One of our Semiconductor Yield Management customers hasn’t logged into their yieldHUB system for a couple of months. On the other hand, their data pipeline adds multiple Gigabytes of STDF and WAT/PCM data every month to the database and they swear by the system. How is it that they rarely log in, yet value yieldHUB so highly?
The company in question has generally high yields and on the odd occasion they might have a yield hit on a couple of wafers which need thorough investigation.
What they told us is that they have setup a multitude of alerts and scheduled reports from within yieldHUB. Their users receive emailed reports every day for their key products and they also receive alerts on their phones if there are issues, say with bins or tests or unexpected outliers. The reports are clear and detailed enough to keep them on top of their manufacturing in minutes per day.
The yieldHUB system generates enough detailed reporting automatically, in PDF format attached to an email, to tell them where they have the issues. They tell us that this saves them many hours a week per engineer compared to their previous system which required logging in, finding data to look at, downloading it and then analysing it in Excel. (Even with yieldHUB they would only have to log in, and no data download would be required).
So there you have it! The success of yieldHUB in their eyes is how much time it is saving them and that the time saved can be used for truly value added activities.
Do you think that receiving daily reports and/or alerts from your yield management system would make your engineers more efficient?
