Recent News in Semiconductor, Microwave and Optical Materials

Materials are the foundation of the components and circuits that go into high frequency elec-tronic products. There are enough different activities and developments in materials science, pro-cessing, measurement and manufacturing that it is impossible to provide a comprehensive report in two pages. Instead, we offer a variety of notes, news and overviews of a variety of interesting activities in the realm of semiconductor, microwave and optical materi-als, plus a look at the future. Classic Silicon One indicator of progress in semiconductor materi-als is the continued reduction in size—and resulting increase in transistor density—of CMOS, the silicon workhorse of the semiconductor world.
