So you’re using one of those desktop tools and your company has just purchased yieldHUB. So you’re wondering, is this a good thing or a bad thing? You have invested years into this simple tool and although you find it always took a lot of time to get the right data into it, you were happy once the data was in there.

These tools don't do data management. So now that yieldHUB is available to you, does this make it easier or harder to get your data into your older tool, if at all?

Well actually, you’re in luck. yieldHUB itself is great for analysis but now lets you download to external analysis packages with a preparation step that will take only a couple of minutes of your time. So the time saving sounds good, but, you’re asking, what type of data are we talking about?

yieldHUB data management and data integration

yieldHUB includes a relational database that contains the production datalog data from all your subcons, updated several times a day. Hence all the data management and integration is done within yieldHUB.

The following are the data that are stored and linked up relationally:

Fab PCM/WAT data, Wafer sort and Final Test data (e.g. STDF)
Characterization data for new products
MES data (e.g. actual quantities tested, package type etc)
Genealogy data (eg which wafers from fab are in which final test split)
Inline Fab data when available
Comments and other knowledge sources

Having all this data in a scalable relational database allows powerful analysis within yieldHUB itself.

But I need to download data to use your desktop tool

Currently, you’re not that interested in the analysis that yieldHUB provides. You just want to use with the desktop tool! So you need to download the data into JMP and take it from there.

To answer this need, we updated yieldHUB to do a preparation step for any such download to spreadsheets and desktop tools. This includes all the genealogy information also and MES information. So you have the connected data downloadable, up to 20,000 wafers at a time!

“The [desktop tool] download takes me seconds to set-up even for thousands of wafers. yieldHUB did a great job in making this so easy for me and my team to run very deep analyses.” – Engineer, Korea.

A typical download would be for a few hundreds of wafers of data for several key tests in wafer sort. All the raw data can be included, with summary stats, including Cpk, bin information for each die and the fab lotid for each wafer. The download format is compatible with options such as JMP or Excel, depending on which option you choose.

With all the time you have saved, you should have time freed up to learn about why it may not even be needed to download to in the first place! yieldHUB’s powerful native analysis may save you from paying for that spreadsheet or desktop tool license next year!
