Abstract

A thermal-stress-absorbing interface structure is provided between a semiconductor integrated circuit chip and a surface-mount structure. The interface structure comprises an elongated conductive-bump pad having a first length-wise end and a second length-wise end, and a side. The pad has an interconnection line extending from the side thereof intermediate the first and the second ends. The interconnection line is electrically connected to the chip. The interface structure further includes a first polymer layer having an exposed surface, and a second polymer layer, each having a different modulus of elasticity, disposed below the pad. The second polymer layer extends over substantially the entire exposed surface of the first polymer layer to absorb a thermal stress during thermal cycling.
