Abstract:
A surface treatment solution includes a fluoride source; a first solvent; and a water transforming agent to transform water produced during wafer surface treatment into a second solvent, which can be the same as, or different from, the first solvent. The solution can be used, for example, in surface preparation for wafers having a backend including an electrical interconnect that includes aluminum or an aluminum alloy.

Claim (Index 12):
A method comprising:\n providing a wafer having a backend comprising an electrical interconnect that comprises aluminum or an aluminum alloy; and removing an oxide of the aluminum or aluminum alloy from the electrical interconnect using a surface treatment solution that comprises:\n a fluoride source; \n a first solvent; and \n a water transforming agent to transform, into a second solvent, water produced during wafer surface treatment.
