Power/Performance Bits: Jan. 7
By Jesse Allen - 07 Jan, 2020 - Comments: 0

Ferroelectric FET Researchers at Purdue University developed a ferroelectric transistor capable of both processing and storing information. The ferroelectric semiconductor field-effect transistor is made of alpha indium selenide, which overcomes the problem of ferroelectric materials not interfacing well with silicon. “We used a semiconductor that has ferroelectric properties. This way tw... » read more

GaN-on-SOI power semis At the recent IEEE International Electron Devices Meeting (IEDM), Imec and KU Leuven presented a paper on a gallium-nitride (GaN) on silicon-on-insulator (SOI) technology for use in developing GaN power devices. With GaN-on-SOI technology, researchers have developed a 200-volt GaN power semiconductor device with an integrated driver and fast switching performance. ... » read more

Where Technology Breakthroughs Are Needed
By Mark LaPedus - 23 Dec, 2019 - Comments: 2

After years of delays, extreme ultraviolet (EUV) lithography is finally in production at the 7nm logic node with 5nm in the works. EUV, a next-generation lithography technology, certainly will help chipmakers migrate to the next nodes. But EUV doesn’t solve every problem. Nor does it address all challenges in the semiconductor industry. Not by a long shot. To be sure, the industry needs... » read more

High mobility transistor Engineers at the University of Delaware created a high-electron mobility transistor, a device that amplifies and controls electrical current, using gallium nitride (GaN) with indium aluminum-nitride as the barrier on a silicon substrate. Among devices of its type, the team says their transistor has record-setting properties, including record low gate leakage current... » read more

RF GaN Gains Steam
By Mark LaPedus - 21 Nov, 2019 - Comments: 0

Wide-bandgap semiconductors are hot topics these days. One wide-bandgap semi type--silicon carbide (SiC)--is the talk of the town and is gaining steam in electric vehicles and other systems. But let’s not forget about gallium nitride (GaN). GaN, a binary III-V material, has 10 times the breakdown field strength with double the electron mobility than silicon. GaN is used for LEDs, power ... » read more

Market research Smartphone shipments in China stood at 98.9 million units in the third quarter of 2019, down 3.6% year-on-year, according to IDC. Of that, 5G phone shipments in China have grown from virtually zero not long ago to 485,000 units in the third quarter of 2019, according to IDC. Vendors shipped devices amid the launch of commercial 5G services in October. The early smartphone le... » read more

SiC Market Moves Into Overdrive
By Mark LaPedus - 19 Sep, 2019 - Comments: 0

The silicon carbide (SiC) power semiconductor market continues to heat up in the automotive arena. In recent times, several automotive OEMs have formed a series of alliances with SiC device makers, and for good reason. In a major way, many automotive OEMs are entering or expanding their efforts in the battery-electric car market. SiC power semiconductors are among the key components used ... » read more

Wolfspeed GaN: Rugged Enough For Tracking Space Junk, Rugged Enough For 5G
By Wolfspeed, a Cree Company - 18 Sep, 2019 - Comments: 0

GaN RF devices are used throughout the world on projects in a broad range of applications such as surveillance and weather radar, first responder communications, and improvised explosive device (IED) protection systems, where downtime is not an option. But are they rugged and reliable enough to tackle the harshest environments the telecom market can hand out, especially as it relates to 5G smal... » read more

Modeling SiC defects The Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) has developed a model that reveals the nature of crystal defects in silicon carbide (SiC). Defectivity is an issue for SiC, a compound semiconductor material based on silicon and carbon. Today, SiC is used to make specialized power semiconductors for high-voltage applications, such as electric ... » read more

GaN Versus Silicon For 5G
By Kevin Fogarty - 15 Aug, 2019 - Comments: 0

The global race to launch 5G mmWave frequencies could provide a long-anticipated market opportunity for gallium nitride (GaN) as an alternative to silicon. GaN is more power-efficient than silicon for 5G RF. In fact, GaN has been the heir apparent to silicon in 5G power amplifiers for years, especially when it comes to mmWave 5G networks. What makes it so attractive is its ability to efficie... » read more
