A device, for depositing a layer on a substrate by supplying one or more process gases to a process chamber, includes a susceptor and one or more transmitter coils. The susceptor bearing the substrate can be heated to a process temperature by means of an electromagnetic alternating field generated by the one or more transmitter coils. The one or more transmitter coils have a coating that consists of tin and nickel in order to provide a corrosion-resistant coating, which simultaneously has low emissivity and is therefore effective in the presence of chlorine compounds and moisture.

An inductor manufacturing method includes making a coil with a wire member, the coil has two end portions, bending a dependent segment from one end portion of the coil, and bending a lateral extension from the dependent segment, bending a bent segment from the second end portion of the coil, and bending a lateral segment from the bent segment, a base member is then engaged into a space between the coil and the lateral extension and the lateral segment of the coil for forming a coil assembly, the coil assembly is then engaged into a mold cavity of a mold device and punched together with an iron powder, the lateral extension and the lateral segment of the coil are electroplated with an electroplating layer.

Described are electrodeposition methods, and materials and structures prepared by electrodeposition methods, and devices prepared from the electrodeposited materials.

A method of forming a metal magnetic film includes forming the metal magnetic film by a plating process, wherein the metal magnetic film comprises a permalloy and carbon atoms and a content of the carbon atoms is 0.3 to 3.0 at % based on a total amount of the carbon atoms and metal elements.

Disclosed is a composite electroplating method for sintered NdFeB magnet, including: a process of pre-treating sintered NdFeB magnet, a process of electroplating the pre-treated sintered NdFeB magnet, and a process of cleaning and drying the electroplated sintered NdFeB magnet. The electroplating process forms a composite coating composed of a Zn coating, a ZnNi alloy coating, a Cu coating and a Ni coating on the surface of the sintered NdFeB magnet.

There are provided a chip electronic component and a manufacturing method thereof, and more particularly, a chip electronic component having an internal coil structure capable of preventing the occurrence of short-circuits between coil portions and having a high aspect ratio (AR) by increasing a thickness of a coil as compared to a width of the coil, and a manufacturing method thereof.

An object of the present invention is to provide a novel method for forming an electrolytic copper plating film having excellent adhesion on the surface of a rare earth metal-based permanent magnet. The method of the present invention as a means for achieving the object is characterized in that after a magnet is immersed in a plating solution, a cathode current density of 0.05 A/dm.sup.2 to 4.0 A/dm.sup.2 for performing an electrolytic copper plating treatment is applied thereto over 10 seconds to 180 seconds to start the treatment.
