Yieldhub Enterprise Yield Management Platform for Semiconductor & Integrated Photonics | Enabling Real-Time & Smart Manufacturing.

Helping manufacturers improve yield, reduce test costs, accelerate NPI and increase engineering & manufacturing efficiency. ABOUT

yieldHUB is a global Enterprise Yield Management Platform helping semiconductor and integrated photonics manufacturers improve yield, reduce test costs, accelerate New Product Introduction (NPI), and enable Real-Time & Smart Manufacturing. Our platform transforms semiconductor test, manufacturing, quality and reliability data into trusted insights that help engineering and operations teams make faster decisions, identify root causes sooner and improve manufacturing performance. By unifying fragmented data into a single governed platform, yieldHUB increases engineering productivity, improves product quality and reliability, unlocks hidden manufacturing capacity and supports the journey from NPI through to high-volume manufacturing. Trusted by leading fabless semiconductor companies, IDMs, foundries, OSATs and integrated photonics manufacturers worldwide, yieldHUB has been helping manufacturers optimize yield and manufacturing operations for over 21 years. OUR STORY

Founded in 2005 by engineer John O'Donnell, yieldHUB was created to solve a problem every semiconductor engineer faced—spending too much time preparing data instead of solving manufacturing challenges. Today, yieldHUB is a globally trusted platform with customers and employees across Europe, North America and Asia, supporting some of the world's leading semiconductor and photonics manufacturers. OUR MISSION

ITC 2026 kicked off last week, and we went to show you how to speed up your production floor 📈 Without buying a single new tester!

Kevin Robinson, VP Operations, and Carl S. Moore, Yield Management Specialist, were at booth 602!

Here’s what a 5-minute demo of yieldHUB Live will show you:
- Where your test floor is losing time right now.
- How much of it you can get back, this quarter.
- How Allegro MicroSystems cut unnecessary retest, lifted OEE & first pass yield from the equipment they already owned.

SEMICON West 2026 kicked off last, and yieldHUB was based at the Silicon Island Pavilion in San Francisco 🌉

John O'Donnell and Gillian O'Donnell were there Tuesday to Thursday with Enterprise Ireland USA, and we were asking every test and operations leader the same question:
- How do you speed up production without buying more testers?
- Allegro MicroSystems answered it with yieldHUB Live. They freed up capacity they already had, lifting first pass yield & OEE without adding a single tester.

Congratulations to Marco Paolucci on winning the Irish wh***ey at our booth this afternoon 🥃☘️🎉

Day 2 @ ITC 2026 & the theme of the day: most teams find out what went wrong after the lot ends. By then the time is gone.

Allegro MicroSystems had the same problem.

With yieldHUB Live, they act during the lot, not after it. Higher OEE, First Pass Yield & reduced retest. Zero new hardware.

Final day at SEMICON West, and what a week it's been! 🎊 👏

Yesterday’s exclusive slot at the Silicon Island Pavilion ran demos back to back, and every conversation came back to one thing: everyone can see what went wrong after the lot.

Almost nobody can act on it during the lot. That’s what yieldHUB Live changes.

Last Wednesday night at Ireland House was a true highlight 🇮🇪 🥂. Thank you to Enterprise Ireland USA and IDA Ireland for bringing Ireland’s leading semiconductor companies together, united by a shared vision for the industry 🤝.

Everyone is talking about fab capacity. Few are talking about where the wafers go next.

SEMI expects 20 new 300mm fabs or lines to start construction in 2026 and $227 billion a year in front-end equipment spend by 2029. Every one of those wafers still has to cross a test floor, and that floor isn't in the headline number.

Most high-volume test floors already have a line's worth of capacity hiding in OEE lost to decisions made after the lot has finished instead of while it's running.

Allegro MicroSystems went looking for it. Target: 1% OEE gain. Result: several %, higher first pass yield, significant direct variable cost savings and enough recovered capacity to defer capex. No test program changes, no added test time, no new hardware.

Are you planning test capacity from the testers you own, or the OEE they actually deliver?

yieldHUB Live is a finalist for Agentic AI Innovation of the Year at the 2026 AI Ireland Awards 🏆

Thank you to the judges and congratulations to our fellow finalists.

The proof is on Allegro MicroSystems highest-volume test floor:
- OEE up several % against a 1% target
- Higher First pass yield
- Reduced Retest
- Tester capacity recovered, equipment purchases deferred

No test program changes. No added test time. No new hardware. Running across legacy and modern testers alike.

And the clearest sign this is an agent doing ongoing work, not a one-off analysis, came from Allegro themselves: "If you turn off yieldHUB Live monitoring, the OEE gains will gradually be lost."

If retest or idle time is eating your OEE, message us.

What does 39 years in semiconductor test data analytics teach you?

This Sunday at ITC 2026, our Founder & CEO John O'Donnell returns for the Industry Test Challenges Meeting. Last year he joined the ITC panel on AI for semiconductor test. This year he’s back with a talk of his own and a few lessons that might surprise you about where AI really belongs in the test flow.

For a glimpse of those lessons in action, see how Allegro MicroSystems is getting the most out of its test data.

Join John on October 11th. The room is nearly full, so grab your seat while you still can.

🚨 Big news for semiconductor test: Allegro MicroSystems targeted a one-percentage-point OEE gain. They got several with yieldHUB Live 🎉

Allegro was chasing utilization losses on its highest-volume test floor. yieldHUB Live went after the biggest one ⚡

All without: ⏱️ added test time 🔧 new hardware 💻 test program changes.

"The impact on yield was kind of a revelation to us. We didn't really expect it to have that much of an impact in the first pass and also the final yields." – Eunice Esguerra, Section Manager, Final Test Product Engineering, Allegro MicroSystems Philippines

💰 "When we eventually saw the dollar value, that was a happy surprise." – Eunice

And Allegro's own team is now rolling it out across dozens more testers! 💪

Losing OEE on your test floor? Read how Allegro turned its biggest utilization loss into higher first pass yield, recovered tester capacity and real savings with yieldHUB Live.

Massive thanks to Eunice and the whole Allegro team 🙌
