A semiconductor device includes a plurality of functional element chips, an electric connection member joined to two of the functional element chips, a first wire and a resin configured to cover the functional element chips, the electric connection member and the first wire. One of the two functional element chips may be a first semiconductor chip having first and second major surface electrodes facing toward the same direction and a first rear surface electrode facing in a direction opposite to a direction in which the first major surface electrode faces. The electric connection member may be joined to the first major surface electrode. The first wire may be joined to the second major surface electrode. The first wire may include a portion overlapping with the electric connection member in a thickness direction of the first semiconductor chip.

A semiconductor assembly with a package on package (POP) structure includes a first semiconductor package having a first lower substrate, a first upper substrate facing the first lower substrate, and a first semiconductor chip mounted on an area of the first lower substrate. The POP structure further includes a second semiconductor package having a second lower substrate stacked on the first semiconductor package and spaced apart from the first semiconductor package, and a second semiconductor chip mounted in an area of the second lower substrate. At least one passive element is disposed in one of the first upper substrate and the second lower substrate and electrically connected to the second semiconductor chip.

Examples herein describe a die that includes a testing system (e.g., testing circuitry) for measuring the actual resistance of on-die resistors. When testing the die, an I/O element (e.g., a solder bump) can be used to sweep a voltage across the on-die resistor. The testing system identifies when the voltage across the on-die resistor reaches a predefined reference voltage and measures the corresponding current. Using the measured current and the reference voltage, the testing system can identify the actual resistance of the on-die resistor. In one embodiment, the on-die resistor is tunable such if the on-die resistor has a divergent value, the die can adjust its resistance value to the desired value.

An adhesion layer may be formed over portions of a redistribution layer (RDL) in a redistribution structure of a semiconductor device package. The portions of the RDL over which the adhesion layer is formed may be located in the shadow of (e.g., the areas under and/or over and within the perimeter of) one or more TIVs that are connected with the redistribution layer structure. The adhesion layer, along with a seed layer on which the portions of the RDL are formed, encapsulate the portions of the RDL in the shadow of the one or more TIVs, which promotes and/or increases adhesion between the portions of the RDL and the polymer layers of the redistribution structure.

A package for power electronics includes a power substrate, a number of power semiconductor die, and a Kelvin connection contact. Each one of the power semiconductor die are on the power substrate and include a first power switching pad, a second power switching pad, a control pad, a semiconductor structure, and a Kelvin connection pad. The semiconductor structure is between the first power switching pad, the second power switching pad, and the control pad, and is configured such that a resistance of a power switching path between the first power switching pad and the second power switching pad is based on a control signal provided at the control pad. The Kelvin connection pad is coupled to the power switching path. The Kelvin connection contact is coupled to the Kelvin connection pad of each one of the power semiconductor die via a Kelvin conductive trace on the power substrate.

Aspects disclosed herein include integrated circuit (IC) packages employing a capacitor interposer substrate with aligned external interconnects, and related fabrication methods. The IC package includes one or more semiconductor dies (dies) electrically coupled to a package substrate that supports electrical signal routing to and from the die(s). The capacitor interposer substrate is disposed between the die(s) and the package substrate. The die(s) is coupled to embedded capacitor(s) in the capacitor interposer substrate through die interconnects coupled to external interconnects of the capacitor interposer substrate. In exemplary aspects, the external interconnects on the outer surfaces of the capacitor interposer substrate are aligned. In this manner, the capacitor interposer substrate can maintain interconnect compatibility to the die(s) and package substrate if the die(s) and package substrate have a pattern of die interconnects and external interconnects that are designed to align with each other when coupled to each other.
