Abstract
A method of making a microelectronic assembly including a compliant interface includes providing a first support structure, such as a flexible dielectric sheet, having a first surface and a porous resilient layer on the first surface of the first support structure, stretching the first support structure and bonding the stretched first support structure to a ring structure. The first surface of a second support structure, such as a semiconductor wafer, is then abutted against the porous layer and, desirably after the abutting step, a first curable liquid is disposed between the first and second support structures and within the porous layer. The first curable liquid may then be at least partially cured.
