Thicker surface conductors than internal layers enable easier trimming, broader electrical adjustment, smaller components, and resin protection.
Stacked glass layers with different CTEs and buffer materials limit crack growth while CMILs and PMVs maintain power delivery through the substrate.
A controlled wiring width and T1/T2 coating ratio helps coil substrates prevent shorts while preserving space factor and lowering motor losses.
By shifting the relative lamination position of coil layers, this case tunes inductance precisely while reducing short-circuit risk and flux obstruction.
A ground ring and broken ring terminate magnetic flux around a multi-lobe on-chip inductor, reducing mutual coupling without extra silicon area.
A dual-magnetic ring around a conductive through-core via boosts inductance density and current capacity in package substrates.
Opposed inductor and line sections boost electromagnetic coupling in a compact directional coupler while maintaining isolation.
A stacked spiral inductor structure uses multiple metal layers and vias to form shunt windings.
Segmenting the magnetic flux path with non-magnetic gap layers prevents saturation, ensuring stable inductance and improved DC-superimposed characteristics.
Segmenting iron powder into a dedicated layer protects it from etching degradation while maintaining high inductance.
Vertical spiral inductors reduce silicon area by stacking metal layers through vias, minimizing magnetic field interference from planar device components.
