Abstract
A device includes a semiconductor chip and a redistribution layer (RDL) structure connected to the semiconductor chip. The redistribution layer structure comprises a first region including: a first bump connected to the semiconductor chip; a second bump; and a plurality of first redistribution layers connected between the first bump and the second bump. The RDL structure includes a second region laterally surrounding the first region, the second region including a plurality of second redistribution layers. The RDL structure includes an isolation region laterally separating the plurality of first redistribution layers from the plurality of second redistribution layer. The isolation region includes at least one region that is straight, continuous, extends from an upper surface of the redistribution layer structure to a lower surface of the first redistribution layer structure, and has at least a selected width.
