摘要:
A MOS transistor is formed on a single crystal silicon substrate doped to form a conductive layer of a first type, and includes: an active region formed on said substrate; a source region and a drain region located in said active region, doped to form conductive channels of a second type; a metal gate region located in said active region between said source region and said drain region, wherein said metal gate has a width of less than one micron; a gate oxide region located over said gate region; an oxide region located over the structure; and a source electrode, a gate electrode and a drain electrode, each connected to their respective regions, and each formed of a combination of a contact metal and an electrode metal. An alternate embodiment includes a pair of MOS transistors which have an interconnect between their gate electrodes and the drain electrode of one transistor and the drain electrode of the other transistor.
