A semiconductor device package includes a dielectric layer and a patterned conductive layer disposed in the dielectric layer. The dielectric layer has a first surface, a second surface opposite the first surface, and a third surface extended from the first surface to the second surface. The semiconductor device package also includes a first electronic component in direct contact with the first surface of the dielectric layer and a first connection structure disposed between the first electronic component and the patterned conductive layer. A method of manufacturing a semiconductor device package is also disclosed.
