PHOENIX, March 10, 2014 /PRNewswire/ -- FlipChip International - (FCI), the global technology leader in flip chip bumping and Wafer Level Packaging announced they will give the following paper at the IMAPS – 10th International Conference and Exhibition on Device Packaging 2014 in Scottsdale Arizona, USA.
Dielectric Laser Via Drilling for Next Generation Wafer Level Processing

The common via formation processes used today for dielectrics in WLCSP RDL and flipchip products typically rely on standard photolithography processing using stepper and 1x aligner equipment and processes. There is considerable interest in using laser via drilling (ablation) in dielectrics for flipchip, RDL inner layers, and WLCSP processing for reduced via dimensions and enabling a broader range of dielectric materials, including inherently non-photosensitive options. This presentation will demonstrate "state of the art" laser ablation process results; through different dielectrics showing improved feature resolution and reduced via opening sizes resulting in significantly improved interconnect density. Laser via drilling is a more simplified process compared to traditional photolithography methods. This presentation will demonstrate how using laser via drilling could dramatically improve the design rules for next generation RDL designs.
The paper will be presented on Tuesday, March 11th at 3:00pm.
Ted Tessier, FCI's CTO commented, "For nearly 2 decades, FCI has been the recognized industry leader in flip chip and WLCSP technology development, due to our unmatched experience in bumping related product and process development and engineering in Phoenix, Arizona and more recently in Shanghai, China. Since its beginnings, FCI has worked closely with our material and equipment suppliers, to identify leading edge technologies that push the limits of wafer level packaging. Minimum via size and capture pad dimensions have long been pinch-points to substantially increasing the interconnection density of redistribution layers. Laser via drilling is a game changing technology that enables significant interconnection density improvements, while also enabling a number of other important material and process improvements."

WebRTC converts the entire network into a ubiquitous communications cloud thereby connecting anytime, anywhere through any point. In his session at WebRTC Summit,, Mark Castleman, EIR at Bell Labs and Head of Future X Labs, will discuss how the transformational nature of communications is achieved through the democratizing force of WebRTC. WebRTC is doing for voice what HTML did for web content.

Containers have changed the mind of IT in DevOps. They enable developers to work with dev, test, stage and production environments identically. Containers provide the right abstraction for microservices and many cloud platforms have integrated them into deployment pipelines. DevOps and Containers together help companies to achieve their business goals faster and more effectively. In his session at DevOps Summit, Ruslan Synytsky, CEO and Co-founder of Jelastic, reviewed the current landscape of...
