ADS substrate definition (metal Pass through different oxide layers)
I face 3 problems as :
1. the metal is thicker than oxide layer ,this will calls error;
2.And then,I split the metal to 3 metal layers ,and make them overlay as a metal layer . The thickness of center layer is eqeul to oxide2, this also forbidden.
3. Follow step 2 's idea, I change the center metal to be a vias ,and it no error now. But I don't know if a vias is equal to a metal when meshing and simulation( I have set the vias to be 3D-mesh the same as the metal layer before simulation).
note:the version of ads is 2011
using step 3 's idea the substrate is shown as:
And do I need to set the precedence of the metal layer when they overlay?
Any ideas? thank you very much!
Maybe this helps: Add three metals with your substrates, metal thickness is just a little bit smaller than substrate thickness (in pic: subst: 25mil, metal: 24.99mil), add a very thin substrate layer and use vias for connection.
The question is the excitation, you should investigate if each metal needs a port or just e.g. the middle metal.
I simulate the model as I just said in step 3, the resistance is larger than simulate in sonnet. I think the via is no the same as the metal.......(but maybe sonnet is error)

Thank you ,I will try it ..
Agree, the simulation of the via is not the same simulation with metal. It's different. Maybe try my idea!
it is my mistake that the metal layer thickness is error(to thin).
any one face the problem like this?

I found that using the via to connect two metal cost lots of time ...
Help ~~~~~~~~~
Did you tried my variant? The simulation time will increase because of many vias but maybe the results are helpful!
