| IBM has unveiled its strategy to produce future chips using a 22nm
fabrication process. The company is adopting a technique called
'computational scaling' in order to manufacture circuits small enough to
deliver more powerful and energy-efficient devices.
While current chips such as Intel's are manufactured using a 45nm
process, vendors are already looking ahead to succeeding generations.
Intel plans to introduce 32nm chips in 2009, but chipmakers have hit a
problem in that current lithographic methods are not adequate for
designs as small as 22nm owing to fundamental physical limitations.
IBM said that computational scaling overcomes these limitations by using
mathematical techniques to modify the shape of the masks and the
characteristics of the illuminating source used to image the circuits
for each layer of an integrated circuit.
The company is directly tying the development into its cloud computing
strategy, claiming that the process will enable the production of
smaller, more powerful and energy-efficient devices that will be
required to deliver highly scalable web services. |
