摘要
Silicon wafers, coated with 300 nm evaporated copper, were successfully bonded at 450 degrees C for 30 min with a postbonding anneal in N-2 for 30 min. The postbonding anneal was required for successful bonding, but the annealing temperature did not influence the bond strength from 400 to 620 degrees C. The inclusion of a tantalum diffusion barrier for Cu did not affect the bonding strength or the bonding temperature. (C) 1999 The Electrochemical Society. S1099-0062(99)02-010-6. All rights reserved.
