PATTERNED ARTICLE INCLUDING ELECTRICALLY CONDUCTIVE ELEMENTS

This abstract first appeared for US patent application 18892610 titled 'PATTERNED ARTICLE INCLUDING ELECTRICALLY CONDUCTIVE ELEMENTS

Original Abstract Submitted

A patterned article includes a unitary polymeric layer and a plurality of electrically conductive elements embedded at least partially in the unitary polymeric layer. Each electrically conductive element includes a conductive seed layer having a top major surface and an opposite bottom major surface in direct contact with the unitary polymeric layer, and includes a metallic body disposed on the top major surface of the conductive seed layer. The metallic body has a bottom major surface and at least one sidewall. The bottom major surface contacts the conductive seed layer. Each sidewall is in direct contact with the unitary polymeric layer and extends from the bottom major surface of the metallic body toward or to, but not past, a top major surface of the unitary polymeric layer. The conductive elements may be electrically isolated from one another. Processes for making the patterned article are described.
