Ion implantation beam current

Webcorrespond to an ion implantation of Argon, with a beam current of 100 A, initial energy of 15 keV. The area of scan (x and y) is 5x7 cm 2, and the scan x corresponds to the rotational steps of the target. We made four experimental test: (1) with the target at 10 kV and the electrostatic lens with 0 kV (Figure 3a); (2) with the WebUI-5000, a high-current oxygen ion implanter for SIMOX. Its basic design concepts are the use of a microwave ion source and a mechanical scanning scheme. The implanter has already been applied to SIMOX wafer production and has shown good performance — it has an implant current of 70 mA

WebExperimental research on ion implantation began in the early sixties, with accelerators previously used in nuclear physics. It is worthwhile mentioning here that the experiments thus started with implantations at high energies. The major drawback of these machines, however, was the low beam-current. Another severe problem at that time (1965 ... WebIn order to obtain an ion beam profile, two signals are required, one proportional to the beam width (x-axes) and another proportional to the beam current (y-axes).The beam current can be defined as 47 A Beam V I M : (1) Therefore, an optic-fiber based circuit was developed to send the beam current signal to the ground potential.
