摘要： A dual damascene process is provided. A dielectric layer is formed on a substrate having a conductive region. The dielectric layer is selectively doped to form a doped region aligned over the conductive region. The doped region, the dielectric layer underlying the doped region, and another part of the undoped dielectric layer are etched until the conductive region is exposed, so that a dual damascene opening exposing the conductive region and a trench are formed, wherein the dual damascene opening comprising a upper trench and a lower via hole. The dual damascene opening and the trench are filled with a conductive layer.

摘要： A retardation layer of a copper damascene process and the fabrication method thereof, to replace the conventional barrier layer with a laminated layer. The laminated layer combines the conventional barrier layer with a porous layer, wherein the porous layer can be formed either above or below the barrier layer to improve the retardation of the copper atom diffusion. Preferably, the porous layer is formed above the barrier layer.

摘要： A method of fabricating salicide. A metal layer is formed on a substrate with a polysilicon gate and a source/drain region. A material layer is then formed on the metal layer, wherein the material is selected to produce compressive stress as compressive stress is produced on the substrate and to produce tensile stress as tensile stress is produced in the substrate. The material layer needs to be chosen with the same stress produced by the metal layer. A thermal process is then performed on the substrate to form a silicide on the polysilicon gate and the source/drain region. The material layer and the unreacted metal layer are removed and therefore the salicide process is accomplished.

摘要： A method of forming a dual alignment photomask. The method includes the steps of depositing a light-blocking layer over a glass plate, and then patterning the light-blocking layer. Next, a switchable mask layer is deposited over the light-blocking layer and the glass plate, after which the switchable mask layer is patterned. Finally, a protective layer is formed over the switchable mask layer, the light-blocking layer and the glass plate. The switchable mask layer can be changed from a light-passing state to a light-blocking state by simply changing the surrounding temperature. Therefore, through proper setting the temperature, the same photomask can be used to form trenches and vias of dual damascene structures. Thus, some mask-making cost can be saved and errors due to mask misalignment can be avoided.

摘要： A method of fabricating a shallow trench isolation structure includes defining a shallow trench isolation region on a substrate covered by a first oxide layer and a mask layer. Then, covering the inner surface of the shallow trench with a silicon nitride layer. After a thermal treatment, two oxide layers are formed at the two sides of the silicon nitride layer, respectively. Then, another oxide layer is formed to fill the shallow trench. Next, a planarization process is performed until the mask layer is exposed. The mask layer and the first oxide layer and the oxide layer higher than the substrate are removed.
