Wafer-level test and burn-in is the process of subjecting semiconductor devices to electrical testing and burn-in, while the devices are still in wafer form. The burn-in is the temperature reliability stress test, which is used in detecting and screening out the potential early failures. Wafer-level test and burn-in is applicable to devices sold as a bare die, wafer level packaged devices, and devices that are intended for conventional packaging. In the last application, wafer-level test and burn-in is performed as a prescreen, so the parts that are passed can undergo backend processing. According to experts, the wafer level burn-in technology lowers the chip manufacturing costs by 15% and shortens the product lifecycle by 25%. The semiconductor industry has evolved significantly in the past 10 years, in terms of both technological advancements and changes to the industry’s value chain. As electronic gate sizes and other feature dimensions grow smaller and wafer sizes continue to increase, the cost of developing these technologies is also growing. Companies have to invest significantly more money in research and development each year in order to work on a competitive scale. These technological hurdles and the costs that accompany them have led to a restructuring of the industry value chain.
The advantages of the wafer-level test and burn-in process such as low cost, reliability, and simplicity have increased the attractiveness of wafer-level burn-in the market. In addition, the wafer-level and burn-in technology requires a single alignment step and a single dimensionally stable fixture to burn in hundreds of ICs simultaneously. This approach is much cheaper than using hundreds of precision die carriers. Additionally, other benefits include reduction in process steps when compared to packaged level and die level burn-in, reduction of wafer test insertion and probe time, and faster test result feedback to the fab. These benefits over other methods such as die level burn-in is fueling the market growth. Semiconductors are increasingly used in electronic systems and parts of automobiles such as infotainment, engine control, and safety features. Compound semiconductors, which are used in autonomous and self-driving cars require 100% burn-in due to natural material properties.
