Beschreibung
Zusammenfassung:Embodiments of the present application provides a MEMS solenoid inductor, including: a silicon substrate, a soft magnetic core, and a solenoid; wherein the soft magnetic core is wrapped inside the silicon substrate, the silicon substrate is provided with a spiral channel, the soft magnetic core passes through a center of the spiral channel, and the solenoid is disposed in the spiral channel. By disposing the soft magnetic core and the solenoid of the inductor inside the silicon substrate completely, the thickness of the silicon substrate is fully utilized, and the obtained inductor has a larger winding cross-sectional area and improved magnetic flux, which increases the inductance value of the inductor; at the same time, the silicon substrate plays a protective role on the soft magnetic core and the solenoid, the strength of the inductor is improved, and the good impact resistance is provided.
