    摘要: A method for making an ICD or MEOD structure includes dry etching a structure to produce one or more via holes in an upper layer of the structure. The dry etching step stops on a metal layer that underlies the upper layer in the structure. The method also includes cleaning the dry etched structure with an aqueous solution that includes hydrogen peroxide and either an ammonium salt or an amine salt.

    摘要: Apparatus including: a substrate layer having a substantially planar top surface; an optically conductive peak located and elongated on, and spanning a first thickness measured in a direction generally away from, the top surface; the optically conductive peak having first and second lateral walls each including distal and proximal lateral wall portions, the proximal lateral wall portions intersecting the top surface; and first and second sidewall layers located on the distal lateral wall portions, the sidewall layers not intersecting the top surface and spanning a second thickness that is less than the first thickness measured in the same direction.
