    Abstract: An electronic device and a manufacturing method thereof are provided. The electronic device includes a chip package, a core dielectric layer disposed on the chip package, and an antenna pattern disposed on the core dielectric layer opposite to the chip package. The chip package includes a semiconductor chip, an insulating encapsulation encapsulating the semiconductor chip, and a redistribution structure electrically coupled to the semiconductor chip. The redistribution structure includes a first circuit pattern located at an outermost side of the chip package, and a patterned dielectric layer disposed between the first circuit pattern and the insulating encapsulation. The core dielectric layer is in contact with the first circuit pattern. The core dielectric layer and the patterned dielectric layer are of different materials. The antenna pattern is electrically coupled to the chip package.

    Abstract: Interconnect structures exhibiting reduced accumulation of copper vacancies along interfaces between contact etch stop layers (CESLs) and interconnects, along with methods for fabrication, are disclosed herein. A method includes forming a copper interconnect in a dielectric layer and depositing a metal nitride CESL over the copper interconnect and the dielectric layer. An interface between the metal nitride CESL and the copper interconnect has a first surface nitrogen concentration, a first nitrogen concentration and/or a first number of nitrogen-nitrogen bonds. A nitrogen plasma treatment is performed to modify the interface between the metal nitride CESL and the copper interconnect. The nitrogen plasma treatment increases the first surface nitrogen concentration to a second surface nitrogen concentration, the first nitrogen concentration to a second nitrogen concentration, and/or the first number of nitrogen-nitrogen bonds to a second number of nitrogen-nitrogen bonds, each of which minimizes accumulation of copper vacancies at the interface.
