摘要:
Methods and apparatuses for wafer level packaging (WLP) semiconductor devices are disclosed. A redistribution layer (RDL) is formed on a first passivation layer in contact with a conductive pad over a surface of a die. The RDL layer is on top of a first region of the first passivation layer. A second passivation layer is formed on the RDL layer with an opening to expose the RDL layer, and over the first passivation layer. An under bump metallization (UBM) layer is formed over the second passivation layer in contact with the exposed RDL layer. A second region of the first passivation layer disjoint from the first region is determined by projecting an outer periphery of a solder ball or other connector onto the surface.

A chip scale semiconductor device comprises a semiconductor die, a first bump and a second bump. The first bump having a first diameter and a first height is formed on an outer region of the semiconductor die. A second bump having a second diameter and a second height is formed on an inner region of the semiconductor die. The second diameter is greater than the first diameter while the second height is the same as the first height. By changing the shape of the bump, the stress and strain can be redistributed through the bump. As a result, the thermal cycling reliability of the chip scale semiconductor device is improved.
