A multilayer seed pattern inductor includes: a magnetic body containing a magnetic material; and an internal coil part encapsulated in the magnetic body, wherein the internal coil part includes a seed pattern and a surface plating layer disposed on the seed pattern, the seed pattern being formed as two or more layers.

Multilayer seed pattern inductor, manufacturing method thereof, and board having the same

A coil electronic component includes a magnetic body, wherein the magnetic body includes a substrate, and a coil part including patterned insulating films disposed on the substrate, a first plating layer formed between the patterned insulating films by plating, and a second plating layer disposed on the first plating layer.

Coil electronic component and method of manufacturing the same

A thin film type inductor includes a body and external electrodes disposed on an external surface of the body. The body includes a support member and an internal coil supported by the support member, the internal coil includes an upper coil disposed on one surface of the support member and a lower coil disposed on the other surface thereof, and the upper and lower coils are connected to each other by a via electrode. Heights of a plurality of coil patterns arranged along a first virtual line are substantially equal to each other, and heights of a plurality of coil patterns arranged along a second virtual line increase toward the external surface of the body, where the first virtual line radiates from a center of a core of the body toward the via electrode and the second virtual line radiates in the opposite direction.

Thin film type inductor

A thin film inductor includes a body including a coil part disposed therein, wherein the coil part includes a patterned insulating film disposed on a substrate and a coil pattern formed between the patterned insulating films, the coil pattern having a lower height than the insulating film, such that the coil pattern may be formed in a structure with a high aspect ratio while having a uniform thickness, thereby increasing a cross-sectional area of the coil part and improving direct current resistance (Rdc) characteristics.

Thin film inductor and manufacturing method thereof

A power semiconductor device may include: a first conductivity-type first semiconductor region; a second conductivity-type second semiconductor region disposed above the first semiconductor region; a trench gate penetrating through the second semiconductor region and a portion of the first semiconductor region; a third semiconductor region disposed on both sides of the trench gate and disposed on an inner side of an upper portion of the second semiconductor region; and a device protective region disposed in the third semiconductor region.
