Abstract
An integrated substrate for testing a semiconductor wafer and a method are provided. The integrated substrate includes a first redistribution structure including a fine redistribution circuitry, a plurality of testing tips disposed on a first surface of the first redistribution structure and electrically connected to the fine redistribution circuitry to probe the semiconductor wafer, a second redistribution structure including a coarse redistribution circuitry and disposed over a second surface of the first redistribution structure opposite to the first surface, and a plurality of conductive joints interposed between the coarse redistribution circuitry and the fine redistribution circuitry to provide electrical connections therebetween. A layout density of the fine redistribution circuitry is denser than that of the coarse redistribution circuitry.
