Hello All,
Does anybody know the temperature at which a thin film (0.5 um) of Gold
looses its specular property.
In particular, I would like to know the temperature beyond which Gold
looses its good reflectance and becomes rough, for a MUMPS fabricated Gold
on Polysilicon2 layer with a thin Chromium adhesion layer in between.
Thanks,

Vamsee,
I can't give you an exact number but I believe
the roughening occurs around 250C.
