Does your design’s interconnect have high enough wire width to withstand ESD? Frank Feng of Mentor Graphics writes in his blog that although applying DRC to check for ESD protection has been in use for a while, designers still struggle to perform this check, because a pure DRC approach can’t identify the direction of an electrical current flow, which means the check can’t directly differentiate the width or length of a wire polygon against a current flow.

Phil Garrou blogs that most of us know of Nanium as a contract assembly house in Portugal who licensed the Infineon eWLB fan out technology and is supplying such packages on 300mm wafers. NANIUM also has extensive volume manufacturing experience in WB multi-chip memory packages, combining Wafer-level RDL techniques (redistribution) with multiple die stacking in a package.

Gabe Moretti says it is always a pleasure to talk to Dr. Lucio Lanza and I took the opportunity of being in Silicon Valley to interview Lucio since he has just been awarded the 2014 Phil Kaufman award. Dr. Lanza poses this challenge: “The capability of EDA tools will grow in relation to design complexity so that cost of design will remain constant relative to the number of transistors on a die.”

Are we at an inflection point with silicon scaling and homogeneous ICs? Bill Martin, President and VP of Engineering, E-System Design thinks so. I lays out the case for considering Moore’s Law 2.0 where 3D integration becomes the key to continued scaling.

Congratulations to Applied Materials Executive Chairman Mike Splinter on receiving the Silicon Valley Education Foundation’s (SVEF) Pioneer Business Leader Award for driving change in business and education philanthropy by using his passion and influence to make a positive impact on people’s lives.

At the recent FD-SOI Forum in Shanghai, the IoT (Internet of Things) was the #1 topic in all the presentations. As Adele Hars reports, speakers included experts from Synopsys, ST, GF, Soitec, IBS, Synapse Design, VeriSilicon, Wave Semi and IBM.

Jeff Wilson of Mentor Graphics writes that, in IC design, we’re currently seeing the makings of a perfect storm when it comes to the growing complexity of fill. The driving factors contributing to the growth of this storm are the shrinking feature sizes and spacing requirements between fill shapes, new manufacturing processes that use fill to meet uniformity requirements, and larger design sizes that require more fill.

Is 3D NAND a Disruptive Technology for Flash Storage? Absolutely! That’s the view of Dr. Er-Xuan Ping of Applied Materials. He said a panel at the 2014 Flash Memory Summit agreed that 3D NAND will be the most viable storage technology in the years to come, although our opinions were mixed on when that disruption would be evident.

Phil Garrou takes a look at some of the “Fan Out” papers that were presented at the 2014 ECTC, focusing on STATSChipPAC (SCP) and the totally encapsulated WLP, Siliconware (SPIL) panel fan-out packaging (P-FO), Nanium’s eWLB Dielectric Selection, and an electronics contact lens for diabetics from Google/Novartis.

Ed Koczynski says he now knows how wafers feel when moving through a fab. Leti in Grenoble, France does so much technology integration that in 2010 it opened a custom-developed people-mover to integrate cleanrooms (“Salles Blanches” in French) it calls a Liaison Blanc-Blanc (LBB) so workers can remain in bunny-suits while moving batches of wafers between buildings.

Handel Jones of IBS provides a study titled “How FD-SOI will Enable Innovation and Growth in Mobile Platform Sales” that concludes that the benefits of FD-SOI are overwhelming for mobile platforms through Q4/2017 based on a number of key metrics.

Gabe Moretti of Chip Design blogs that a grown industry looks at the future, not just to short term income.  EDA is demonstrating to be such an industry with significant participation by its members to foster and support the education of its future developers and users through educational licenses and other projects that foster education.

The increased performance and the rapid shift from traditional handsets to consumer computing device post a number of manufacturing and supply chain challenges for fabless chip makers. Dr. Roawen Chen of Qualcomm says the scale of the challenges also creates an “extreme stress” for the existing foundry/fabless model to defend its excellence in this dynamic landscape. In a keynote talk at The ConFab, titled “what’s on our mind?” Dr. Chen will deliberate on a number of headwinds and opportunities.

Jean-Eric Michallet, Hughes Metras and Perrine Batude of CEA-Leti describe how the research group has already demonstrated the successful stacking of Si CMOS on Si CMOS, achieving benchmark performance for both layers of transistors. The main process challenge is to develop a sufficiently low-temperature process for the top transistor layer to limit the impact on the lower transistor layers.

Phil Garrou continues his analysis of the IMAPS Device Packaging Conference with a review of the keynote by AMD’s Bryan Black, titled“Die Stacking and High Bandwidth Memory.” Black stated that “…while die stacking is catching on in FPGAs, Power Devices, and MEMs, there is nothing in mainstream computing CPUs, GPUs, and APUs …HBM Stacked DRAM will change this!” Garrou also reviews the newly announced STATSChipPAC FlexLine, which uses eWLB technology to dice and reconstitute incoming wafers of various sizes to a standard size, which results in wafer level packaging equipment becoming independent of incoming silicon wafer size.

Karen Savala, president, SEMI Americas, blogs about the sustainable manufacturing imperative, noting that sustainability is increasingly considered a differentiating factor in global competitiveness relative to the technologies and products being provided. In conjunction with SEMICON West and INTERSOLAR North America, SEMI is organizing a four-day Sustainable Manufacturing Forum to share information about the latest technologies, products, and management approaches that promote sustainable manufacturing.
