Many Paths To Hafnium Oxide


Equipment and materials suppliers often talk about the fragmentation of integrated circuit processing. While the number of manufacturers has gone down, the diversity of the underlying semiconductor market has increased. Low-power processors for mobile devices, non-volatile memory for solid state disks, and dedicated graphics processors all have different requirements from the traditional ind... » read more

The End Of Silicon?


As transistors shrink, not all device parameters scale at the same rate—and therein lies a potentially huge problem. In recent years, manufacturers have been able to reduce equivalent oxide thickness (EOT) more quickly than operating voltage. As a result, the electric field present in the channel and gate dielectric has been increasing. Moreover, EOT reduction is achieved in part by reduci... » read more

Searching For Rare Earths Again


Rare earths are back in the spotlight again. Rare earths are chemical elements found in the Earth’s crust. They are used in cars, consumer electronics, computers, communications, clean energy and defense systems. The big market for rare earths is magnets. In semiconductor production, rare earths are used in high-k dielectrics, CMP slurries and other applications. Last year, the World Tr... » read more
