    摘要: A method of forming a gate structure. First, a substrate is provided, and a gate oxide layer, a polysilicon layer, a suicide layer, and a cap layer are consecutively formed onto the substrate. Then, an etching process is performed to etch a portion of the cap layer, the silicide layer, and the polysilicon layer and stop on the polysilicon layer for forming a stacked gate. Thereafter, a portion of the silicide layer exposed on sidewalls of the stacked gate is removed to form a recess. A passivation layer is deposited to fill the recess. The remaining polysilicon layer and the gate oxide layer outside the sidewalls of the stacked gate structure are removed.

    摘要: A method of forming shallow trench isolation with chamfered corners. First, a pad insulating layer, a first mask layer, and a second mask layer are sequentially formed on a substrate. The second mask layer, the first mask layer, and the pad insulating layer are patterned to form an opening exposing a portion of the substrate. Next, the substrate is etched using the patterned second mask layer as a mask to form a trench therein. Next, part of the second mask layer is removed to expose the first mask layer adjacent to the trench and result in the second mask layer having a tapered profile. Finally, the second mask layer, the first mask layer, the pad insulating layer, and the substrate are etched along the tapered profile of the second mask layer to chamfer corners of the trench.

    摘要: A process for fabricating interconnects is provided. First, a substrate having a dielectric layer and silicon-containing mask layer on the dielectric layer is provided. The dielectric layer is patterned to form an opening. Thereafter, a metallic glue layer is formed over the silicon-containing mask layer and the interior surfaces of the opening. A metallic layer is formed over the substrate to fill the opening and cover the metallic glue layer. A thermal treatment process is next carried out so that the metallic glue layer reacts with the silicon-containing mask layer to form a metal silicide layer. A portion of the metallic layer is removed to expose the metal silicide layer. A solution mixture containing hydrogen peroxide, sulfuric acid, water and hydrofluoric acid is used to remove the metal silicide layer. The silicon-containing mask layer is also removed to expose the dielectric layer. The solution mixture containing hydrogen peroxide, sulfuric acid, water and hydrofluoric acid can remove the metal silicide layer completely without damaging the metallic layer.

    摘要: A method for fabricating interconnects is provided. The method comprises forming a conducting line on a first dielectric layer; forming a first liner layer on the surfaces of the first dielectric layer and the conducting line; forming a second liner layer on the first liner layer; forming a second dielectric layer on the second liner layer, wherein the etching selectivity rate of the second dielectric layer is higher than the etching selectivity rate of the second liner; and patterning the second dielectric layer to form a contact window opening through the second liner layer and the first liner layer to expose the surface of the conducting line. Because the second dielectric layer having an etching rate higher than the etching rate of the second liner layer, the second liner layer can be used as an etch stop layer while patterning the second dielectric layer.
