new ERP or an MES

The requirements quoted above describe what a record must show and how fast you must produce it, not which software keeps it. Before buying anything, check what you already own. ECI's JobBOSS², a job-shop ERP sold to small and mid-size manufacturers, lists supplier lot traceability, calibration tracking and quality workflows among its features. A shop that turns on features it already pays for may need nothing custom at all.

The best case for buying comes from the companies that sell manufacturing execution systems (MES), and it deserves a fair hearing. Siemens, writing in February 2026, cites a Gartner report, Build, Buy or Go Hybrid With Manufacturing Execution Systems, which found that packaged software tends to cover only 70% to 90% of a manufacturer's needs. Siemens' answer is to buy a strong core system and extend it where the plant is different, and for a large plant that is a sound position. For a small supplier the same finding cuts the other way: the part of the job that is specific to your shop needs custom work whichever route you take, so start from the system you already run.

Do not attempt to automate process change notifications or lot traceability if your baseline machine data relies on hand-written paper travelers with unvalidated measurements. Clean up data capture at the station level first. Automating an unvalidated paper process only produces bad records faster.

Replacing the ERP is the right call in one situation: the current system is out of support or cannot hold lot and certificate data at all. Otherwise, keep the accounting and scheduling software that works, and add small tools only where records still fall through the gaps.

Four ways to keep the records

The table compares the options a small supplier actually has, from the cheapest to the most disruptive.

Where a small tool earns its place

The useful automation in a small shop is narrow. It removes the retyping between the place a record is created and the place it has to end up.

Measurements from a coordinate measuring machine (CMM) or a digital gauge can go straight into the inspection record instead of being copied from a printout. A mill test report can be read for its heat number and matched to the purchase order, with a person confirming any mismatch before the material is released to the floor. A certificate package can be assembled from records that already exist rather than rebuilt by hand for every shipment.

If retyping is where your records break down, Nutron's manufacturing operations work connects the systems a plant already runs instead of replacing them, and anywhere in the Phoenix metro we will meet you at your site or ours.

A checklist before you quote chip-industry work

Answer these with the records in front of you. A no is not a reason to buy software. It tells you which record to fix first.

1. Material and lot traceability

• Pick a part you shipped last quarter. Could you produce its material certificate, heat number and inspection record the same day a customer asks?
• Going the other way, could you list every shipment that used material from one heat?
• Are subcontracted steps such as plating, heat treatment and cleaning recorded against the lot, with the subcontractor's certificate attached?

2. Change control

• Is there one written list of what you may not change without telling the customer: material, process, equipment, subcontractor or location?
• Does someone own that list, and does a change request stop the job until the customer approves it?
• When a work instruction is revised, is the old version pulled from the floor?

3. Certificates and inspection records

• Does each certificate of conformance tie to actual inspection results, or is it a signature on a template?
• Do your inspection reports show the part and serial number, quantity checked, gauge used, tolerance, measured value, date and inspector?
• Is every gauge on those reports within its calibration date?
• Do you keep these records as long as each customer requires? Semsysco's guidelines, for one, ask for at least ten years.

Where to start

Our position: a small Arizona supplier does not need a new ERP or an MES to meet the chip industry's record requirements. It needs the three records, kept under control and easy to find, and most of that is discipline before it is software. Fix data capture at the station, use what your current system already does, and add small tools only where records still fall through the gaps. Your customers decide whether you qualify; good records make that decision easier. If the gap is the quality system itself, Arizona MEP, the state's manufacturing extension partnership, lists quality management and ISO and AS certifications among its services for Arizona manufacturers.

If you want an outside view before spending money on software, Nutron's operations audit is a two-week paid diagnostic, from $1,500. We map how records and work actually move through your shop, put an annual cost on each bottleneck, and hand you a prioritized roadmap that any competent team can carry out, ours or someone else's. It is not a certification or a compliance review.
