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

Predicting warpage in packages At the recent IEEE Electronic Components and Technology Conference (ECTC) in Las Vegas, there were several papers on ways to predict variation and warpage in IC packages. Advanced packages are prone to unwanted warpage during the process flow. The warpage challenges escalate as the packages become thinner. Warpage in turn can impact yields in IC packages. ... » read more
