Abstract
As the latest integrated circuit designs move toward submicron feature dimensions, optical microscopes commmonly used for critical dimension (CD) measurements no longer have sufficient resolution. 1,2 Just as the semiconductor industry has turned to electron beam lithography for mask making and direct writing to achieve submicron dimensions in VLSI and VHSIC devices, so too must it turn to electron beam instruments to measure these devices. A computer based system for digitally controlling a scanning electron microscope (SEM) is described and its ability to provide precise, accurate measurements evaluated.
