Abstract:
A wiring substrate includes a first wiring structure, a second wiring structure stacked on an upper surface of the first wiring structure, and an outermost insulating layer stacked on a lower surface of the first wiring structure. The outermost insulating layer covers a part of a bottom wiring layer of the wiring layers forming the first wiring structure. The second wiring structure has a wiring density higher than that of the first wiring structure. A volume ratio V1/V2 is from 0.8 to 1.5, where V1 represents the volume of the wiring layers forming the entire second wiring structure, and V2 represents the volume of the bottom wiring layer in the first wiring structure.
Abstract:
A multilayer substrate that retains a curved state without causing fluctuations in electrical characteristics includes a main body including a plurality of insulating sheets to be stacked and made of a flexible material. A signal wire extends in the main body. A ground conductor is provided at a positive-direction side in a z-axis direction relative to the signal wire in the main body, and overlaps the signal line in a plan view seen from the z-axis direction. A ground conductor is provided on a negative-direction side in the z-axis direction relative to the signal wire in the main body, and overlaps the signal line in a plan view seen from the z-axis direction. The state in which the main body is curved so that the signal wire defines an arc is retained by plastic deformation of the ground conductors.
