Molecular design of moisture insensitive hybrid adhesive films
Abstract/Contents
- Abstract
- Effective bonding of organic/inorganic interfaces is paramount to the structural reliability of modern multilayer device technologies such as flexible electronics, photovoltaics, and nanoelectronic devices, in which organic/inorganic interfaces are ubiquitous. For example, strong adhesion of an underfill epoxy to a silicon substrate is critical to extending the lifetime of advanced integrated circuits and three-dimensional stacking technologies. Often, the synergistic effects of mechanical loads due to thermal expansion mismatch, temperature cycling, and moisture can weaken the adhesion of these polymer-silicon interfaces. The first part of this dissertation focuses on the evaluation of underfill epoxy/silicon interfaces found in microelectronic packages, and their susceptibility to moisture-assisted degradation. The second part of this dissertation explores the design of moisture insensitive and compositionally-graded hybrid organic-inorganic layers to address the challenges related to bonding epoxy/silicon interfaces in humid environments. This work highlights the importance of simultaneously coupling chemical synthesis processes together with optimized solution deposition conditions in order to manipulate the molecular structure of the hybrid films to obtain targeted functionalities, such as the ability to form a high-performance moisture-insensitive bond between a polymeric epoxy layer and an inorganic silicon substrate.
