    • 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. Hence, the depletion effect of the conductive polysilicon gate while operating the device can be suppressed and the device drive-on currents can be further enhanced.
    • 提供一种制造双栅极MOSFET器件的方法。 本发明使用硅层上的氧化碳膜的硬掩模作为蚀刻掩模来蚀刻覆盖掩埋氧化物层的硅层。 结果,从掩埋氧化物层形成源极,漏极和沟道区,并且在掩埋氧化物层的沟道区的下方形成一对凹部。 通道是具有顶表面和两个相对的平行侧壁的翅片结构。 底部凹部形成在翅片结构的每个相对侧壁下方。 导电栅极层跨越翅片结构形成。 导电栅极层的形貌由于在沟道区下面的底部凹陷结构而显着地偏离常规的平滑轮廓,并且可以获得更均匀分布的掺杂的导电栅极层。 因此,可以抑制在操作器件时导电多晶硅栅极的耗尽效应,并且可以进一步提高器件驱动电流。
