To keep up, Intel is relying on its manufacturing prowess to shrink the size of the transistors on its processors to 45 nanometers by Nov. 12.
Nanophase can make them 50 nanometers wide, which renders the zinc oxide transparent no more white goop since each crystalline particle is small enough to allow harmless light to pass through.
