Low temperature Cu bonding with large tolerance of surface oxidation
A novel method of low temperature all-Cu bonding was developed, which has a large tolerance for Cu surface oxidation and can even bond Cu with a thick oxide layer at 250 °C. It is significant for the chip level bonding because traditional methods have strict requirements for surface quality. The key...
