YIELD ANALYSIS FOR SEMICONDUCTOR …

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 … WebThe traditional process for flip chip test has been to clean the probe card or purchase a card that cost 5 to 10x more than required for the job. By taking the strategy of cleaning the wafers, operational costs can be reduced. Throughput can be improved. And KGD can be increased without the use of ineffective plasma tools.
