The present application provides a method for forming chip packages and a chip package. The method comprises arranging a plurality of interconnect devices at intervals on a surface of a carrier and assembling a plurality of chipsets over the interconnect devices. Each chipset comprises at least two chips electrically connected through an interconnect device. A front surface of each chip facing the carrier is provided with a plurality of first bumps. The method further comprises forming a molded package layer whereby the plurality of chipsets and the plurality of interconnect devices are embedded in the molded package layer; removing the carrier and thinning the molded package layer to expose the first bumps; forming second bumps on the surface on one side of the molded package layer where the first bumps are exposed; and dicing the molded package layer to obtain a plurality of package units. Thus, a flexible and low-cost packaging scheme is provided for multi-chip interconnection.
