Hi,
Could we create larger PearlRiver like Testwafers, or is it already the largest size possible on our wafers?
I would like to add some more structures on PearlRiver. Can I just enlarge it, or do I have to replace things? What would be the maximum size?
According to David: "ideally we wanna make the next PearlRiver even smaller, rather than bigger, because the more dies you can fit on one wafer the better you can characterize issues with edge effects" What we could do is splitting the test structures across multiple test wafers based on the complexity level a lab can do. If a lab can't build polysilicon for instance, it's pointless for them to test polysilicon zener diodes."
My idea at the moment is to build a Test Wafer generator which would help us there.
Lets try to discuss this tomorrow in the Mumble call.
Best regards, Philipp
