Abstract:
1. A spherical element having an electrically conductive metal structure disposed thereon prepared by a process comprising the steps of: providing a substrate comprising a first surface comprising a planar portion and a spherical element, defining a continuous metal layer upon and in contact with a surface of the planar portion and with a surface of the spherical element, defining a continuous photoresist layer over the metal layer, defining a solid three-dimensional photoresist structure in the photoresist layer that is in contact with the metal layer on the spherical element and that is in contact with the metal layer on the planar portion, exposing a continuous metal layer area that is in contact with the spherical element and with the planar portion, removing the exposed continuous metal layer area, removing the solid three-dimensional photoresist structure to define a continuous electrically conductive metal structure that is disposed on and in contact with the surface of the planar portion and disposed on and in contact with the surface of the spherical element.
