When to Use TopMetal2

ChrisDG

Hi,

I am using a new process that contains both TopMetal1 and TopMetal2. Unfortunately documentation is not very useful on when to use either one. Wondered if anyone had any advice on the following:

1. When to use TopMetal2
2. Which is better for Bonding

Thanks.

    I still don't see how anyone can help you without knowing which specific technology you're using. "BiCmos Process" doesn't cut it. Unless somebody is familiar with the specifics of the process you're using, they're not going to know the benefits and disadvantages of "TopMetal1" and "TopMetal2". They're just names to me - I can't tell you anything about them or why you would choose one over the other. I suspect that is the same for everyone else in these forums unless they a) knew the actual technology you were using and b) were familiar with it. Oh and c) they're not going to break any non-disclosure agreement by revealing information here.

    That's why I think you need to contact the foundry if their documentation isn't clear...

    Regards,

    Andrew.
