GaN Power Semi Biz Heats Up

The market for devices based on gallium nitride (GaN) technology is heating up amid the push for faster and more power efficient systems. Today, [getkc id="217" kc_name="GaN"] is widely used in the production of LEDs. In addition, it is gaining steam in the radio-frequency (RF) market. And the GaN-based power semiconductor market finally appears ready to take off, after several false starts ... » read more

What To Do With A GaN PDK

Wolfspeed's Jeremy Fisher provides a hands on demo of how his group achieved a first-pass run of a 40GHz MMIC chip using using a PDK for its 0.14 micron process. [youtube vid=i7dsQG8CTO4] » read more

Will III-V Power Devices Happen?

In a previous blog post, I provided a review of the overall power device market and trends driving changes in device evolution that entail materials innovation. For the industry to make such a shift, the advantages over mature, low-cost silicon technologies must be compelling and something the industry absolutely has to implement. Now I’d like to focus on new materials offering competitive be... » read more

System Bits: Sept. 6

How might AI affect urban life in 2030? In an ongoing project hosted by Stanford University to inform societal deliberation and provide guidance on the ethical development of smart software, sensors and machines, a panel of academic and industrial thinkers has looked ahead to 2030 to forecast how advances in artificial intelligence (AI) might affect life in a typical North American city. Th... » read more

RF GaN Gains Steam

The RF [getkc id="217" kc_name="gallium nitride"] (GaN) device market is heating up amid the need for more performance with better power densities in a range of systems, such as infrastructure equipment, missile defense and radar. On one front, for example, RF GaN is beginning to displace a silicon-based technology for the power amplifier sockets in today’s wireless base stations. GaN is m... » read more

Predictions For 2016: Semiconductors, Manufacturing And Design

Seventeen companies sent in their predictions for this year with some of them sending predictions from several people. This is in addition to the CEO predictions that were recently published. That is a fine crop of views for the coming year, especially since they know that they will be held accountable for their views and this year, just like the last, they will have to answer for them. We beli... » read more

Power/Performance Bits: Dec. 23

GaN building blocks A team of engineers from Cornell University, the University of Notre Dame, and the semiconductor company IQE created gallium nitride (GaN) power diodes capable of serving as the building blocks for future GaN power switches. In spite of having many desirable features as a material, GaN is notorious for its defects and reliability issues. So the team zeroed in on device... » read more

Manufacturing Of Next-Generation Channel Materials

One of the many challenges for the IC developers is to change the channel material to increase transistor mobility. But what about manufacturing? Can LED-style epitaxy be migrated to high-volume silicon manufacturing? “The use of Ge and InGaAs quantum wells is an extension of the current strained Si strategy," said Aaron Thean, vice president of process technologies and director of the log... » read more

Chasing After Quantum Dots

In the 1980s, researchers stumbled upon a tiny particle or nanocrystal with unique electrical properties. These mysterious nanocrystals, which are based on semiconductor materials, were later named quantum dots. Quantum dots were curiosity items until 2013, when Sony launched the world’s first LCD TV using these inorganic semiconductor nanocrystals. Basically, when inserted into an LCD TV,... » read more

Bigger, Brighter TVs

The flat panel display (FPD) industry is undergoing a renaissance, with suppliers rolling out a dizzying array of new, high-resolution technologies for mobile devices, computers and TVs. But despite being in the eye of the innovation storm, FPD equipment makers remain cautious—and for good reason. There are a slew of new LCD fabs being built today, mostly in China. This, in turn, is promp... » read more
