Abstract:
Multiple bonding layer schemes that temporarily join semiconductor substrates are provided. In the inventive bonding scheme, at least one of the layers is directly in contact with the semiconductor substrate and at least two layers within the scheme are in direct contact with one another. The present invention provides several processing options as the different layers within the multilayer structure perform specific functions. More importantly, it will improve performance of the thin-wafer handling solution by providing higher thermal stability, greater compatibility with harsh backside processing steps, protection of bumps on the front side of the wafer by encapsulation, lower stress in the debonding step, and fewer defects on the front side.
