Parasitic Characterization Comes To Power Design Simulation


Two power design challenges are taking teams into unfamiliar territory. Wide bandgap (WBG) semiconductors target greater efficiency and density. Stricter EMI compliance regulations now come standard in mission-critical industries. Power design practices are still catching up. Simulation often takes a back seat to respinning hardware prototypes until success. What’s missing that could make sim... » read more

Fabrication of GaN/Diamond Heterointerface and Interfacial Chemical Bonding State for Highly Efficient Device Design


Abstract "The direct integration of gallium nitride (GaN) and diamond holds much promise for high-power devices. However, it is a big challenge to grow GaN on diamond due to the large lattice and thermal-expansion coefficient mismatch between GaN and diamond. In this work, the fabrication of a GaN/diamond heterointerface is successfully achieved by a surface activated bonding (SAB) method at r... » read more

Fabs Drive Deeper Into Machine Learning


Advanced machine learning is beginning to make inroads into yield enhancement methodology as fabs and equipment makers seek to identify defectivity patterns in wafer images with greater accuracy and speed. Each month a wafer fabrication factory produces tens of millions of wafer-level images from inspection, metrology, and test. Engineers must analyze that data to improve yield and to reject... » read more

SiC MOSFETs In The Landscape Of Modern Power Devices


Over the years, low losses possible by high breakdown field made silicon carbide (SiC) MOSFETs extremely popular amongst engineers. At present, they are mostly used in areas where IGBTs (Insulated Gate Bipolar Transistors) have been the prevailing component of choice before. But which role do SiC MOSFETs play in today’s landscape of power devices? With SiC MOSFETs (Metal-Oxide-Semicond... » read more

Mobility And 5G Drive Adoption Of New Materials For Power Devices


Electric mobility, renewable energy, and other technology innovations like IoT, 5G, smart manufacturing, and robotics all require reliability, efficiency, and compact power systems, fueling the adoption of silicon carbide (SiC) and gallium nitride (GaN) to support lower voltages in significantly smaller devices. But chip designers must overcome the technological and economical challenges of int... » read more

China Ramps Up Power IC Manufacturing


In addition to changes in power devices being implemented to meet market trends that I discussed in previous posts, there are significant shifts taking place in the locations where these components are manufactured. Over the past 10 years, we’ve seen an increase in power device manufacturing in China, Europe and South East Asia and a subsequent drop off in North America. If we look at ... » read more
