Agere Systems Builds Smallest Transistors Using Novel Insulator Material

Facebook X LinkedIn Email
WASHINGTON, Dec. 6 -- Researchers at Agere Systems said they have built the semiconductor industry's smallest transistors that incorporate a novel insulating material aimed at significantly reducing the power used by silicon chips. The new transistors use hafnium oxide instead of traditional silicon dioxide as the gate insulator -- a thin layer in a transistor that separates the gate, which turns current flow on and off, from the channel through which current flows In recent years, the semiconductor industry has investigated many so-called high-dielectric constant, or "high-k," materials for...Read full article
