Blog review December 16, 2014

Maybe, just maybe, ASML Holding N.V. (ASML) has made the near-impossible a reality by creating a cost-effective Extreme Ultra-Violet (EUV @ ~13.5nm wavelength) all-reflective lithographic tool. The company has announced that Taiwan Semiconductor Manufacturing Company Ltd. (TSMC) has ordered two NXE:3350B EUV systems for delivery in 2015 with the intention to use those systems in production. In addition, two NXE:3300B systems already delivered to TSMC will be upgraded to NXE:3350B performance. While costs and throughputs are conspicuously not-mentioned, this is still an important step for the industry.

The good and the great of the electron device world will make their usual pilgrimage to San Francisco for the 2014 IEEE International Electron Devices Meeting. Dick James of Chipworks writes that it’s the conference where companies strut their technology, and post some of the research that may make it into real product in the next few years.

The 4th Annual Global Interposer Technology Workshop at GaTech gathered 200 attendees from 11 countries to discuss the status of interposer technology. It has become the one meeting where you can find all the key interposer layers including those representing glass, laminate and silicon, blogs Phil Garrou.

Sharon C. Glotzer and Nicholas A. Kotov are both researchers at the University of Michigan who were just awarded a MRS Medal at the Materials Research Society (MRS) Fall Meeting in San Francisco for their work on “Integration of Computation and Experiment for Discovery and Design of Nanoparticle Self-Assembly.”

In order to keep pace with Moore’s Law, semiconductor market leaders have had to adopt increasingly challenging technology roadmaps, which are leading to new demands on electronic materials (EM) product quality for leading-edge chip manufacturing. Dr. Atul Athalye, Head of Technology, Linde Electronics, discusses the challenges.

ST further accelerates its FD-SOI ROs* by 2ps/stage, and reduces SRAM’s VMIN by an extra 70mV. IBM shows an apple-to-apple comparison of 10nm FinFETs on Bulk and SOI. AIST improves the energy efficiency of its FPGA by more than 10X and Nikon shows 2 wafers can be bonded with an overlay accuracy better than 250nm. Adele Hars reports.

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.

At the recent IMAPS conference, Samsung electro-mechanics compared their Plated Mold Via Technology (PMV) to the well known Amkor Through Mold Via  (TMV) technology. The two process flows are compared. Phil Garrou reports.

  1. Diogenes Cicero Says:

    Regarding TSMC’s “order” for two EUV tools, precisely why is this considered “…an important step for this industry”? I bet there was no down payment and that ASML provided TSMC with boatload of incentives and guarantees such that TSMC has virtually nothing at risk. Perhaps TSMC will get the first 450mm 193i tool, who knows. Meanwhile, soft x-ray projection lithography (aka EUV) continues to leave everyone shaking their heads.
