    摘要: A method of forming a silicon based optical waveguide can include forming a silicon-on-insulator structure including a non-crystalline silicon portion and a single crystalline silicon portion of an active silicon layer in the structure. The non-crystalline silicon portion can be replaced with an amorphous silicon portion and maintaining the single crystalline silicon portion and the amorphous portion can be crystallized using the single crystalline silicon portion as a seed to form a laterally grown single crystalline silicon portion including the amorphous and single crystalline silicon portions.

    摘要: In a method of manufacturing a metal wiring structure, a first metal wiring and a first barrier layer are formed on a substrate, and the first barrier layer is nitridated. An insulating interlayer is formed on the substrate so as to extend over the first metal wiring and the first barrier layer. Part of the insulating interlayer is removed to form a hole exposing at least part of the first metal wiring and part of the first barrier layer. A nitidation plasma treatment is performed on the exposed portion of the first barrier layer. A second barrier layer is formed along the bottom and sides of the hole. A plug is formed on the second barrier layer to fill the hole.

    摘要: A semiconductor device fabrication method having a recess region in an insulation layer on a silicon substrate, includes the steps of depositing a barrier metal on an entire surface of the insulation layer, filling the recess region with an oxide layer, removing the barrier metal on an upper side of the insulation layer, removing the oxide layer in the recess region and exposing the barrier metal of the recess region, depositing a CVD-Al layer on the barrier metal, and depositing a PVD-Al layer on the CVD-Al layer and re-flowing the PVD-Al layer. The fabrication method of a semiconductor integrated circuit according to the present invention selectively removes a barrier metal in the outside of the recess region to expose the insulation layer to the air, and deposits the CVD-Al layer and the PVD-Al layer, which results in controlling abnormal growth of the CVD-Al metal.
