Abstract
A semiconductor manufacturing method includes forming a first redistribution structure with a fine redistribution circuitry over a first temporary carrier; forming testing tips on a first surface of the fine redistribution circuitry; transferring the testing tips and the first redistribution structure to a second temporary carrier provided with a temporary adhesive layer, where the testing tips are embedded in the temporary adhesive layer with the second temporary carrier disposed on the temporary adhesive layer; releasing the first temporary carrier to expose a second surface of the fine redistribution circuitry; coupling a second redistribution structure with a coarse redistribution circuitry to the first redistribution structure through conductive joints, where the conductive joints are formed on the second surface of the fine redistribution circuitry; and releasing the second temporary carrier and the temporary adhesive layer from the testing tips and the first redistribution structure after coupling the second redistribution structure.
