A range of transistors
using thin films of organic or organic compounds as the semiconductors and gate dielectrics are being pursued by organizations in more than 30 countries.
At Lund University in Sweden, Lars-Erik Wernersson and his colleagues have made transistors
in which a solid layer of material is replaced by an airy forest of nanowires (SN: 5/22/04, p.
Furthermore, the multi-gate, FDSOI structure increases the effective width of the electrical path in the transistor
and also provides better electrical control of this path.
It had to be able to apply the different levels of electricity to the transistor
with absolute precision.
The implementation of high-k and metal materials marks the biggest change in transistor
technology since the introduction of polysilicon gate MOS transistors
in the late 1960s," said Intel Co-Founder Gordon Moore.
