A semiconductor device package includes a first conductive layer, a second conductive layer and a third conductive layer. The first conductive layer has a first pitch. The second conductive layer has a second pitch and is arranged at two different sides of the first conductive layer. The third conductive layer has a third pitch and is disposed above the first conductive layer and the second conductive layer. The third conductive layer is electrically connected to the first conductive layer. The first pitch is smaller than the third pitch, and the third pitch is smaller than the second pitch.
