Manufacturing Bits: July 10


Semicon West It’s Semicon West time again. Here’s the first wave of announcements at the event: Applied Materials has unveiled a pair of tools aimed at accelerating the industry adoption for new memories. First, Applied rolled out the Endura Clover MRAM PVD system. The system is an integrated platform for MRAM devices. Second, the company introduced the Endura Impulse PVD platform for P... » read more

System Bits: Feb. 26


Firefly microstructures in LED light bulbs Pennsylvania State University researchers wanted to improve the energy efficiency of commercial light-emitting diode light bulbs to save even more energy. They found the answer in the lantern surface of fireflies. "LED lightbulbs play a key role in clean energy," said Stuart (Shizhuo) Yin, professor of electrical engineering at Penn State. "Overall... » read more

Power/Performance Bits: July 10


Heating up EV batteries Researchers from Pennsylvania State University developed a self-heating battery that can charge rapidly in cold conditions, a step they hope could spread adoption of electric vehicles. "Electric vehicles are popular on the west coast because the weather is conducive," said Xiao-Guang Yang, assistant research professor in mechanical engineering, Penn State. "Once you ... » read more

Power/Performance Bits: June 5


Self-assembled battery Researchers at Cornell University developed a self-assembling battery capable of near-instant charging. Instead of having the batteries' anode and cathode on either side of a nonconducting separator, the team's new approach intertwines the components in a self-assembling, 3D gyroidal structure, with thousands of nanoscale pores filled with the elements necessary for e... » read more

Manufacturing Bits: Oct. 11


Space elevators Last year, Pennsylvania State University disclosed a technology called benzene-derived carbon nanothreads or sometimes called diamond nanothreads (DNTs). DNTs resemble carbon nanotubes. They are tiny hollow cylindrical tubes that are stronger than steel, but they are also brittle. Basically, DNTs are 1D structures with poly-benzene sections, which are connected by Stone–Wa... » read more

The List Of Unknowns Grows After Silicon


As discussed earlier in this series, most proposed alternative channel schemes depend on germanium channels for pMOS transistors, and InGaAs channels for nMOS transistors. Of the two materials, InGaAs poses by far the more difficult integration challenges. Germanium has been present in advanced silicon CMOS fabs for several technology generations, having been introduced used in strained silicon... » read more

Tunnel FETs Emerge In Scaling Race


Traditional CMOS scaling will continue for the foreseeable future, possibly to the 5nm node and perhaps beyond, according to many chipmakers. In fact, chipmakers already are plotting out a path toward the 5nm node, but needless to say, the industry faces a multitude of challenges along the road. Presently, the leading transistor candidates for 5nm are the usual suspects—III-V finFETs; gate... » read more
