发明名称 Microelectronic elements with compliant terminal mountings and methods for making the same
摘要 A dielectric structure is formed by a molding process, so that a first surface of a dielectric structure is shaped by contact with the mold. The opposite second surface of the dielectric structure is applied onto the front surface of a wafer element. The dielectric layer may include protruding bumps and terminals may be formed on the bumps. The bumps may be of a precise height. The terminals lie at a precisely controlled height above the front surface of the wafer element. The terminals may include projecting posts which extend above a surrounding solder mask layer to facilitate engagement with a test fixture. The posts are immersed within solder joints when the structure is bonded to a circuit panel.
