    摘要: A method is provided for forming seed layers in semiconductor device channels or vias by using an inert gas sputter etching technique. The technique etches back the seed layers which results in a reduction of seed layer overhang at the top of the channels or vias, thereby enhancing the subsequent filling of the channel or vias by conductive materials.

    摘要: A method is provided for forming seed layers in semiconductor channel and via openings by using a two-stage approach after lining the channel and via openings with barrier material. First, a low temperature deposition of a seed layer is performed at below the 250° C. at which conductive material agglomeration occurs. Second, a higher temperature deposition of a seed layer is performed at above 250° C. Then, the conductive material is deposited to fill the channel and via openings.

    摘要: A method is provided to enhance endpoint detection during via etching in the processing of a semiconductor wafer. The method includes forming a first process layer and a second process layer above the first process layer. A first masking layer is formed above at least a portion of the second process layer, leaving an outer edge portion of at least the second process layer exposed. Thereafter, an etching process is used to remove the outer edge portion of the first and second layers. Once the etching is complete, the first masking layer is removed, and a second masking layer is formed above the second process layer. The second masking layer is patterned to expose portions of the first process layer, and then an etching process substantially removes the exposed portions of the first process layer to form the vias.

    摘要: A method for producing a dielectric layer in a semiconductor product includes two steps. The first step is forming a fluorinated layer (e.g. SiOF or fluorosilicate glass ("FSG")) which includes a material formed in part with fluorine. The second step is forming a fill layer (e.g. SiO.sub.2) above the fluorinated layer. The fill layer is substantially free of materials formed in part with fluorine. A top surface of the fill layer can be planarized. Surface treatments and oxide caps can be applied to the planarized surface to form fluorine barriers if part of the fluorinated layer is exposed to higher layers. Such a method, and a semiconductor device or integrated circuit manufactured according to the method, allow the dielectric constant of an inter-layer dielectric ("ILD") to be lowered while also minimizing the complexity and expense of the manufacturing process.
