Intel to Introduce Microprocessors Based on Hafnium; Aims to Boost Chip Speeds

1:25 PM MST | November 20, 2007 | Alex Scott

Semiconductor maker Intel says it will begin rolling out microprocessors based on hafnium, rather than silicon, next year. Hafnium is better able to store electrical charges, is more energy efficient and runs cooler than an equivalent chip based only on silicon, the company says. The hafnium chips will facilitate performance at the 45-nanometer (nm) scale, enabling the company to pack more transistors onto a given chip. Within the chip, hafnium is used in Hi-k gate dialectrics and metal gates. It reduces electrical current leakage in transistors, which is a...
