Patent JP-H0195452-A (JP)
Title: Ion source device
Inventor: FURUYA MASAYASU
IPC: H01J37/08
Filed: 1987-10-05
Abstract: PURPOSE:To obtain an ion source device of a high ion beam utilization rate by constituting ion guide-out electrodes with a multiplicity of bar-like electrodes running parallel to each other, thereby reducing rate of collision diffusion to charge conversion of an ion beam. CONSTITUTION:Ion guide-out electrodes are constituted with a multiplicity of bar-like electrodes running parallel to each other. Making the direction of the gaps between the bar-like electrodes 5 same with that of the longitudinal direction of a slit, neutral molecules discharged out of an opening 1 may pass through these gaps easily to the back side of the bar-like electrodes 5. This increases the conductance of the neutral molecule flow remarkably, reduces pressures around said opening, remarkably decreases the rate of collision diffusion to charge conversion of an ion beam, and improves ion beam utilization rate. Further, while electric field concentrates on the surface of the bar-like electrodes 5 of the ion guide-out electrodes, the electric field is broardened in the vicinity of the opening of a semi-closed vessel, producing little difference in the ion guide-out effect, with a similar electric field distribution to that of the case in which a plate-like ion guide-out electrode is used.

Abstract: PURPOSE:To reduce strain due to stress applied on a substrate, by providing a substrate-heating device on the upper side of the substrate, using a material having good reflecting efficiency directly below the substrate, arranging a shutter having a concave spherical surface structure, and simultaneously heating the top and back surfaces of the substrate. CONSTITUTION:A substrate 2 is heated with a heater 3 up to a thin-film forming temperature. The back surface of the substrate 2 is heated by the radiated heat of the heater 3. At the same time, the radiated heat is reflected by a metal shutter 4 made of gold, aluminum or the like, which is provided directly below the substrate 2 and has a concave spherical structure and good reflecting efficiency. The heat is reflected to the top surface of the substrate 2, which is the thin-film forming side. The surface is heated to the thin-film forming temperature. After the substrate 2 is heated to the thin-film forming temperature by a magnetic-field generating coil 8, the temperature is kept at this level for a while. An evaporation source 5 is sufficiently fused by the method such as an electron beam or resistor heating. Then, the shutter 4 is opened, and a thin film is grown on the substrate 2. The thin-film forming temperature is set at 200 deg.C. As the evaporation source, Permalloy ingot is used. A Permalloy thin film has been grown by about 300Angstrom  under working pressure of 1X10<-6>Torr.
