As a continued effort to improve the performance of low energy scannin
g electron probe systems for application in microscopy, lithography, m
etrology, etc., miniaturized electron beam columns, approximately 3 mm
in length, demonstrating a probe size of 10 nm with a beam current of
greater than or equal to 1 nA at 1 keV, have been successfully develo
ped. This paper presents current status, future directions and potenti
al applications of these microcolumns.
