Abstract: A fan-out wafer-level packaging method and the package produced thereof are provided in the present application. The method comprises steps including: providing a silicon substrate layer having a first thickness; forming one or more active/passive devices comprising at least sources and drains and one or more diffusion layers adjoining the sources and drains, wherein forming the one or more active/passive devices comprises forming the sources and the drains in a front-end-of-line (FEOL) layer on a first side of the silicon substrate layer while forming the one or more diffusion layers at locations in the silicon substrate layer adjoining the sources and the drains; forming a redistribution layer (RDL) over the FEOL layer by copper damascene formation of multiple metallization layers for connecting the one or more active/passive devices to the one or more IC dies when the one or more IC dies are mounted on a side of the RDL opposite the FEOL layer; thinning the silicon substrate layer to a second thickness to form a thinned silicon substrate, the thinned silicon substrate comprising at least the one or more diffusion layers; and patterning the thinned silicon substrate to form one or more silicon regions, each of the one or more silicon regions comprising the one or more diffusion layers.

Abstract: Various embodiments may provide a semiconductor package. The semiconductor package may include a routing layer including a plurality of first layer contact elements on a first side and a plurality of second layer contact elements on a second side opposite the first side, and a first semiconductor die including a plurality of first electrical die contact elements coupled to the plurality of first layer contact elements. The semiconductor package may further include a second semiconductor die including a plurality of second electrical die contact elements coupled to the plurality of second layer contact elements, and a mold structure covering the second semiconductor die. A first pitch between neighbouring first electrical die contact elements may be greater than a second pitch between neighbouring second electrical die contact elements.
