Abstract
A chip carrier structure and method for forming the same having a receptor pad formed therein. The structure comprises a circuitized substrate having a conductive element on the surface, an External Dielectric Layer mounted on the circuitized substrate with an opening positioned above the conductive element to form a microvia. The walls of the microvia are first treated to enhance copper adhesion and then are electroplated to provide a receptor pad. Finally, a solder paste is deposited within the microvia to create a solder deposit or bump.
