Abstract:
1. A method, comprising: obtaining a first dielectric core having a first metal coating forming a first metalized plane; patterning the first metalized plane; depositing a second dielectric layer over the first metalized plane; depositing a second metal coating over the second dielectric layer forming a second metalized plane; patterning the second metalized plane; depositing a third dielectric layer over the second metalized plane; planarizing the third dielectric layer; depositing a third metal coating over the third dielectric layer forming a third metalized plane; patterning the third metalized plane; drilling a plurality of vias; forming a first plurality of trench grooves between two of the plurality of vias, the first plurality of trench grooves connected with the first metalized plane and the second metalized plane with one of said plurality of trench grooves connected with the first metalized plane, the second metalized plane, and the third metalized plane, the first plurality of trench grooves having a long narrow channel with a length and a width and positioned such that the length of the trench grooves is along a path where added cross-sectional area is desired; and metalizing the trenches.
