    Abstract: Photosensitive, developer-soluble bottom anti-reflective coatings are described. Compositions and methods of forming the same are also disclosed along with resulting microelectronic structures. The anti-reflective compositions comprise a multi-functional epoxy compound having multiple epoxy moieties pendant therefrom and one or more crosslinkable chromophores bonded thereto. The compounds are dispersed or dissolved in a solvent system with a vinyl ether crosslinker and can be used to create crosslinkable and de-crosslinkable coatings for microelectronics fabrication.

    Abstract: Achieving homogeneous and heterogeneous integration for 2.5D and 3D integrated circuit, chip-to-wafer, chip-to-substrate, or wafer-to-wafer bonding is an essential technology. The landing wafer or substrate is bonded with a carrier by using a temporary bonding material before thinning the landing wafer to the desired thickness. Upon completion of redistribution layer formation, Cu pad formation, or other backside processing, dies or wafers with through-silicon vias are stacked onto the landing substrate before molding and singulation. As the landing wafer usually has interconnection metals in the bond line, and those interconnection metals are typically made from lead-free solder alloys, deformation of those solder alloys during thermocompression bonding becomes an issue for manufacturers. To address this issue, a polymeric material with desired strengths is coated on the device wafer to form a conformal protective layer on top of solder alloys, thus enabling temporary bonding and debonding processes.
