WebRecent joint efforts between FormFactor and industry leaders successfully demonstrated that testing beyond 3 GHz is achievable. The extended capability of FormFactor’s HFTAP K32 probe card solution enables DRAM customers on wafer-level speed testing up to 3.2 GHz/ 6.4 Gbps for next-generation KGD memory. Wafer testing is a step performed during semiconductor device fabrication after BEOL process is finished. During this step, performed before a wafer is sent to die preparation, all individual integrated circuits that are present on the wafer are tested for functional defects by applying special test patterns to them. The wafer testing is performed by a piece of test equipment called a wafer prober. The process of wafer testing can be referred to in several ways: Wafer Final Test …
