1. 0.13 micron is a manufacturing term that refers to the feature size of the poly-silicon gate in the microprocessor. This feature size has a direct correlation to the speed and power requirements of the microprocessor. As feature sizes are reduced, the process speed (MHz) increases while the power requirements decrease correspondingly. 0.13 micron is currently the smallest feature size available in high volume manufacturing, and is used for the highest end desktop Pentium® 4 processors and for the Mobile Intel® Pentium® 4 Processor – M and Mobile Intel® Pentium® III Processor – M. This technology allows for greater speeds than ever before with lower power consumption, resulting in greater performance and longer battery life in thinner, lighter notebooks.
