World’s fastest IC amplifier Northrop Grumman has set a record for the world’s fastest integrated circuit amplifier. The record has been recognized by officials from Guinness World Records. The amplifier uses 10 transistor stages to reach an operating speed of one terahertz, or one trillion cycles per second. This surpassed the company's own record of 850 billion cycles per second set i... » read more

Confusion Does Not Equal Paralysis
By Ed Sperling - 10 Jul, 2014 - Comments: 0

After attending the two biggest semiconductor conferences in the world, along with a long list of notable conferences targeted to a wide variety of technologies and engineering disciplines, it’s clear the industry is racing ahead. But “ahead” is now a relative term. While Moore’s Law satisfied both economic and technological requirements, it was easy to figure out what “ahead” me... » read more

By Paula Doe The fast growing demand for bandwidth is driving telecomm and data center user interest in moving high speed optical connections closer and closer to the chips, as recent advances in packaging technology, from microbumping to bonding to wafer-level redistribution now help make it possible. Chip-to-chip and chip-to-board optical connections increasingly look like a viable soluti... » read more

Nonlinear optical resonance The drive to develop ultrasmall and ultrafast electronic devices using a single atomic layer of semiconductors, such as transition metal dichalcogenides, has received a significant boost. Researchers with Berkeley Lab have recorded the first observations of a strong nonlinear optical resonance along the edges of a single layer of molybdenum disulfide. The existence ... » read more

Photon glue Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials and this effect could harness the most useful characteristics from each material for hybrid solar cells and high efficiency lighting, among other applications. To this end, researchers at the University of Michigan and Queens Coll... » read more

Experts At The Table: What’s Next?

Semiconductor Engineering sat down with Sumit DasGupta, Si2; Simon Bloch, Samsung; Jim Hogan; Mike Gianfagna, vice president of marketing at eSilicon (VP of corporate marketing at Atrenta when this roundtable was held). What follows are excerpts of that discussion. SE: The future of technology isn’t just about technology. It’s about people and regulations, as well. Where are the hurdles ... » read more

Is There Light At The End Of Moore’s Tunnel?
By Brian Bailey - 18 Dec, 2013 - Comments: 2

Last month’s article, “Is There Light At The End Of Moore’s Tunnel,” examined the state of the industry in terms of integrating photonics components onto silicon. It concentrated on the piece that has been the hardest to achieve – the laser. However, as realizing that integration goal has become closer to reality, it has also waned in terms of the number of people who believe it is th... » read more

Is There Light At The End Of Moore’s Tunnel
By Brian Bailey - 22 Nov, 2013 - Comments: 2

Electrons are slow, clumsy and quite easily distracted. They’re slow because it now takes a signal longer to cross a chip than the period of the clock signal. They often don’t travel in straight lines as they collide with other atoms. And electromagnetic interference between adjacent signals can mess with the information they are transferring. On the other hand, light has none of these p... » read more

Diamond chips The optical transistor, which transports photons, holds great promise. Photons are not only faster than electrons, but they have less crosstalk. But optical transistors are also expensive and difficult to produce. In a possible breakthrough, the ICFO-Institute of Photonic Sciences has demonstrated a “nano-size” diamond that can act as an efficient optical switch. Researche... » read more
