GaN Application Base Widens, Adoption Grows


Gallium nitride (GaN) is beginning to show up across a broad range of power semiconductor applications due to its wide bandgap, enabling fast-charging, very high speeds, and much smaller form factors than silicon-based chips. Unlike silicon carbide (SiC), another wide-bandgap technology, GaN is a lateral rather than a vertical device. GaN tops out at about 900 volts, which limits its use in ... » read more

Inspecting, Testing, And Measuring SiC


Achieving the auto industry's stringent zero defect goals is becoming a big challenge for makers of silicon carbide substrates, which are struggling to achieve sufficient yields and reliability as they migrate from 150mm to 200mm wafers and shift their focus away from pure silicon. SiC is a combination of silicon and harder carbide materials, and it has emerged as a key technology for batter... » read more

The Silicon Carbide Race Begins


The growing adoption of silicon carbide (SiC) for a variety of automotive chips has reached the tipping point where most chipmakers now consider it a relatively safe bet, setting off a scramble to stake a claim and push this wide-bandgap technology into the mainstream. SiC holds great promise for a number of automotive applications, particularly for battery electric vehicles. It can extend d... » read more

Cobalt Shortages Ahead


Rapid growth of electric vehicles is creating an enormous demand for cobalt, causing tight supply, high prices and supply chain issues for this critical material. Cobalt is a ferromagnetic metal and one of the key materials used in lithium-ion batteries for cell phones, notebook PCs, battery-electric cars and hybrids. It also is used in alloys and semiconductors. And while the IC industry co... » read more

Data Center Power Poised To Rise


The big power-saving effort that kept U.S. data-center power consumption low for the past decade may not keep the lid on much longer. Faced with the possibility that data centers would consume a disastrously large percentage of the world's power supply, data center owners, and players in the computer, semiconductor, power and cooling industries ramped up effort to improve the efficiency of e... » read more
