摘要： A method for removing polymer as an etching residue is described. A substrate with polymer as an etching residue thereon is provided, and a hydrogen-containing plasma is used to treat the substrate. A wet clean step is then performed to remove the polymer from the substrate. The treatment using hydrogen-containing plasma can change the chemical property of the polymer, so that the polymer can be removed more easily in the subsequent wet clean step.

摘要： The invention shows a method of a surface treatment on a fluorine silicate glass film. At first a fluorine silicate glass layer is deposited on a semiconductor wafer. Partial fluorine ions in the fluorine silicate glass layer are in-situ removed to form a silicon oxide layer of a pre-determined thickness. Then, a photoresist layer is coated on the silicon oxide layer. After an exposing process, a pre-determined latent pattern is formed in the photoresist layer. Finally, after a developing process, the pre-determined latent pattern of the photoresist is removed so as to expose corresponding portions of the silicon oxide layer underneath the latent pattern of the photoresist layer. As a result, the present invention solves a problem that fluorine ions in the fluorine silicate glass layer 24 diffuse to a surface of the fluorine silicate glass layer 24 to combine with water to form hydrofluoric acid, that contaminates the photoresist and leads to reliability issues.

摘要： A method of fabricating an opening or plug. In the process of forming the opening, before a photoresist layer is formed over a dielectric layer, a treatment process is performed to form a film on the dielectric layer, wherein the film can suppress the outgasing phenomenon of the dielectric layer and prevent the later formed photoresist layer from reacting with the running-off composition component from the dielectric layer. Therefore, the problem of incomplete development due to outgasing of the dielectric layer can be solved. Additionally, in the procedure for forming a plug, before a block layer is forming on a surface of a via, a treatment process is performed to form a film on the surface of the via. Therefore, the problem of having defects inside the block layer caused by outgasing of the dielectric layer can be overcome.

摘要： A method of forming a dual damascene structure. A first dielectric layer and a second dielectric layer are sequentially formed over a substrate. A first photoresist layer is formed over the second dielectric layer. Photolithographic and etching operations are conducted to remove a portion of the second dielectric layer and the first dielectric layer so that a via opening is formed. A conformal third dielectric layer is coated over the surface of the second dielectric layer and the interior surface of the via opening. The conformal third dielectric layer forms a liner dielectric layer. A second photoresist layer is formed over the second dielectric layer and then the second photoresist layer is patterned. Using the patterned second photoresist layer as a mask, a portion of the second dielectric layer is removed to form a trench. The patterned second photoresist layer is removed. Conductive material is deposited over the substrate to fill the via opening and the trench. Finally, chemical-mechanical polishing is conducted to remove excess conductive material above the second dielectric layer.
