Abstract:
A method of forming a conductive pattern, comprising:providing an article including a metal atom precursor capable of conversion to elemental metal; disproportionately exposing a first portion of the article to electromagnetic radiation at a level greater than exposure at a second portion of the article, in an amount and for a period of time sufficient to convert at least some of the precursor at one of the portions to elemental metal at a conversion level greater than conversion of precursor to elemental metal at the other portion; and depositing metal, from a source external of the metal atom precursor, proximate the portion of the article including metal atom precursor converted at a greater conversion level in an amount greater than deposition of metal at the other portion to form the conductive pattern, wherein a planar dimension of a portion of the conductive pattern is less than about 100 &mgr;m in width.
