    Why MOS referred to Metal-Oxide Semiconductor when there is
    typically no Metal-Oxide present ? Should it be Metal-Oxide-Semiconductor
    representing the three layers of the device?

  3. "A metal-oxide-semiconductor (MOS) structure is obtained by depositing a
    layer of silicon dioxide (SiO2) and a layer of metal (polycrystalline
    silicon is actually used instead of metal) on top of a semiconductor die. As
    the silicon dioxide is a dielectric material its structure is equivalent to
    a plane capacitor, with one of the electrodes replaced by a semiconductor."
