  • Patent number: 7423321
    Abstract: A method of fabricating a double gate MOSFET device is provided. The present invention overetches a silicon layer overlying a buried oxide layer using a hard mask of cap oxide on the silicon layer as an etching mask. As a result, source, drain and channel regions are formed extending from the buried oxide layer, and a pair of recesses are formed under the channel regions in the buried oxide layer. The channel is a fin structure with a top surface and two opposing parallelly sidewalls. The bottom recess is formed under each opposing sidewall of the fin structure. A conductive gate layer is formed straddling the fin structures. The topography of the conductive gate layer significantly deviates from the conventional plainer profile due to the bottom recess structures under the channel regions, and a more uniformly distributed doped conductive gate layer can be obtained.

  • Publication number: 20070164325
    Abstract: A three-dimensional multi-gate device has a silicon fin, a gate structure, and a stress-adjusting layer. The gate structure contacts with three surface of the silicon fin to form a three-dimensional gate structure. The stress-adjusting layer is disposed on the gate structure to provide stress along the direction parallel to the channel length of the gate structure. The stress helps promote the mobility of the charges in the channel region under the gate structure and improve the electrical performance such as drive current and DIBL of the three-dimensional multi-gate device.
