Now it was very difficult to do failure analysis (FA) from front side with multi-metal layers and scaling down. So, OBIRCH & EMMI analysis from backside was studied in microelectronics yield in recent years. As is known to all, we could capture clearer infrared (IR) image from backside as Si substrate was thinner. But if we needed higher resolution image with conventional optical objective lens,...
Delay variation can be very difficult to localize in function failure analysis. In this paper we combine Delay Variation Mapping (DVM) and Soft Defect Localization (SDL) to develop a novel and low-cost method that can detect delay variation effectively. It just uses Static Thermal Laser Stimulation (S-TLS), Oscilloscope and Function Generator to compose a dynamic thermal laser stimulation (D-TLS)...
The characteristics and the working principle of charge coupled device (CCD) are expatiated, and the light source adapting to CCD and the matching relation between the light source and the illumination are analyzed. On this basis, the optical system with lasers, lenses, filters, apertures and other optical devices is designed to adapt to CCD, and the driving timing and the binarization processing...
A variable-focus liquid lens based on EWOD (electrowetting on dielectric) has been developed. It comprises a top glass plate, a ground-electrode-involved bottom glass plate and a counter-electrode-involved cylindrical glass housing which contains two immiscible fluids of air and water with different refractive indices. By changing the applied voltage across the electrodes, we can tune the meniscus...
