High Tech, AgTech, Steinbeck: A Distinctive Note of Silicon in the Salinas Valley Terroir

Keizai Silicon Valley, the organization here promoting network-building as a means of achieving successful US-Japan business relations, put on one of the most interesting programs this past week that I’ve attended year-to-date; a Keizai Silicon Valley panel discussion focused on “Trends in AgTech: Real Needs in the Industry.” Without looking, how far do...

3D IC Test: Now and The Road Ahead

Solutions for 3D IC test are ready today, but they will be more ready tomorrow. At the 2015 ISTFA, I presented a tutorial titled “What is New in 3D, Digital Testing?” and I’ll summarize the main points here. I consider test standards and test challenges, which include known-good-die and testing...

Advanced Packaging and 3D come to MRS Spring Meeting

For the first time ever, the Materials Research Society (MRS) brought its annual Spring meeting to Phoenix. I have never attended this event, as it is deeply academic, and has not been on my radar for 3D or advanced packaging technologies. However, after finding out from fellow SemiSisters, Rozalia Beica,...

Micro and Nano X-ray Tomography of 3D IC Stacks

Advanced packaging, and particularly 3D through silicon via (TSV) integration technologies and the resulting 3D-stacked products, challenge materials and process characterization. For 3D TSV stacking of wafers or dies, die-to-die interconnections like micro solder bumps (e.g. AgSn) and Cu pillars are used. The control of the TSV filling and micro-bump...

Cost Analysis of a Wet Etch TSV Reveal Process

Through silicon via (TSV) technology is a key design element being incorporated into more and more advanced packaging designs today. TSVs offer distinct benefits in form factor and improved performance and can enable new, innovative designs not previously possible. To scale this valuable technology and spark industry adoption, there is...

System-in-Package was the Big Story at IMAPS DPC 2016

“The sum is greater than the whole of its parts.” ~ Aristotle (and Bill Chen) While the technology tracks offered the latest developments in interposer and 3D IC processes, fan-out, wafer-level packaging, flip chip, MEMs, sensors and more, System-in-package (SiP) was the big story of the 2016 MAPS Device Packaging...

2016 Illuminated: Same Bulb, Different Shades?

Collected impressions of 2016 to date: the unfortunate passing of too, too many favorite musicians; the hard-to-escape-from strident bellicosity of our national political campaigns; a winter of welcome, abundant, Northern California rains; along with a plethora of riches in the Silicon Valley conference, symposium, and seminar vein. Take the January...

The HBM Supply Chain is Open for Business!

Last June, AMD made 3D integration history with its introduction of the Fiji gaming processor unit (GPU), which for the first time put high bandwidth memory (HBM) — a true 3D stack integrating memory die with through silicon via (TSVs) — into production. Fiji is a Si interposer-based module comprising...

Miniaturization Trends Drive Growth in SiP Market

With the proliferation of mobile electronic products and the ongoing push for greater functionality in a smaller area, miniaturization has become a key word for system-in-package (SiP). SiP provides increased functionality in a subsystem that can be more cost-effectively assembled into a system. Miniaturization and other technology trends driving SiP...

Intercepting IC Products with a Disruptive Technology Option

Much has been written about the challenges that corporations face – especially established corporations – in adapting to a disruptive technology and the associated paradigm shifts. Most of the tomes on the subject focus on corporate management strategies. My intent is to discuss these challenges from a technology point of view...

Shifting Packaging Landscape brings Both Challenges and Growth

2015 overall was a mixed year for the materials sector in the electronics market, with a general slowdown in PC-related segments offset by continued growth in mobile smart phones and other handheld devices despite industry growth flattening out late in 2015. In 2016, market forecasts indicate some improved growth and...

Success for 3D: What A Difference a Year Makes

During the 2015 European 3D TSV Summit, I drove attendees to distraction by asking each presenter what success looked like to them for 3D integration. The resulting responses became a blog post, What Does Success for 3D Integration Look Like? Now, a year later, I decided to revisit the topic by...

European 3D Summit: Putting 3D Packaging To Work

Now that we’ve determined that advanced wafer level packaging — including embedded technologies, fan-out wafer level packaging, and 3D packaging — add value to the devices in which they are implemented, the next step is understanding which option offers the best cost/performance ratio for specific product applications. One of the...
