A system
on chip, or SOC, is a type of semiconductor that contains several discrete
components built into one piece of
silicon.
Using the new methods of micromachining, which borrow technology for making computer
chips to carve out and build up microscopic structures
on silicon wafers, Peter Gammel and his colleagues at Bell Labs / Lucent Technologies reduced three of the critical devices of a cell phone to Lilliputian size that will allow all the
components of a phone to be constructed
on a single
chip.
To help do that, the U engineers created a much smaller form of a polarization beamsplitter (which looks somewhat like a barcode)
on top of a
silicon chip that can split guided incoming light into its two
components.
Top - down approaches,
on the other hand, start with a much larger chunk of material and sculpt it into
silicon chips, circuit boards and other microelectronic
components with nanoscale features, by cutting or etching it.
