Abstract
A device with contact elements. One embodiment provides an electrical device including a structure defining a main face. The structure includes an array of cavities and an array of overhang regions, each overhang region defining an opening to one of the cavities. The electrical device further includes an array of contact elements, each contact element only partially filling one of the cavities and protruding from the structure over the main face.
