Methods of patterning a conductor on a substrate

Abstract

A method of patterning a conductor on a substrate includes providing an inked elastomeric stamp inked with self-assembled monolayer-forming molecules and having a relief pattern with raised features. Then the raised features of the inked stamp contact a metal-coated visible light transparent substrate. Then the metal is etched to form an electrically conductive micropattem corresponding to the raised features of the inked stamp on the visible light transparent substrate.

What is claimed is: 
     
         1 . A touch screen panel comprising:
 a visible light transparent touch sensing area;   a plurality of first regions, each first region comprising an electrically conductive micropattern comprising a plurality of electrically conductive traces having a trace width between 0.5 to 25 micrometers; and   at least one electrically conductive larger feature outside the touch sensing area having a width greater than about 25 microns, wherein the at least one larger feature and the traces comprise a self-assembled monolayer.   
     
     
         2 . The touch screen panel of  claim 1  comprising a plurality of larger features, each larger feature electrically connected to a corresponding first region. 
     
     
         3 . The touch screen panel of  claim 1 , wherein the self-assembled monolayer is disposed on a metal. 
     
     
         4 . The touch screen panel of  claim 1 , wherein the self-assembled monolayer comprises octadecylthiol. 
     
     
         5 . The touch screen panel of  claim 1 , wherein the at least one larger feature comprises a contact pad. 
     
     
         6 . The touch screen panel of  claim 1 , wherein the at least one larger feature comprises an electrically conductive trace for connecting the first regions to a touch sensor drive device. 
     
     
         7 . The touch screen panel of  claim 1 , wherein the first regions have a fill factor between 0.5 and 15%. 
     
     
         8 . The touch screen panel of  claim 1 , wherein the first regions have a fill factor less than 5%. 
     
     
         9 . The touch screen panel of  claim 1 , wherein the at least one larger feature has a fill factor of 1. 
     
     
         10 . The touch screen panel of  claim 1 , wherein the at least one larger feature and the traces comprise a metal. 
     
     
         11 . The touch screen panel of  claim 1 , wherein the at least one larger feature has a width greater than about 100 microns.
