Your Yield Is Dropping and You Just Can’t See It

Why data delays are holding back chipmakers – and how SQream helps you catch problems before they snowball

In chip manufacturing, tiny details make a huge difference. When yield starts slipping, most fabs only realize it after it’s too late. They dig through test logs, sensor data, and defect maps – long after those wafers have left the building. It’s the usual drill: grab the STDF files, crunch the numbers, refresh the dashboards, and hope you spot what went wrong.

But by then, you’re not fixing the problem. You’re just reporting on the damage.

The Real Problem: Lagging Analytics

It’s not that you don’t have enough data – you’ve probably got more than you know what to do with. The issue is how long it takes to get from raw data to actual insight. Your ATEs are cranking out tons of info, but it often just sits there – unorganized, unanalyzed, and untouched for hours or even days.

As Synopsys and Advantest have pointed out, this delay means problems go unnoticed until it’s too late. Something you could’ve fixed mid-process turns into lost product, extra rework, and blown delivery dates.

This isn’t about yield loss. It’s about how fast you can see what’s going on.

The Go-To Shortcut: Sampling, Scaling Down, and Postmortems

To manage the data overload, fabs often look at just a slice of the data or run partial analyses. But that’s like asking your sharpest engineer to solve a puzzle with half the pieces missing. You miss early signs, rare edge cases, and the subtle stuff that often matters most.

You don’t have all the insights simply because you’re just not seeing the full picture.

Here’s Where SQream Comes In

SQream was built to smash those data bottlenecks. Thanks to GPU power, it lets you analyze every bit of your data – test logs, sensor streams, images – all in near real time.

Forget waiting on overnight jobs. With SQream, you can run heavy-duty queries on massive datasets and get answers in seconds. Spot a misaligned tester before it ruins more wafers. Link image defects with process logs instantly, even across different shifts or factories.

Speak the Same Language – No Matter the Team

Modern fabs aren’t just complex – they’re multilingual. Some teams use Python. Others use SQL. Some might even talk to AI assistants in plain English. SQream makes sure everyone’s speaking to the same data:

• MCP (Model Context Protocol): It’s like a translator between your data and your AI, so both people and systems can run deep workflows without duplicating anything.
• Python-native tools: Stick with tools you already know, like Ibis and RAPIDS. No need for massive rewrites or DevOps tangles.
• Federated queries: Run analysis across different data sources – private cloud, on-prem, hybrid – without needing to move data around. No more ETL slowdowns.

Stop Playing Catch-Up

Here’s the myth: yield loss is just part of life when you’re working at advanced nodes.

Here’s the truth: most yield problems come from delayed insight.

With SQream, you stop reacting and start getting ahead. You catch issues as they happen. Your team spends more time optimizing and less time waiting on data to load.

Your Factory’s Only as Smart as Your Fastest Insight

Smart, AI-driven fabs aren’t some far-off goal – they’re already here. But if your analytics can’t keep up with your data, all that AI talk is just noise.

SQream helps you make near-real-time decisions from your petabyte-scale & complex data sets.

No more chasing yesterday’s problems. It’s time to get ahead of tomorrow.
