Abstract: Microelectronic assemblies, related devices and methods, are disclosed herein. In some embodiments, a microelectronic assembly may include a first die, having a first surface and an opposing second surface; a redistribution layer (RDL) having a surface, wherein the first surface of the first die is on and electrically coupled to the surface of the RDL by non-solder interconnects; and a second die at the second surface of the first die, wherein the second die is electrically coupled directly to the second surface of the first die by solder interconnects.

Abstract: A method for detecting a crack in a semiconductor wafer, which includes an electrical device and a connecting pad electrically coupled with the electrical device, is described. The crack is detected by an acoustic detector being acoustically coupled to the semiconductor wafer during contacting the contacting pad with a probe.

Abstract: A semiconductor device includes a first die, a substrate, and a first interconnect. The first die includes a first isolation region and a first contact at least partially overlapping the first isolation region. The substrate includes a second contact. The first interconnect couples the first contact to the second contact. The first interconnect is defined by a via through the first isolation region.

Abstract: A ceramic substrate secured with a flexible adhesive to a first side of a printed circuit board that belongs to a module and has circuit structures is provided. The ceramic substrate is contacted to the circuit structures with bond connections. The terminal elements are formed by approximately spherical accumulations of solder attached on the backside of the printed circuit board, these solder accumulations being connected to the circuit structures on the first side of the printed circuit board via through-contactings.
