Intel unveils 3-D transistors

     SAN FRANCISCO, May 4 (Xinhua) -- Intel Corp. on Wednesday announced that it will mass-manufacture chips using new transistors² featuring a three-dimensional (3-D) structure, calling it a technical breakthrough in microprocessors⁴.

    The 3-D transistor¹, called Tri-Gate, represents a fundamental departure from the two-dimensional planar transistor structure that has powered computers, mobile phones and other modern electronics, Intel said.

    "Intel's scientists and engineers have once again reinvented the transistor, this time utilizing⁵ the third dimension," Paul Otellini, Intel's chief executive officer, said in a statement.

    Intel on Wednesday also demonstrated a 22-nanometer (nm) microprocessor³, codenamed "Ivy⁶ Bridge," which will be the first high-volume chips to use the new 3-D transistors.

    Ivy Bridge is scheduled for high-volume production readiness by the end of this year, the company said.

    According to Intel, the 3-D transistors enable chips to operate at lower voltage with lower leakage⁷ compared to previous transistors, providing up to 37 percent performance increase at low voltage versus⁸ the company's 32nm planar transistors.

    The gain means that the new 3-D transistors are ideal for use in small handheld devices, which operate using less energy to " switch" back and forth⁹, Intel noted¹⁰.（本文由在线英语听力室整理编辑）
