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

China Speeds Up Advanced Chip Development


China is accelerating its efforts to advance its domestic semiconductor industry, amid ongoing trade tensions with the West, in hopes of becoming more self-sufficient. The country is still behind in IC technology and is nowhere close to being self-reliant, but it is making noticeable progress. Until recently, China’s domestic chipmakers were stuck with mature foundry processes with no pres... » 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

The inverter was designed with a holistic approach with careful consideration of module specifications, busbar technology, DC link capacitors, and a high-performance... » read more

The Ins And Outs Of Silicon Carbide


John Palmour, CTO at Cree, sat down with Semiconductor Engineering to talk about silicon carbide, how it compares to silicon, what's different from a design and packaging standpoint, and where it's being used. What follows are excerpts of that conversation. SE: SiC is well-understood in power electronics and RF, but is the main advantage the ability to run devices hotter than silicon, or is ... » read more

How Silicon Carbide Is Improving Energy Efficiency & Lowering Costs In Industrial Applications


Industrial applications such as server power supplies, uninterruptible power supplies (UPS), and motor drives consume a significant portion of the world’s power. Thus, any increase in the efficiency of any end user power system will substantially reduce a company’s operating costs. Combined with greater power density and better thermal performance, the demand for high-efficiency power suppl... » read more

Meeting Commercial Demands With XM3 Module Platform


While silicon carbide (SiC) is still considered a relatively new material in the semiconductor market, it is now used in power circuitry that supports our everyday lifestyle — from the data centers that deliver our emails, to solar power grids that provide energy to offices and homes, to electric cars and trains we use to commute, and in factory equipment and robots that manufacture the goods... » read more

Demand Picks Up For 200mm


Demand is growing for both 200mm fab capacity and equipment, setting the stage for possible shortages in coming months. But there are also some uncertainties, if not warning signs, in the 200mm market and the entire IC industry. Trade disputes, as well as the current coronavirus outbreak in China, likely will impact the chip and equipment markets. The size of the impact and the duration rema... » read more

SiC Foundry Business Emerges


Several third-party foundry vendors are entering or expanding their efforts in the silicon carbide (SiC) business amid booming demand for the technology. However, making a significant dent in the market will not be so easy for SiC foundry vendors and their customers. They are facing stiff competition from traditional SiC device vendors such as Cree, Infineon, Rohm and STMicroelectronics. ... » read more
