Graphene Puts Nanomaterials In Their Place

Nanomaterials offer unique optical and electrical properties and bottom-up integration within industrial semiconductor manufacturing processes. However, they also present one of the most challenging research problems. In essence, semiconductor manufacturing today lacks methods for depositing nanomaterials at predefined chip locations without chemical contamination. We think that graphene, one of the thinnest, strongest, most flexible and most […]

High-Yield and Ambient-Stable Molecular Devices via Semiconductor Fabrication

A team from IBM Research-Zurich and the Universities of Basel and Zurich developed a new technique to fabricate microelectronic devices by electrically contacting molecules at two well-defined termini. The method allows molecular integration on conventional silicon chips and by standard fabrication methods as used in semiconductor industry. The technique is based on depositing a nanoparticle […]

Future semiconductor research leadership empowered by design automation

This article authored by Myung-hee Na, Senior Technical Staff Member, Semiconductor Technology Research, IBM Research; Karim El Sayed, Director of R&D, Synopsys; Victor Moroz, Synopsys Fellow, Synopsys The number of variables in semiconductor development seem to be inversely proportional to a chip’s dimensions – the smaller our chips get, the more complicated they are to build. […]

Recent papers detail carbon nanotube scalabilty, integration breakthroughs

Carbon nanotubes (CNT) appeal to the semiconductor industry because they’re superior electrical conductors compared to silicon with a mere 1 nanometer body thickness. So why don’t we have CNT chips in everything from mainframes to mobile devices, yet? Scalability of the transistor and large-scale integration are still big challenges. But two papers my colleagues and […]

Using an air cavity to boost the performance of a 5G antenna module

This week the International Microwave Symposium kicks off as part of Microwave Week 2017, where I am giving a talk on new phased array packaging developments for 5G communications. I am part of the RF Circuits and Systems Group at IBM Research which has been actively working on developing new 5G millimeterWave (mmWave) phased array […]

Under pressure: New ptychography technique examines stressed atoms in 3D

In a small lead hutch-protected chamber at Argonne National Labs is a nano-probe that bombards nano-sized electronic devices, like a transistor, for example, with x-rays. Think of it as a CT scan. But for atoms. It’s building a 3D model of that device’s atomic structure, for which we can examine the amount of strain it […]

You asked scientist Jessie Rosenberg anything about silicon photonics

Here’s what she said about flying qubits, wafer-scale photonic test systems, and more Silicon photonics uses light, versus electricity, to send signals from a microchip. IBM engineers use these pulses of light to increase the connectivity and bandwidth between datacenters for faster data transfer over longer distances. But silicon photonics isn’t just for datacenters. IBM […]

Joint program puts “cognitive” in chip manufacturing

Computer chips can fail in countless ways, from countless sources in the manufacturing process. Even with terabytes of sensor data pouring from the manufacturing equipment used to make them, there are still semiconductor lemons, depressing wafer yield, performance and reliability, which drives up manufacturing and speculative maintenance intervention costs. IBM and Tokyo Electron Limited (TELTM) […]
