#cmc,#confab,#namedropping With dimensional scaling reaching economic limits, each company in the IC fab industry must rely upon trusted connections with customers and suppliers to know which way to go, and the only way to gain trusted connections is through attending live events. Fortunately, whether you are an executive, and engineer, or an investor, there is at least one must-attend event happening these days to keep you informed. We should always…

Trefonas Earns 2016 Perkin Medal
The Society of Chemical Industry (SCI), America Group, announced on May 5, 2016 that Peter Trefonas, Ph.D., corporate fellow in Electronic Materials at Dow Chemical Co (NYSE:DOW), has won the 2016 SCI Perkin Medal. This honor recognizes Trefonas’ contributions in the development of chemicals that enable microlithography for the fabrication of microelectronic circuits. Trefonas will receive the medal at a dinner in his honor on Tuesday, September 13, 2016, at…
RFID Playing Cards “Best Product” at Printed Electronics Europe
Cartamundi, imec and Holst Centre (set up by imec and TNO) recently won the Best Product Award at Printed Electronics Europe for their ultra-thin plastic RFID technology integrated into Cartamundi’s playing cards. In each card, the RFID chip has a unique code that communicates wirelessly to an RFID reader, giving the cards in the game a unique digital identity. The jury recognized the potential of this technology to enhance printed…
Omhi kept us Ultra-Clean
Sadly, I just recently learned from the UCPSS 2016 website that Ohmi-sensei—Professor Doctor Tadahiro Ohmi—passed away in Sendai on 21 February 2016. As the guru of ultra-clean technology, he established the global Ultra Clean Society in 1988, founded the International Symposium of Semiconductor Manufacturing (ISSM) in 1992, served as program committee member of the UCPSS between 1992 and 2006, and was an IEEE Fellow. Ohmi was a Professor of New…
Andy Grove blessed us all
Andy Grove, the man who codified the commercial IC industry dynamic as “Only the Paranoid Survive” died yesterday at the age of 79. His instinctive paranoia derived from his tragic experiences while growing up in Hungary, as referenced by Wikipedia in the prolog to “Swimming Across: a Memoir”: By the time I was twenty, I had lived through a Hungarian Fascist dictatorship, German military occupation, the Nazis’ “Final Solution,” the…
Litho becomes Patterning
Once upon a time, lithographic (litho) processes were all that IC fabs needed to transfer the design-intent into silicon chips. Over the last 10-15 years, however, IC device structural features have continued to shrink below half the wavelength of the laser light used in litho tools, such that additional process steps are needed to form the desired features. Self-Aligned Double Patterning (SADP) schemes use precise coatings deposited as “spacers” on…
3D XPoint uses PCM Material in ReRAM Device
IM Flash pre-announced “3D XPoint”(TM) memory for release later this year, and lack of details has led to widespread confusion regarding what it is. EETimes has reported that, “Chalcogenide material and an Ovonyx switch are magic parts of this technology with the original work starting back in the 1960’s,” said Guy Blalock, co-CEO of IM Flash at the 2016 Industry Strategy Symposium hosted by the SEMI trade group. However, contradicting…
Controlling Polymers to Tune TFTs
Thin-film transistors (TFT) created using only additive process steps could create new low-cost ICs with functionalities beyond silicon, but only if we understand how to control structures at the molecular level. Thin films of conjugated polymers such as poly(3-hexylthiophene) (P3HT) can provide useful conductivity when the electron mobilities are controlled within as well as between molecules. In producing TFTs using such organic macromolecules, we must rigorously control the deposition and…
CMOS-Photonic Integration Thermally Sensitive
As published in the journal Nature, CMOS transistors have been integrated with optical-resonator circuits using complex on-chip sensors and heaters to maintain temperature to within 1°C. While lacking the laser-source, these otherwise-fully-integrated solutions demonstrate both the capability as well as the limitation of trying to integrate electronics and photonics on a single-chip. The Figure shows a simplified schematic cross-section of the device. Lead author Chen Sun—affiliated with UC Berkeley and…
