the diffraction limitation of processes using optical photons and the technological difficulties connected with x-ray processes, charged particle beams are becoming popular. With them it is possible to write directly on a wafer under computer control, without using a mask. Focused ion beams offer especially g978-1-4612-8247-1978-1-4613-0923-9

Gwo-Ching Wang,Toh-Ming Lue analyzed the operation of the long magnetic lens. We established the fact that a clear image can only be produced if the particles move close to the field lines. Otherwise, different particles will be focused at different points and the image will be blurred.

It is a mistake, however, to take this appellation literally; the applications of the technique transcend chemical analysis, and presentation of even a selected subset of its contributions will require a number of lectures.

Gwo-Ching Wang,Toh-Ming Luwavelength of the scattered wave does not have to be the same as that for the incident plane wave. If it is the same the wave diffraction is said to be elastic, that is no energy transfer takes place between the incident wave and the diffraction object. If the diffracted wave length is different the
