Intel Introduces Hafnium to Boost its Chips

Intel says shortly it will begin rolling out microprocessors based on hafnium, rather than silicon. Hafnium is better able to store more electrical charge, is more efficient and runs cooler than an equivalent chip based only on silicon, the company says. The hafnium chips will facilitate performance at the 45nm scale, enabling the company to pack more performance into a given chip. Within the chip, hafnium is used in Hi-k gate dialectrics and metal gates. It reduces electrical current leakage in transistors; a growing problem for chip manufacturers as...
