Proceedings ArticleDOI
Simultaneous switching noise suppression using hydrothermal barium titanate thin film capacitors
D. Balaraman,Jinwoo Choi,V. Patel,Pulugurtha Markondeya Raj,I.R. Abothu,Swapan K. Bhattacharya,Lixi Wan,Madhavan Swaminathan,Rao Tummala +8 more
TL;DR: In this article, the authors reported the integration of hydrothermal barium titanate thin film embedded capacitors in organic printed wiring boards for simultaneous switching noise suppression, a clock distribution network was designed using a clock driver with one input and four differential outputs.
Proceedings ArticleDOI
First demonstration of a surface mountable, ultra-thin glass BGA package for smart mobile logic devices
Venky Sundaram,Yoichiro Sato,Toshitake Seki,Yutaka Takagi,Vanessa Smet,Makoto Kobayashi,Rao Tummala +6 more
TL;DR: In this article, the authors presented the first demonstration of an ultra-thin glass BGA package that is assembled on to a mother board with standard SMT technology such as double-side RDL wiring with advanced 3 micron ground rules, and microbump assembly of a 10mm silicon test die.
Proceedings ArticleDOI
Real-time protein detection using ZnO nanowire/thin film bio-sensor integrated with microfluidic system
TL;DR: In this paper, a nanoscale semiconducting ZnO based biosensor with integrated microfluidics is designed, fabricated and tested to demonstrate the detection of streptavidin, a commonly used protein.
Proceedings ArticleDOI
First demonstration of drop-test reliability of ultra-thin glass BGA packages directly assembled on boards for smartphone applications
Bhupender Singh,Vanessa Smet,Jae Sik Lee,Gary Menezes,Makoto Kobayashi,Pulugurtha Markondeya Raj,Venky Sundaram,Brian Roggeman,Urmi Ray,Riko Radojcic,Rao Tummala +10 more
TL;DR: In this paper, a drop-test reliability performance of large, ultra-thin glass BGA packages that are directly mounted onto the system board, unlike the current approach of flip-chip assembly of interposers, involving additional organic packages which are then SMT assembled onto boards.
Proceedings ArticleDOI
The role of stiff base substrates in warpage reduction for future high-density-wiring requirements
Sounak Banerji,P. Markondeya Raj,Fuhan Liu,K. Shinotani,Shiv Sankar Bhattacharya,Rao Tummala +5 more
TL;DR: In this article, the role of warpage on future high density wiring requirements is investigated and the impact of the gap between mask and the substrate arising out of war page on the width of fine lines is shown.
