Yieldhub

Yieldhub That screen you’re using is being powered by microchips. Here at yieldHUB, we’re about empowering the companies who build those tiny devices. The result?

Our platform boosts productivity for semiconductor companies during the manufacturing process. Our yield management platform is available worldwide and offers customers sophisticated features. It means engineers spend less time gathering and preparing data during the manufacturing process and can quickly get to the root cause. A faster increase in yield, higher margins and a significant reduction

in scrap. HISTORY

The company was launched in 2005 by Irish founder and engineer John O’Donnell. John realized engineers were spending countless hours looking at sheets of mass data and when he couldn’t find a solution, he decided to do something about it. That’s how yieldHUB was born! Since then the company has rapidly transformed into a leading global name among semiconductor companies. We have employees all around the world including the UK, Europe, Asia and the USA. Top semiconductor companies choose us because we have a group of experienced experts who are ready to listen. yieldHUB is committed to improving its platform and is constantly tweaking and perfecting our technology as the industry evolves. MISSION STATEMENT

The purpose of this page is to keep people informed about what's happening at yieldHUB and within the wider semiconductor industry. It is a safe place for test engineers to share, learn and connect. COMMUNITY GUIDELINES

Deep domain expertise in test engineering is built over years of real manufacturing experience.

Our CEO, John O'Donnell, spent 17 and a half years as a test engineer across global manufacturing in Silicon Valley, Asia and Ireland. An early STDF adopter and contributor to AEC-Q001 📖, he built yieldHUB in 2005 around real production challenges, growing a team of experienced semiconductor professionals because that context matters 💡

yieldHUB was built by test engineers, for test engineers. Today, it supports every engineer from design through to high-volume manufacturing.

From NPI to production, teams use yieldHUB to solve real yield challenges ⚙️ We have helped companies scale from early wafer runs to high-volume production on the same platform 📈

Test escapes are always a big deal.

Even at PPM levels, they lead to:
▪️ Customer returns
▪️ Quality incidents
▪️ Costly root cause investigations
▪️ Reputational damage

They’re often caused by:
▪️ Gaps in test coverage (tests that never fail)
▪️ Missing units in consolidation
▪️ “Stuck” parts that slip through
▪️ Unstable tests

It only takes one escape to create a major issue...

How are you catching them today?

Most yield problems don’t start at final test. They start much earlier ⬇️

When fab data is disconnected from wafer probe and final test, issues are found too late, impacting yield and product quality.

In this clip, John O'Donnell explains how yieldHUB enables earlier wafer acceptance decisions, helping engineers reject wafers before they impact final test yield.

This is especially important in high volume semiconductor manufacturing 🏭, where small wafer level issues can quickly turn into significant yield loss 📈

“What used to take days can now be done in minutes.” 📈

In this video, John O'Donnell shares how Product Engineers are changing the way they work with semiconductor test data.

yieldHUB brings test data together so teams can:
• 📊 Track yield and parametric distributions across lots, wafers and sites
• 🔍 Query and drill into millions of datapoints from wafer probe through final test
• 🔗 Stack wafers and correlate data across probe, final test and multiple flows
• ⚡ Generate plots, bin summaries and comparisons directly from the dataset
• 🌡️ Analyse parametric variation across voltage, temperature and test conditions
• 🎯 Trace devices at unit level and monitor yield stability during ramp

“Knowing the distribution of yield across sites is extremely important… and it’s right in front of you in seconds.”

“We were able to show variation at different voltages and temperatures all in one plot… we improved yield by 4% and it’s now very stable.”

This is what engineering looks like when the data is connected.

If you're working on yield, NPI or test efficiency and want to see how this works in practice.

We’re proud to support customers in Korea’s 🇰🇷 advanced semiconductor sector, where data security and rapid resolution of yield challenges are critical.

In a recent video, our CEO John O'Donnell highlighted an important point 💡 : in some cases, customers run yieldHUB entirely on-premise, meaning we never access their data at all. They retain full control while still benefiting from the platform’s analytics capabilities.

Whether deployed in a secure cloud environment ☁️ or fully on-premise 🏭 , our platform is designed to deliver powerful analytics while keeping sensitive data protected 🔐.

Thanks to Hayoung Chun and Taewon Um for their support and collaboration on this Korean-language blog.

“In highly integrated silicon photonics, disciplined analytics intelligence is essential to scaling chip infrastructure for data center capacity with confidence.” 💡

NewPhotonics, a market leader in highly integrated photonic ICs for AI-era data center scale-out, scale-up and scale-across interconnect, selected yieldHUB as its analytics platform to drive PIC quality and reliability in silicon photonics production.

This reflects yieldHUB’s advanced analytics, ability to support heterogeneous test flows, and rapid root cause identification.

By converting complex electrical, optical and reliability data into clear engineering insight, yieldHUB enables predictable, high-volume production for the most demanding AI workloads.
