Abstract
A silicon integrated circuit device comprising a near intrinsic silicon substrate in which there are one or more ohmic contact regions. An insulating layer lies above the substrate, and on top of the insulating layer is a lower layer of one or more aluminium gates. The surface of each of the lower gates is oxidised to insulate them from an upper aluminium gate that extends over the lower gates.
