Patent ID: 7213336

Claim:
A method for forming an electronic structure, comprising: providing an internally circuitized substrate having a metallic plane on a first surface of the substrate; and forming a redistribution structure including forming N dielectric layers, forming N metal planes, and forming a microvia structure through the N dielectric layers such that the microvia structure electrically couples metal plane N to the metallic plane, wherein N is at least 2, and wherein forming the N dielectric layers and the N metal layers includes setting a dummy index J=0 and looping over J as follows: adding 1 to J; if J=1 then forming dielectric layer 1 on the first surface of the substrate and on the metallic plane, else forming dielectric layer J on dielectric layer J−1 and on metal plane J−1; forming metal plane J on dielectric layer J; and if J<N then returning to adding 1 to J and continuing the looping, else ending the looping.
