The present technology relates to a circuit board, a semiconductor device, and an electronic apparatus that reduce the generation of noise signals. A circuit board includes: a first conductor layer that has a first conductor portion including a conductor having a planar or mesh-like first basic pattern repeatedly disposed in the same plane; and a second conductor layer that has a second conductor portion including a conductor having a planar or mesh-like second basic pattern repeatedly disposed in the same plane, and a third conductor portion including a conductor having a planar, linear, or mesh-shaped third basic pattern repeatedly disposed in the same plane. The repeating cycles of the first and second basic patterns are substantially the same cycles, and the third basic pattern is different than the second basic pattern. The present technology can be applied to a circuit board of a semiconductor device and the like, for example.

Circuit board, semiconductor device, and electronic apparatus

A laminated wiring board includes a plurality of wiring layers that are stacked with the intermediary of an insulating layer between the layers and have a four-layer wiring unit obtained by disposing a power supply layer, a ground layer, a first signal wiring layer, and a second signal wiring layer sequentially from one side to the other side of a layer stacking direction with the intermediary of an insulating layer between the layers. One of the first signal wiring layer and the second signal wiring layer includes a data signal line and the other includes a clock signal line. The data signal line and the clock signal line are so disposed as to be prevented from overlapping with each other in a view perpendicular to the layer stacking direction at least at a place where both lines are disposed as parallel lines.
