Title: Charged particle ray generator
Inventor: AIHARA RYUZO
IPC: H01J37/08
Filed: 1985-04-10
Abstract: PURPOSE:To reduce by half the voltage applied to a filter capacitor and to make a charged particle ray generator compact, by causing an electrical current, which takes place at the time of discharge between a positive and a negative electrodes and is inverse in direction to a charging current, to flow through a residual resistance from a diodes so as to be consumed. CONSTITUTION:A series circuit of diodes Df1, Df2 is connected in parallel with a series circuit of filter capacitors Cf1, Cf2 to a cockcroft-Walton circuit 1. The diodesd Df1, Df2 are connected to each other in such a manner that their forward direction is inverse to the direction of a charging current caused to flow through the filter capacitors Cf1, Cf2 by the Cockcroft-Walton circuit 1. As a result, an electrical current flows through a closed circuit U as shown by a full line (i), and the voltage V across the filter capacitors Cf1, Cf2 changes as shown by a full line V. The range of the change in the voltage V is thus reduced by half in comparison with a conventional art so that though discharge takes place between a positive electrode 2a and a negative electrode 2b, the dielectric strength of the filter capacitors Cf1, Cf2 does not need to be higher than a voltage V0. For that reason, the filter capacitors Cf1, Cf2 can be made compact.

Abstract: PURPOSE:To make it possible to perform effective bonding, by bonding a single crystal silicon substrate and an insulating substrate by diffusing bonding in a vacuum, in which heating and compressing are carried out, and thereafter performing etching and polishing of the silicon single crystal. CONSTITUTION:An insulating substrate 1 comprising quartz or silicon nitride and a silicon single crystal 2 are held by a ceramic jig 3. After a parting agent is applied, compression of about 0.5kg/mm is performed in a vacuum atmosphere of about 10Torr in a diffusion bonding apparatus 10 at a temperature of about 1,300 deg.C. Thus the insulating substrate 1 and the silicon single crystal 2 are bonded. At this time, positive bonding reaction occurs. Atoms are mutually diffused between the substrate materials such as the silicon nitride and the silicon single crystal, and powerful bonding is carried out at the atomic level. Thus, a semiconductor substrate raw material 5 is manufactured. Then, the side of the insulating substrate is protected by a resin 6 such as wax. Etching is performed until the thickness of the single crystal silicon 2 becomes several mum - several tens of mum. Thereafter, an etched surface 7 is precisely polished into a mirror state and the semiconductor substrate is obtained.
