Title: Silicon@ substrate mfr. for DRAM components - comprises forming silicon@ mirror wafer and subjecting it to two=stage heat treatment process, then removing surface layer
Inventor: AKIYAMA NOBUYUKI
IPC: C30B33/00
Filed: 1991-03-15
Abstract: A process is disclosed for mfg. a silicon substrate for a semiconductor device, in which a silicon mirror wafer is formed and subjected to a two-stage heat treatment process, involving firstly a high temp. and secondly a lower temp.. A surface layer of the silicon mirror wafer is removed after carrying out the two-stage heat treatment procedure. A layer which is 0.2-20 microns thick is removed from the surface of the wafer.

Title: Procedure for separation of flow of heterogeneous materials
Inventor: CERRONI MANLIO
IPC: B07B13/10
Filed: 1991-07-30
Abstract: The procedure involves throwing a flow of heterogenous material against a surface, and making it fall to a mobile collector. The trajectories of fall is made different by the dynamics of impact, according to the rigidity of the material, with a consequent division of the original material into two separate flows.     The flow of material to be treated undergoes three successive phases of treatment. A first "launch" phase, with a consequent impact against a wall, during which the dynamics of impact differ according to the rigidity of the material. A second phase in which regulated current of air passes across the trajectory of fall. A third phase, in which an inclined plane moves in a predetermined direction.
