Abstract:
1. A method of making a circuitized substrate, said method comprising: providing a polytetrafluoroethylene dielectric layer; immersing said polytetrafluoroethylene dielectric layer in a solution including a conductive monomer and a seed material for a predetermined time period; removing said polytetrafluoroethylene dielectric layer from said solution including said conductive monomer and said seed material and thereafter rinsing and drying said polytetrafluoroethylene dielectric layer; and thereafter electrolessly plating a plurality of copper circuit lines on said polytetrafluoroethylene dielectric layer, each of said copper circuit lines having a peel strength within the range of from about 2.3 to about 3.5 pounds per square inch.
