An article is formed as a substrate having a projection extending
outwardly therefrom. The article may be a magnetic recording head and the
projection a write pole. The projection has a width in a thinnest
dimension measured parallel to a substrate surface of no more than about
0.3 micrometers and a height measured perpendicular to the substrate of
not less than about 5 times the width. The article is fabricated by
forming an overlying structure on the substrate with an edge thereon,
depositing a replication layer lying on the edge, depositing a filler
onto the edge and the substrate, so that the filler, the replication
layer, and the overlying structure in combination comprise a continuous
layer on the substrate, selectively removing at least a portion of the
replication layer from a free surface of the continuous layer inwardly
toward the substrate, to form a defined cavity, and depositing a
projection material into the defined cavity to form the projection.
