Patent attributes
An inductor structure including a first helix winding, a second helix winding, and a shielding structure is provided. The first helix winding has a first exterior wire connecting with a first interior wire in series. The second helix winding and the first helix winding are intercoiled about a symmetric plane. The second helix winding has a second exterior wire connecting with a second interior wire in series and connects with the first interior wire. The shielding structure includes a first shielding layer disposed between the first exterior wire and the substrate corresponding to a projection of the first exterior wire and a second shielding layer disposed between the second exterior wire and the substrate corresponding to a projection of the second exterior wire. The first shielding layer and the second shielding layer are grounded individually, and are in symmetry about the symmetric plane.
