Abstract
In Trench-Gate Fin-FET, in order that the advantage which is exerted in Fin-FET can be sufficiently taken even if a transistor becomes finer and, at the same time, decreasing of on-current can be suppressed by saving a sufficiently large contact area in the active region, a fin widthof a channel region becomes smaller than a widthof an active region.
