Abstract

A microelectronic device package includes a microelectronic device, a masking material defined (MMD) contact, and a non-masking material defined (NMMD) contact. The microelectronic device is supported on, and electrically connected to, one of a package substrate and a redistribution layer. The MMD contact is located in a first region of the one of the package substrate and the redistribution layer and facilitates a first electrical connection between the microelectronic device and the one of the package substrate and the redistribution layer. The NMMD contact is located in a second, different region of the one of the package substrate and the redistribution layer and facilitates a second electrical connection between the microelectronic device and the one of the package substrate and the redistribution layer. Related methods and systems are also disclosed.
