I wanted to simulate a stack of metals contacts with Ti/TiN/AlCu/TiN and am wondering what is the proper way to do this?
I made 4 rectangles for cathode and anode( named them cathode0, cathod1, etc), and added contacts in the boundary conditions for the top cathode and anode. This resulted in error saying that some conductors did not have contacts defined. so then I did:
grouped the rectangles into a Structure Group, so 1 structure group for cathode side and one for anode side, then set the contacts to apply to the cathode/anode structure groups instead of just the top cathode/anode. This gave error: “Two contacts are adjacent”. The cathode(or anode) stack defines the layers as zmin0=0 to zmax0=thickness1; then the next rectangle structure is zmin1= thickness1, zmax1=thickness1+thickness2, so one starts at the coordinate where the other ends.
Is this the wrong way/ how do I address the “two contacts are adjacent” issue?
