Substrate structure

A substrate structure comprises a substrate body having a plurality of insulating layers and a circuit combination bonded to the substrate body and having a passive line, wherein at least the formingmaterial of the insulating layer is a high dielectric constant material, and the capacitor circuit of the circuit combination is Formed on the insulating layer of the high-k material to maintain signal quality while reducing the overall line area of the line combination. 种基板结构，包括具多个绝缘层的基板本体以及结合至该基板本体且具有被动线路的线路组合，其中，至少该绝缘层的成形材料为高介电系数材料，使该线路组合的电容线路形成于该高介电系数材料的绝缘层上，以维持讯号品质，同时缩小该线路组合的整体线路面积。
