| 摘要 |
To address the above-discussed deficiencies of the prior art, the present invention provides an integrated circuit formed on a semiconductor wafer, comprising a doped base substrate; an insulator layer formed over the doped base substrate; and a doped ultra thin active layer formed on the insulator layer, the ultra thin active layer including a gate oxide, a gate formed on the gate oxide, and source and drain regions formed in the ultra thin active layer and adjacent the gate. The present invention therefore provides a semiconductor wafer that provides a doped ultra thin active layer. The lower Ioff in the DRAM transistor allows for lower heat dissipation, and the overall power requirement is decreased. Thus, the present invention provides a lower Ioff with reasonably good ion characteristics.
