    摘要: A method for formation of a segregated interfacial dopant layer at a junction between a semiconductor material and a silicide layer includes depositing a doped metal layer over the semiconductor material; annealing the doped metal layer and the semiconductor material, wherein the anneal causes a portion of the doped metal layer and a portion of the semiconductor material to react to form the silicide layer on the semiconductor material, and wherein the anneal further causes the segregated interfacial dopant layer to form between the semiconductor material and the silicide layer, the segregated interfacial dopant layer comprising dopants from the doped metal layer; and removing an unreacted portion of the doped metal layer from the silicide layer.

    摘要: A method to determine the cleanness of a semiconductor substrate and the quantity/density of pin holes that may exist within a patterned antireflective coating (ARC) is provided. Electroplating is employed to monitor the changes in the porosity of the ARC caused by the pin holes during solar cell manufacturing. In particular, electroplating a metal or metal alloy to form a metallic grid on an exposed front side surface of a substrate also fills the pin holes. The quantity/density of metallic filled pin holes (and hence the number of pin holes) in the patterned ARC can then be determined.
