Abstract

Apparatuses and methods for coupling semiconductor devices are disclosed. Terminals (e.g., die pads) of a plurality of semiconductor devices may be coupled in a daisy chain manner through conductive structures that couple one or more terminals of a semiconductor device to two conductive bond pads. The conductive structures may be included in a redistribution layer (RDL) structure. The RDL structure may have a “U” shape in some embodiments of the disclosure. Each end of the “U” shape may be coupled to a respective one of the two conductive bond pads, and the terminal of the semiconductor device may be coupled to the RDL structure. The conductive bond pads of a semiconductor device may be coupled to conductive bond pads of other semiconductor devices by conductors (e.g., bond wires). As a result, the terminals of the semiconductor devices may be coupled in a daisy chain manner through the RDL structures, conductive bond pads, and conductors.
