A method for bonding a plurality of substrates includes performing a gas
plasma treatment on the plurality of substrates, and performing a water
plasma treatment on the plurality of substrates. Additionally, a system
for performing low temperature plasma enhanced bonding includes a
substrate housing structure having a substrate receiving volume, a gas
source fluidly coupled to the substrate housing structure, a water vapor
source fluidly coupled to the substrate housing structure, and a
radio-frequency (RF) generator coupled to the substrate housing
structure, wherein the system is configured to perform both a gas plasma
treatment and a water plasma treatment on a substrate.
