After a semiconductor MPW (Multi-Project Wafer) run, companies receive initial silicon (A0/B0) that must be tracked, managed, and distributed globally. This process—known as engineering sample logistics—includes lot tracking, revision control, dev kit assembly, and international shipping to engineers, OEMs, and partners.
Without a structured system, this stage can slow validation, delay customer engagement, and create traceability risks.
What is an MPW Run in Semiconductors?
A Multi-Project Wafer (MPW) allows multiple semiconductor companies to share fabrication costs by placing multiple chip designs on a single wafer.
MPW runs are commonly used for:
A0 silicon (first silicon)
early validation
prototype testing
What Happens After Tapeout?

After tapeout and fabrication at foundries like:
Taiwan Semiconductor - https://www.tsmc.com
Global Foundries - https://gf.com
your wafers move to OSAT providers such as:
ASE Global - https://aseglobal.com
Amkor Technologies - https://amkor.com
These companies handle:
packaging
testing
shipment preparation
At this point, you receive:
packaged ICs
engineering samples
limited, high-value inventory
The Engineering Sample Logistics Problem

Once silicon arrives, the real operational challenge begins.
Most fabless semiconductor companies don't have a dedicated logistics team. Engineering samples, evaluation boards, and dev kits often need to be received from OSAT partners, shipped worldwide to engineers, OEM partners, and distributors.
Common challenges include:
Receiving international chip shipments
Managing small-batch engineering samples for multiple partners and splitting shipments
Shipping dev kits to engineers globally with additional kitted components from different vendors
Special delicate and detailed handling to split and combine shipments
Handling international documentation
Tracking inventory by Lot / Batch, revision (A0, B0, etc), and serialization
documenting and insuring high dollar delicate shipments
WORKFLOW and TRACKING
1. Global Engineering Sample Distribution
You must ship samples to:
engineers
OEMs
partners
universities
Each shipment requires:
correct revision (A0 vs B0)
correct quantity
controlled access
2. Lot, Batch, and Revision Tracking

Each chip must be tracked by:
wafer lot
assembly batch
silicon revision
This ensures:
traceability
debugging accuracy
controlled distribution
This is where semiconductor engineering sample fulfillment becomes critical:https://www.fulfillmentco.com/engineering-sample-fulfillment
3. Managing High-Value, Low-Volume Inventory
Unlike traditional fulfillment:
inventory is limited
units are high value
errors are costly
Even small mistakes can delay:
validation cycles
customer testing

4. Dev Kit and Evaluation Board Fulfillment
Many companies must also:
assemble evaluation kits
combine components from multiple vendors
ship complete dev kits
This requires structured kitting and assembly services:https://www.fulfillmentco.com/engraving-blister-clamshell-packaging
5. International Shipping and Compliance

Engineering samples are shipped globally and require:
fast delivery
accurate documentation
NDA-controlled distribution
Why Engineering Sample Logistics Slows Down Teams
Without a system, companies rely on:
spreadsheets
manual tracking
engineers handling logistics
This creates bottlenecks right after tapeout—when speed matters most.
What a Scalable Semiconductor Logistics System Looks Like
To scale after MPW, companies need:
✅ Lot / Batch Tracking
✅ Revision Control (A0, B0, etc.)
✅ Serialization
✅ Controlled Sample Distribution
✅ Inventory Visibility
✅ Dev Kit Fulfillment
Post-MPW Logistics Workflow
Typical flow:
Tapeout→ MPW Run→ OSAT Packaging→ Engineering Samples Received→ Inventory & Lot Tracking→ Dev Kit Assembly→ Global DistributionWhere Fulfillment CO Fits In
Fulfillment CO supports fabless semiconductor companies by:
receiving MPW and OSAT shipments
tracking by lot, revision, and serialization
assembling engineering kits
shipping globally
If you’ve recently completed tapeout, it’s time to build your semiconductor fulfillment workflow

Final Thoughts
MPW runs accelerate innovation—but without proper logistics, they introduce operational complexity.
Companies that move fastest after tapeout treat engineering sample logistics as a core system, not an afterthought.
