Abstract:
Method of exercising semiconductor devices, comprising:fabricating a plurality of resilient interconnection elements directly on a plurality of unsingulated semiconductor dies on a semiconductor wafer each interconnection element having(i) a portion attached to a semiconductor die,(ii) a resilient section, having an elongate springable shape, extending from the portion, and(iii) a contact region remote from the semiconductor die,the interconnection element being free standing and the contact region being depressible towards the semiconductor wafer due to resilient spring action of the resilient section;exercising at least a portion of the unsingulated semiconductor dies by contacting the respective contact regions of at least some of the interconnection elements and electrically accessing the semiconductor dies through the interconnection elements; andthen singulating the semiconductor dies from the semiconductor wafer.
