Abstract
A substrate includes a base layer, first and second circuit layers both coupled to the base layer, a third circuit layer, a fourth circuit layer and two solder resist layers. The first/second circuit layer defines a first/second opening. The third and fourth circuit layers are located at two sides of the first and second circuit layers. The solder resist layers cover outer faces of the third and fourth circuit layers. Each solder resist layer defines a window. The first opening is deviated from the second opening. The third and fourth circuit layers each have a portion exposed to the window to be a solder pad. The first circuit layer and the third circuit layer have a total thickness no more than that of the second circuit layer and the fourth circuit layer. A chip package with the substrate and a method for manufacturing the substrate are also provided.
