    摘要: A method for singulating semiconductor wafers is disclosed. A preferred embodiment comprises forming scrub lines on one side of the wafer and filling the scrub lines with a temporary fill material. The wafer is then thinned by removing material from the opposite side of the wafer from the scrub lines, thereby exposing the temporary fill material on the opposite side. The temporary fill material is then removed, and the individual die are removed from the wafer.

    摘要: A method for improving the moisture absorption of porous low dielectric film in an interconnect structure is disclosed. The porous low-k dielectric layer such as porous hydrosilsesquioxane (porous HSQ) or porous methyl silsesquioxane (porous MSQ) is spun-on the etching stop layer. After plasma process, the porous low dielectric film has a plurality of dangling bonds. Then, the wafer is placed in the supplementary instrument with hydrophobic reactive solution. Next, the hydrophobic protection film is formed on surface and sidewall of porous low-k dielectric film to improve the moisture absorption of porous low-k dielectric film and the leakage current is reduced in subsequently processes.

    摘要: A structure of a stacked barrier layer is provided. A first titanium layer is formed on a semiconductor substrate using plasma enhanced chemical vapor deposition (PECVD). At least a stacked barrier layer is formed on the first titanium layer. The stacked barrier layer includes a first titanium nitride layer and a plasma treated titanium nitride layer. The plasma treated titanium nitride layer is treated using a plasma gas including ammonia gas and nitrogen gas.
