    摘要: A semiconductor device includes a substrate, a pattern including a conductive layer and a hard mask layer stacked over the substrate, a capping layer surrounding sidewalls of the pattern, and a stress buffer layer disposed between the hard mask layer and the capping layer. The stress buffer layer is configured to inhibit transfer of stress between the hard mask layer and the capping layer during a thermal process so as to inhibit leaning of the capping layer.

    摘要: A method for fabricating a semiconductor device includes forming a stacked layer including a tungsten layer, forming a hard mask pattern over the stacked layer, and oxidizing a surface of the hard mask pattern to form a stress buffer layer. A portion of the stacked layer uncovered by the hard mask pattern is removed using the hard mask pattern and the stress buffer layer as an etch mask, thereby forming a first resultant structure. A capping layer is formed over the first resultant structure, the capping layer is etched to retain the capping layer on sidewalls of the first resultant structure, and the remaining portion of the stacked layer uncovered by the hard mask pattern is removed.

    摘要: A method for forming a dual gate oxide layer, including the steps of: a) forming a gate oxide layer on a semiconductor substrate; and b) increasing a thickness of a part of the gate oxide layer by performing a decoupled plasma treatment. Additional heat processes are not necessary because the dual gate oxide layer is formed with the decoupled plasma. Also, the channel characteristic of the semiconductor device can be ensured because the silicon substrate is not damaged. Furthermore, because the threshold voltage in the cell region is increased without additional channel ion implantation, the electrical characteristic of the semiconductor device can be enhanced.
