The development of formulated cleans for enabling packaging processes

Packaging processes have been recognized as and developed into viable approaches to enable the continuous scaling of devices together with improvements of costs and reliabilities of theirs. The development of more sustainable cleans for the removal of SnF2 at the interconnect level1, the Bosch-etched PERs (Post Etch residues) at the interposer level and TFRs (thick film resists) at the wafer level in advanced packaging processes will be discussed including their design concepts and performance evaluations.
