Electron beam technology - SEM to microcolumn

View publication


As a continued effort to improve the performance of low energy scanning electron probe systems for application in microscopy, lithography, metrology, etc., miniaturized electron beam columns, approximately 3 mm in length, demonstrating a probe size of 10 nm with a beam current of ≥ 1 n A at 1 keV, have been successfully developed. This paper presents current status, future directions and potential applications of these microcolumns.
