Abstract: A semiconductor device assembly includes a substrate, a first stack of semiconductor dies disposed directly over a first location on the substrate, and a second stack of semiconductor dies disposed directly over a second location on the substrate and electrically coupled to a second subset of the plurality of external connections. A portion of the semiconductor dies of the second stack overlaps a portion of the semiconductor dies of the first stack. The semiconductor device assembly further includes an encapsulant at least partially encapsulating the substrate, the first stack and the second stack.

Abstract: A method of making a semiconductor device assembly is provided. The method comprises attaching a first semiconductor device to an upper surface of a substrate and disposing a stencil over the upper surface of the substrate. The stencil includes (i) an opening and (ii) a cavity in which the first semiconductor device is disposed. The method further comprises screen-printing an epoxy material into the opening and onto the upper surface of the substrate, removing the stencil, and planarizing an upper surface of the epoxy material to form an epoxy spacer.
