Week In Review: Manufacturing, Test


Trade As reported, the U.S. recently implemented more restrictions on U.S. chip sales to Huawei. In response, SEMI has released the following statement in response to the new export control rule changes announced by the U.S. Commerce Department: “SEMI recognizes the role of export control measures to address threats to U.S. national security. However, we are very concerned the new export ... » read more

Power Amp Wars Begin For 5G


Demand is increasing for power amplifier chips and other RF devices for 5G base stations, setting the stage for a showdown among different companies and technologies. The power amplifier device is a key component that boosts the RF power signals in base stations. It's based on two competitive technologies, silicon-based LDMOS or RF gallium nitride (GaN). GaN, a III-V technology, outperforms ... » read more

Week In Review: Manufacturing, Test


Chipmakers Nvidia is in advanced talks to acquire Arm from Softbank, according to numerous reports. In addition, TSMC and Foxconn are looking at possible investments or stakes in Arm, according to a report from Nikkei Asia Review. Infineon posted mixed results for the third quarter of the 2020 fiscal year. "Infineon has so far coped well with the challenging situation caused by the coronavi... » read more

Beyond-Line-Of-Sight Troposcatter Communications Primer


Though tropospheric scatter (troposcatter, or tropo) communications technology has existed since the 1950s and was used by the U.S. military from 1960 to 2002, this legacy technology is being revitalized in the wake of concerns around the reliability of tactical satellite communications (Satcom). For several decades, satellites were a reliable and secure method of communications that provided s... » read more

Atomic Layer Etch Expands To New Markets


The semiconductor industry is developing the next wave of applications for atomic layer etch (ALE), hoping to get a foothold in some new and emerging markets. ALE, a next-generation etch technology that removes materials at the atomic scale, is one of several tools used to process advanced devices in a fab. ALE moved into production for select applications around 2016, although the technolog... » read more

Improving Reliability For GaN And SiC


Suppliers of gallium nitride (GaN) and silicon carbide (SiC) power devices are rolling out the next wave of products with some new and impressive specs. But before these devices are incorporated in systems, they must prove to be reliable. As with previous products, suppliers are quick to point out that the new devices are reliable, although there are some issues that can occasionally surface... » read more

Manufacturing Bits: June 16


GaN power modules Gallium-nitride (GaN) devices are emerging in several markets, such as power semiconductors and RF. GaN, a binary III-V compound, is a wide-bandgap technology, meaning it is faster and more efficient than silicon-based devices. GaN has 10 times the breakdown field strength with double the electron mobility than silicon. Generally, some GaN vendors don’t use a traditio... » read more

The Chemistry Of Semiconductors


At each new process node, the chemistry of chip manufacturing has become much more complex than at previous nodes. But at 5nm and below, it's going to get orders of magnitude more complex. For the first few decades, the chemistry of chips was largely shielded from view for most of the industry. Caustic gases were relatively well understood because they are a potential health hazard, but the ... » read more

Power/Performance Bits: April 14


Undoped polymer ink Researchers at Linköping University, Chalmers University of Technology, University of Washington, University of Cologne, Chiba University, and Yunnan University developed an organic ink for printable electronics that doesn't need to be doped for good conductivity. "We normally dope our organic polymers to improve their conductivity and the device performance. The proces... » read more
