Abstract:
A Silicon-on-Substrate (â€œSOIâ€ ) device comprising:an SOI substrate of a stack structure of a base substrate, a buried oxide layer and a semiconductor layer; an oxide layer formed to be in contact with the buried oxide layer at the semiconductor layer portion corresponding to a field region so that an active region is defined; a gate electrode pattern having a gate oxide layer, the gate oxide layer only formed on the active region; a source region and a drain region formed inside the active region of the semiconductor layer of both sides of the gate electrode pattern; and a gate electrode line formed on the gate electrode pattern and on the field region so as to interconnect the gate electrode patterns of the respective active regions arranged in a line, wherein the gate electrode pattern and the gate electrode line are made of the same material, and wherein the gate electrode line has a wider width than that of the gate electrode pattern.
