Abstract:
1. A structure comprising: a substrate having first and second oppositely facing surfaces, a plurality of electrically conductive elements at the first surface, and a plurality of first terminals at the second surface configured for connection to a first component, at least some of the first terminals electrically connected with the conductive elements; a spacer element overlying a first portion of the first surface, the spacer element having a third surface facing away from the first surface and an edge surface extending from the third surface towards the first surface; a plurality of second terminals overlying the third surface and overlying the first surface, the second terminals configured for connection to a second component; and a plurality of traces electrically coupled between the second terminals and at least one of the electrically conductive elements or the first terminals, the traces extending from the second terminals along the edge surface, wherein the spacer element at least partially defines a second portion of the first surface, the second portion being other than the first portion of the first surface and having an area sized to accommodate an entire area of a microelectronic element, and at least some of the conductive elements at the first surface are at the second portion and configured to permit connection with such microelectronic element.
