With the reliability requirements of automobile microelectronics pushing towards near 0 ppb levels of failure control, halide induced corrosion issues in wire bonded devices have to be tightly controlled to achieve such a high reliability goal. With real-time corrosion monitoring, for the first time we demonstrated that the explosive H2 evolution coupled with the oxygen reduction reaction, occurring at the critical Al/Cu interfaces, is the key driving force for the observed aggressive corrosion. Several types of passivation coating on Cu wire surfaces to effectively block the cathodic H2 evolution were explored with an aim to disrupt this explosive corrosion cycle. The properties of the protective coating were evaluated using various analytical techniques. The surface coating exhibited high thermal stability up to 260 °C (evaluated using TGA analysis). A uniform, highly hydrophobic coating (surface contact angle of >130° with water), was achieved by carefully controlling CVD parameters such as time of deposition, surface control of Cu metal, amount of inhibitor compound loading, temperature of coating process etc. FTIR spectroscopy combined with corrosion screening was used to optimize the CVD passivated coating with strong chemisorption. SEM and EDX, XPS were carried out on various coated surfaces to understand the composition and selectivity …

Brachaid is a collection of photographs that explore the blindness of our perspective that is informed by images. By photographing peripheral landscapes like wastewater processing facilities, the edges of temporary streams, and stormwater basins, the project uses the landscape and its perceived neutrality to foreground how the production of images constructs our perception. The work in Brachaid emphasizes the production of images, from subject and framing choices to the use of imaging software, to demonstrate that such production is regularly and radically obscured in most of the images we consume, and that this same structure exists in our lived reality.

Conducting Opera discusses operas in the standard repertory from the perspective of a conductor with a lifetime of experience performing them. It focuses on Joseph Rescigno’s approach to preparing and performing these masterworks in order to realize what opera can uniquely achieve: a fusion of music and drama resulting in a whole that is greater than the sum of its parts. Opening with a chapter discussing his performance philosophy, Rescigno then covers Mozart’s most-performed operas, standards of the bel canto school including Rossini’s Il barbiere di Siviglia, five of Verdi’s works including La traviata, a selection of Wagner’s compositions followed by French Romantic operas such as Bizet’s Carmen, Puccini’s major works, and finally four operas by Richard Strauss. A useful appendix contains a convenient guide to the scores available online. Conducting Opera includes practical advice about propelling a story forward and bringing out the drama that the music is meant to supply, as well as how to support singers in their most difficult moments. Rescigno identifies particularly problematic passages and supplies suggestions about how to navigate them. In addition, he provides advice on staying true to the several styles under discussion.
