Fuse simulation

[s0r0s]

Hello everybody!

I'm trying to simulate fuse for 180nm process using CFD software.
Fuse is a piece of Al wire created with top metal and passivation opening above.
I apply power dissipation to it and calculate time-temperature chart.

The problem is that I can't determine the point when my fuse is blown up.
Any solutions on this?

Thanks in advance.

Is this for school?

No. This is kind of my own research and the way to help my colleagues.

I'm curious to know why you're using a fluid dynamics program to simulate electrical destruction of materials for a semiconductor end-product...

The destruction is not electrical, it's themal.
When we talk about power electronics, there is also a electrical influence during arcing time. But in my case, arcing time is minimal.

But if you know proven way to simulate fuse, don't hesitate to shear with us.
