More Rare Earth Rumblings


It’s time to look at the market for rare earths again. Rare earths are chemical elements found in the Earth’s crust. These elements, which are critical, are used in cars, consumer electronics, computers, communications, clean energy and defense systems. So why worry about them? China produces and controls 80% of the world’s rare earths. Other nations depend on China for these materi... » read more

Think Globally, Act Globally


For the last several months, I’ve been working on a series of articles about sustainable manufacturing in the semiconductor industry. How can we, as an industry, reduce our environmental footprint? It’s a big topic, and it’s been challenging to find concrete examples of ways fabs can reduce power consumption, water consumption, and greenhouse gas emissions. I’ll address these topics in ... » read more

Still Searching For Rare Earths


There is both good and bad news for buyers of rare earths. The good news: It’s a buyers’ market. Prices for rare earths remain depressed amid a glut in the marketplace. The bad news: The supplier base is shaky. China still accounts for 85% of the world’s total production of rare earths, but most Chinese suppliers are operating at a loss. And two of the main non-Chinese suppliers, M... » read more
