WebThere are several types of ultrasound imaging techniques. As the most common type, the 2-D ultrasound provides a flat picture of one aspect of the baby. If more information is needed, a 3-D ultrasound exam can be done. This technique, which provides a 3-D picture, requires a special machine and special training. Websize in required defect measurement is getting smaller year by year, and detection and analysis of defects are getting even tougher. Concerning the defect-analysis method used for test wafers, analyses of wafer-transport particle and process-generated particle are carried out.
