[SI-LIST] Oscillation killer

Hello All,

I am testing a new IC proto and found an oscillation at several tens of
GHz. After spending quite some time simulating the structures we were able
to identify that the issue was related to coupling as well as the
termination of the line inside the IC. To demonstrate that it was true we
put a drop of H2O on the area where we expected the problem to be and as
simulated the water stopped the oscillation. Of course that was true until
the heat of the IC evaporated the water and oscillation restarted.

This work and we do not have to respin the IC yet but it is a PAIN!!!!

Does anybody knows a material that would work like water but it is more
permanent and does not degrade at temperature between 90 and 120 degC?

Thanks

Roger Delbue
