Title: Silicon nitride-based composite sintered body
Inventor: MATSUI TATSUTAMA
IPC: C04B35/626
Filed: 1990-11-30
Abstract: PURPOSE:To simultaneously enhance strength and toughness by dispersing particles of nm order having a high coefft. of thermal expansion in silicon nitride grains and a grain boundary phase. CONSTITUTION:Particles having 1-500nm average particle diameter and >=5X10<-6>/ deg.C coefft. of thermal expansion are dispersed in silicon nitride and/or sialon grains having 0.05-3mum average minor axis size and <=10 aspect ratio and in a grain boundary phase. The resulting composite powder is press-molded and sintered to obtain a composite sintered body. By this method, residual compressive stress is produced in the silicon nitride grains by the difference in coefft. of thermal expansion at the time of cooling from the sintering temp. to room temp. Since this stress field is applied to the tips of cracks at the time of fracture, resistance to the occurrence and propagation of cracks is increased, fracture toughness is enhanced and strength and toughness are enhanced.

IPC: H01J37/317
Filed: 1991-12-16
Abstract: PURPOSE:To effect uniform ion implantation over a wide area through scan made by beams from a compact-sized ion source and after selection of a desired ion kind. CONSTITUTION:Substantially parallel beams each having a slit configuration in section are drawn out from an ion source 1 by the use of a draw-out voltage and an acceleration voltage. The beams are caused to pass through a fixed magnetic field of a sector magnet 3 for conducting mass analysis. A difference is exhibited in movement quantity according to the ion kind, and as a result, different locuses of movement are described. By this, a desired kind of ion is selected and in subsequence unnecessary ion kinds are eliminated by an analyzing slit 4. The desired kinds of ions pass through the slit 4 and are incident upon a sextet pole magnetic lens 5 for re-shaping. Subsequently, the desired kind of ions transit through a drift space to reach the surface of a substrate 9, and are irradiated thereupon in the form of a horizontally elongate slit. On the other hand, the ion source 1 has its ion draw-out port swung by a drive means 2 in the vertical direction, so that the substrate 9 surface is uniformly scanned by the ion beams. This enables uniform ion implantation.
