Semiconductor Equipment Shipping Inspection: What to Check the Moment It Arrives

This guide is for: anyone who just received a pallet of used semiconductor equipment and is standing in the receiving dock wondering if the carrier bent something important.

The moment that truck pulls away, your legal position changes. Damage claims have time windows — typically 5 to 15 days from delivery for concealed damage, and "I didn't check immediately" is not a defense the carrier will accept. A missed inspection on a $120K Lam TCP etch tool that arrived with a cracked quartz liner and a bent transfer arm is a $15K–$30K repair you'll pay for out of pocket.

This inspection takes 2–4 hours. Do it before you sign off on delivery.

Before You Open the Crate

Photograph the crate exterior before a single bolt is removed. Every corner, every wall, every piece of blocking and bracing. If you discover damage later, this is your evidence that it arrived intact — or didn't.

Check the shock watch and tilt indicators if present. Many serious brokers and shippers attach these to tool crates. A triggered shock watch (typically red or pink) doesn't automatically mean the tool is damaged, but it triggers your notification obligation to the carrier. Document it. Photograph it.

Sign the delivery receipt with "subject to inspection" if the driver allows it. Some carriers push back; most accept it. If the crate looks visibly damaged, write the specific damage on the receipt before signing.

Quartz: The First and Most Common Casualty

Quartz components break in transit. Bell jars, process tubes, liners, shower heads — they're fragile, they're expensive, and carriers don't care. A quartz process tube for a furnace runs $800–$4,000. A P5000 CVD showerhead is $4,000–$12,000.

Unpack quartz separately, visually inspect every piece under adequate light, and run your finger along any edge that would be stressed in shipping. Hairline cracks are not visible from arm's length. A cracked quartz component that makes it into a high-temp process run will contaminate the chamber and potentially shatter — which means another quartz purchase plus a $10K–$25K chamber clean.

Set aside any suspect quartz for careful review. Don't install it until you're certain.

Transfer Arms and Robot Mechanisms

Articulated robot arms on atmospheric and vacuum transfer modules are calibrated assemblies. They're not designed to survive a hard impact. Visually inspect the arm for any bending, cracked end-effector, or displaced guide rails. Rotate it through its range of motion by hand (power off, in maintenance mode) before you attempt automated movement.

A bent transfer arm on a 200mm cluster tool costs $3,000–$12,000 to replace and 2–4 days of installation work. A bent arm that you don't catch until the first wafer move destroys the wafer and may crash the robot into the chamber wall. Chamber crash = full chamber inspection + possible rebuild.

Electrical: The Less Obvious Check

Open the electronics enclosures (safely, power off) and look for:

• Loose board connections from vibration
• Dislodged connectors on wiring harnesses
• Any visible burn marks or corrosion that suggest water ingress

High-value electronics — RF generators, mass flow controllers, pressure transducers — are usually better protected but check for loose mounting and any signs of movement. An MFC that shifted in its manifold and broke the process fitting is a $1,500 repair and a potential process gas leak hazard.

Vacuum Hardware Checklist

For any tool with vacuum systems:

• Check all ISO flanges and KF connections for bent flanges or cracked o-ring grooves
• Inspect turbo pump and dry pump mounting — they should be secure, no play in the mounting feet
• Look at roughing lines for cracked fittings, especially at elbow joints where vibration concentrates stress
• Verify gate valve actuators are straight and undamaged

A cracked KF fitting on a roughing line is $30 to fix. A bent ISO-160 flange on a turbopump inlet may require a $400–$1,500 flange replacement. Neither will kill you. A turbopump that got impacted and has bent vanes is $2,000–$8,000 to replace and you won't know until you spin it up.

What the Seller Owes You vs What's Now Your Problem

If the tool was inspected, tested, and documented before shipment, and you accepted a packed, crated tool: shipping damage is generally a carrier/insurance claim, not a seller problem. The seller's obligation ended when the tool was properly packed and handed to the carrier.

Where sellers have liability: if they misrepresented condition (tool was listed as "tested working" but electrical damage pre-existed), or if packing was negligent (quartz shipped loose, no blocking), or if specific damage is documented in photos taken before crating that they didn't disclose.

Most disputes in used equipment are about expectations, not malice. Get inspection photos from the seller before shipping. If they can't provide them, require an independent inspection. $500 for an inspection saves a $15,000 argument later.

Starting the Claim

If you find damage:

1. Stop unpacking. Photograph everything in situ.
2. Note the damage on the delivery receipt if the driver is still present. If not, note it in writing to the broker/seller and carrier within 24 hours.
3. For freight claims, contact the carrier's claims department directly. You'll need: delivery receipt, inspection photos, packing photos if available, repair estimate or parts quote.
4. Most carriers settle concealed damage claims within 30–60 days. Don't wait — the claim window closes.

FAQ

What's the most common damage to semiconductor equipment in shipping? Cracked quartz (liners, tubes, showerheads), bent transfer arms, and loose electrical connections from vibration. Cryo pumps and turbopumps occasionally sustain bearing damage from rough handling.

How long do I have to file a freight damage claim? For visible damage noted on delivery: typically 9 months from delivery for US carriers under Carmack Amendment. For concealed damage (not visible at delivery): 5–15 days from discovery, and discovery means when you first opened and inspected. Don't delay.

Does the seller owe me anything if the equipment is damaged in shipping? Depends on terms. Typically no — once handed to the carrier, shipping damage is a carrier claim. Exception: if the seller packed negligently or misrepresented condition. Get inspection photos before shipment to establish baseline.

What should I ask for from the seller before shipping? Pre-shipment photos of every critical component (quartz, transfer mechanism, vacuum hardware), documentation of how the tool was packed and crated, and a packing list. If they won't provide this, that's information.

Should I get shipping insurance for a $150K used semiconductor tool? Yes. Carrier liability caps at declared value on most freight shipments, often defaulting to low per-pound rates. Separate cargo insurance for high-value equipment runs 0.5–1.5% of declared value and is worth every dollar.

What if I find damage after the crate is fully unpacked? Document immediately, photograph thoroughly, and contact the broker and carrier in writing that day. Your claim window is running from the day the concealed damage was "discoverable," and "I hadn't checked yet" weakens your position significantly.
