SAN JOSE, Calif., April 16 /PRNewswire-FirstCall/ -- As semiconductor devices scale to the 32nm technology node and beyond, shrinking contact and via dimensions make chemical vapor deposition (CVD) of tungsten more challenging. Increasing aspect ratios can lead to voids or large seams within device features, resulting in lower yields and decreased performance in microprocessor and memory chips. The International Technology Roadmap for Semiconductors (ITRS) calls for 32nm stacked capacitor...

By Kalinich, John F Vergara, Vernieda B; Emond, Christy A ABSTRACT Novel metal formulations are being used with increasing frequency on the modern battlefield. In many cases the health effects of these materials are not known, especially when they are embedded as fragments. Imaging techniques, although useful for determining location, provide no information regarding the composition of embedded fragments. In this report, we show that laboratory rats implanted with weapons-grade tungsten...
