Sure, the march toward the ridiculous
in the nanometer scale has continued unabated
, but silicon can (probably) take us only so far. Some scientist types at Yale have developed a new fabrication process using bulk metallic glasses (BMGs), which are "amorphous metals" that can avoid crystalizing when cooled in a specific way. The upshot is that the metal -- while seeming solid -- acts as a slow-flowing liquid, with no structure beyond the atomic level. The BMGs can therefore replace several steps in the chip-stamping process, since they're more durable than silicon, but are more pliable than normal metals. Right now the folks at Yale are making patterns as small as 13nm, with better processes to come.
