Once the front-end process has been completed, the semiconductor devices or chips are subjected to a variety of electrical tests to determine if they function properly. The percent of devices on the wafer found to perform properly is referred to as the yield. Manufacturers are typically secretive about their yields, but it can be as low as 30%, meaning that only 30% of the chips on the wafer work as intended. Process variation is one among many reasons for low yield… WebJan 1, 2009 · the chip assembly in the conventional process, in a no-flow underfill . process, the underfill is dispensed onto the substrate before the . placement of the chip.
