Abstract:
1. A semiconductor device comprising: a layer of semiconductor material having an active transistor region defined therein; an isolation trench formed in the layer of semiconductor material adjacent to the active transistor region; a trench liner lining the isolation trench, wherein the isolation trench and the trench liner together form a lined trench; an insulating material in the lined trench; and a layer of high-k gate material overlying at least a portion of the insulating material and overlying at least a portion of the active transistor region, the layer of high-k gate material being divided by the trench liner such that the trench liner separates the high-k gate material overlying the at least a portion of the insulating material from the high-k gate material overlying the at least a portion of the active transistor region.
