Abstract:In this study, we propose a novel method to quantify the interfacial water trapped at the direct bonding interface. The concept is to intentionally create bonding defects with controlled size and shape, and use them as sensors for the gases generated through the oxidation of a material (in our case, Silicon) by water adsorbed on the surfaces prior to bonding. The evolution of the sensor sizes provides valuable insights into the amount of gas they have trapped, allowing us to analyze the imbibition effect. Anal… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
