Adhesion Strength of CuCr Alloy Films to Polyimide
Keyword(s):
ABSTRACTIn the present work, CuCr alloys with varying Cr content were sputter deposited on polyimide films, and the metal/polyimide thin films were maintained under 85° C/85%R.H. (T/H) conditions for the reliability measurements. Results showed that the peel strength without T/H treatments increased proportionally with the Cr content in the CuCr alloy layer(x) up to 17 at. %, and then saturated. Among the samples studied, the peel strength decreased with hold time under T/H conditions for all the cases, but most drastically for the sample with x=8.5. The very poor peel strength of that sample (x=8.5) was attributed to the occurrence of interfacial failures which were thought to take place along Cr-oxide/polyimide interfaces.
