Publication number: 20230138154Abstract: An electronic component includes conductor layers and insulating resin layers which are alternately stacked on a substrate. One of the insulating resin layers positioned in the lowermost layer is smaller in thickness than the insulating resin layers, and the insulating resin layers are smaller in thermal expansion coefficient than the one of the insulating resin layers. Thus, an element that requires high processing accuracy, such as a capacitor, can be embedded in the insulating resin layer positioned in the lowermost layer and having a small thickness, and an element that requires a sufficient conductor thickness, such as an inductor, can be embedded in the insulating resin layers having a large thickness. In addition, since the insulating resin layers each have a small thermal expansion coefficient, the occurrence of warpage and peeling can be suppressed.Type: ApplicationFiled: March 12, 2021Publication date: May 4, 2023Applicant: TDK CorporationInventors: Kazuhiro YOSHIKAWA, Takeshi OOHASHI, Mitsuhiro TOMIKAWA, Futa GAKIYA, Akiyasu IIOKA, Kouichi TSUNODA, Kenichi YOSHIDA
