AMD will implement the strained silicon manufacturing technique on its upcoming 90-nanometer processors as well as 130-nanometer processors.

Strained silicon is a method used by chip makers to widen the path through which electrons move across a chip using a layer of silicon germanium.

Both Intel and IBM use the strained silicon technique to manufacture their 90-nanometer chips. IBM, like AMD, uses an additional technique called silicon on insulator on its 90-nanometer chips.

AMD confirmed this week that it started shipping its 90-nanometer Oakville mobile processors to notebook manufacturers. Desktop and server processors based on the company's 90-nanometer process technology are expected later in the third quarter.

The transition to the 90-nanometer process generation has not gone as smoothly as many chip makers would like. However, AMD claims that it is not suffering from any of the same transition problems that IBM and Intel experienced earlier this year.
