A new beam deflection‐chopping system has been developed which circumvents the limitation of electron pulse generation at maximum repetition rates of a few GHz with low energy beams using conventional deflection‐chopping techniques. In an electro

The influence of fifth‐order deflection aberrations for purely magnetic post lens single‐deflection systems has been investigated. A regrouping of the large numbers of third‐ and fifth‐order aberration coefficients has been performed to reduc

Computer-aided design techniques are now used extensively for the production of masks in the microelectronic industries. In these methods the microcircuit patterns are broken down into simpler component parts, such as rectangles, whose co-ordinates a

In the transmission electron microscope, as shown in figure 1 (Nixon 1962), the electron gun at the top illuminates the specimen with the beam angle controlled by the condenser lens. The lenses below the specimen are used to magnify the image of the

The X-ray shadow projection microscope has been limited previously to a resolution of 0$\cdot $5 $\mu $. A resolution of 0$\cdot $1 $\mu $ has now been achieved with the same exposure time of 5 min. This has been done by using a very thin gold-leaf X

Direct metallic deposition exploits the advantages of electron-beam exposure for the production of fine structures and avoids the use of resists and chemical etching. The process involves the electron-induced decomposition of metallic compounds in ar
