2.95 Abstract With the rapid development of the IC manufacture, the critical dimension(CD) of the manufacturable CMOS technology has been put into 90nm, even 65nm and below from 130nm.
1.The setup and hold times, why are they even there? How can we find out how high they are? The logic gates are nowadays built most of the time, again, in so-called CMOS technology.
2.The purpose of having two systems is that the phosphorescent screen and camera is used to ensure that the electron beam and magnetic lenses are set up properly, as an incorrectly focused beam could damage the sensitive CMOS camera.
3.When you're ready to capture a high-resolution image, the phosphorescent screen moves out of the way, and the image is captured using the second system with a more sensitive CMOS camera that has a higher resolution and dynamic range.
