Microvia Formation in 5- $\mu \text{m}$ -Thick Dry-Film Dielectric by Ozone Etch Processes
Yuya Suzuki,Eric Snyder,Chengxiang Ji,Steve Walther,Atul Gupta,Christiane Gottschalk,Venky Sundaram,Rao Tummala +7 more
TL;DR: In this article, the authors used ozone gas as a massively parallel etch process to create microvias with 20-μm diameter and 5μm depth for large panel applications.
Book ChapterDOI
Inductors: Micro- to Nanoscale Embedded Thin Power Inductors
TL;DR: In this article, the authors present the fundamentals of nanomagnetic materials and designs for inductor cores with various topologies and illustrate their superior performance over traditional materials, including traditional magnetic materials.
Proceedings ArticleDOI
Effect of latching force on socketed BGA packages with Ni-Au coated solder spheres
TL;DR: In this article, the effect of latching force on the mechanical responses of BGA packages fabricated with solder spheres coated with Ni-Au coating was evaluated and results were compared with those for packages with uncoated solder spheres.
Journal ArticleDOI
Oxide composition studies of electrochemically grown tantalum oxide on sintered tantalum using XPS depth-profiling and co-relation with leakage properties
Parthasarathi Chakraborti,Parthasarathi Chakraborti,Himani Sharma,Markondeya Raj Pulugurtha,Saumya Gandhi,Saumya Gandhi,Rao Tummala +6 more
TL;DR: In this paper, the chemical structure and leakage properties of electrochemically grown tantalum oxide films on high-surface area tantalum were studied, and the strength of the dielectric film was probed by analyzing the leakage properties.
Proceedings ArticleDOI
Electromagnetic Bandgap Design for Power Distribution Network Noise Isolation in the Glass Interposer
TL;DR: In this paper, the authors designed and fabricated Electromagnetic Band-gap (EBG) structures in the glass interposer PDN and analyzed the effectiveness of these EBG structures for the noise suppression in the PDN.
