Abstract
A method for selectively marking integrated circuit chips (205, 210) formed on a wafer (200) includes the steps of testing the integrated circuit chips (205, 210)) of the wafer (200) to determine whether the integrated circuit chips (205, 210) are functional, dispensing underfill material (215) only on functional integrated circuit chips (205), and separating, subsequent to the dispensing step, the wafer (200) into individual integrated circuit chips (205, 210). The functional integrated circuit chips (205) are marked with the underfill material (215), while nonfunctional integrated circuit chips (210) are not marked with the underfill material (215).
