This study addresses the impact of bath stability on electroplated copper for through-silicon via (TSV) in a controlled manufacturing environment. Microstructure, impurities, and other properties of the copper produced were characterized using an arr
Despite the importance of knowledge in Biology, candidates’ performance at the national examination, The Kenya Certificate of Secondary Education (KCSE) is poor. This could be attributed to the teaching methods. The purpose of this study was to com

SEMATECH evaluated the impact of various process options on the overall manufacturing cost of a TSV module, from TSV lithography and etch through post-plate CMP. The purpose of this work was to understand the cost differences of these options in orde

Even as unit processes for high aspect ratio (HAR) through silicon via (TSV) mid-wafer front-side processing are becoming relatively mature, scaling of the TSVs and reduction of cost of ownership (COO) drive significant innovations in processes, equi

As on-chip interconnect sizes continue to shrink to address the increased device density needs at 7 nm nodes and beyond, copper interconnects start showing an increase of electrical resistivity compared to bulk copper due to the scaling effect. Recen

This paper presents a comprehensive study of the effect of poly(ethylene glycol) (PEG) degradation on the void formation known to take place sporadically at the interface between electroplated Cu and Pb-free solder. Thorough chemical analysis of our

“Kirkendall voiding” in the interfacial Cu3Sn intermetallic compound is often observed in solder joints made between Sn-containing alloys and Cu interconnect pads, during extended thermal aging or electromigration testing. It is commonly believed
