Patent ID: 7746232

Claim:
An electronic substrate comprising: a base substrate having an active face and a rear face; a passivation film formed on the active face of the base substrate; a plurality of inductor elements formed on or above the active face, or formed on or above the rear face, and having a winding wire, the winding wire having an inner end and an outer end; a first electrode and a second electrode formed in an array at a peripheral portion of the active face of the base substrate; a first connecting wire formed on the passivation film and connected to the first electrode; a dielectric layer formed between at least some of the inductor elements and the base substrate so as to cover the first connecting wire, including a through hole in which the inner end of the winding wire is connected to the first connecting wire; and a second connecting wire connected to the outer end of the winding wire, connected to the second electrode, and formed on the dielectric layer.
