Inductor structure, magnetically permeable body and manufacturing method thereof

A method of manufacturing a magnetically permeable body, comprising:

• providing an insulating carrier layer;
• forming a first seed layer of a first magnetically permeable group on the insulating carrier layer, electroplating a first magnetically permeable alloy layer of the first magnetically permeable group on the first seed layer via a patterning process, and removing the first seed layer outside a layout range of the first magnetically permeable alloy layer via an etching process;
• and
• forming a second seed layer of a second magnetically permeable group on the first magnetically permeable alloy layer, electroplating a second magnetically permeable alloy layer of the second magnetically permeable group on the second seed layer via a patterning process, and removing the second seed layer outside a layout range of the second magnetically permeable alloy layer via an etching process;
• wherein the first magnetically permeable group and the second magnetically permeable group are stacked in layers on the insulating carrier layer, the first magnetically permeable group includes the first seed layer and the first magnetically permeable alloy layer bonded to the first seed layer, the second magnetically permeable group includes the second seed layer and the second magnetically permeable alloy layer bonded to the second seed layer, and wherein the first seed layer, the first magnetically permeable alloy layer, the second seed layer and the second magnetically permeable alloy layer are sequentially stacked above the insulating carrier layer, and the first magnetically permeable alloy layer and the second seed layer are between the first seed layer and the second magnetically permeable alloy layer.
