The Intel Pentium 4 processor uses a 90nm-process to put the features onto a wafer of silicon, and by some definitions, technology with features smaller than 100 nm are "nanotechnology." The amount of engineering that is required to go into modern day processors is absolutely amazing, and even more so when you consider they are making patterns that are smaller than the wavelength of the light used to imprint them (diffraction!)
