Abstract
The structure in this present invention includes a substrate having a buried-in oxide layer near the surface of the substrate and a silicon surface layer of base over the buried-in oxide layer. After that the structure further includes a conductive layer of gate on the substrate, a dielectric layer on the conductive layer of gate, a metal plug penetrates through the conductive layer and the dielectric layer and reach down to the silicon surface layer but not through. The metal plug, the conductive layer of gate and the silicon surface of base are electrically coupled together.
