IPC: H01L21/329
Filed: 1991-04-19
Abstract: A method of manufacturing a silicon body (5) having an n-type top layer (1') and an adjoining, more highly doped n-type base layer (2'), by which a first, n-type silicon slice (1) and a second, more highly doped n-type silicon slice (2) are put one on the other and then bonded together by heating. To obtain a low contact resistance between top layer (1') and base layer (2'), a boundary layer having a higher doping than the toplayer (1') is provided in the top layer (1') adjoining the base layer (2'). According to the invention, the boundary layer is formed by diffusion of an n-type dopant (11, 14) into the first slice (1) from the second slice (2) during heating. The concentration of the n-type dopant (11, 14) is taken so high in this case that boron (12) present as an impurity is overdoped, so that undesired pn transitions cannot occur. Measures according to the invention present the advantage that pollution of the first slice (1) is counteracted, while in addition the boundary layer is given a steep concentration profile. Semiconductor devices manufactured in body (5) will as a result have a comparatively high switching speed and a comparatively low forward bias.

Abstract: A kneading apparatus is constructed as follows. A plurality of rotatable discs (6,9,11) are mounted on a screw shaft (1a) disposed on a hollow cylinder (1), and a plurality of fixed doughnut members (17,18,21) are mounted on an inner wall of the hollow cylinder.

A screw flight (10A) is mounted helically on the rotatable shaft between two adjacent rotatable discs, and a notch (10B) is formed at a downstream end of the screw flight. The notch serves as a passage for material in an acute corner section defined between the more downstream located rotatable disc of the two adjacent ones and the screw flight. Accordingly, there will be little likelihood that the material is trapped in the acute corner section to form an accumulated mass therein and that old material is mixed into material being fed.

Abstract: A power plant with efficient emission control and high turbine inlet temperatures includes a combustor (30) for the combustion of carbonaceous sulfur-bearing fuel. The combustion of this fuel produces a hot gas with SO x  and NO x  contaminants. This gas is conveyed to a refractory heat exchanger (40) where some of the heat from the gas is transferred to a pressurized air stream. The gas is then conveyed to a fluidized bed reactor (56). The fluidized bed reactor (50) includes a central chamber with a fluidized bed (53) positioned at the base of the chamber. Heat exchangers (62) are positioned within the fluidized bed. These heat exchangers (62) preheat the pressurized air stream which is first conveyed to the refractory heat exchanger 840) and later conveyed to a turbine assembly (22). The fluidized bed reactor (50) also includes circulating particulate matter, such as CaO. Ammonia may also be injected (54) into the fluidized bed reactor (50). When operating at a temperature of at least 1,500°F, the fluidized bed reactor (50) facilitates chemical reactions between the CaO and the SO x  contaminants. The fluidized bed reactor (50) also facilitates chemical reactions between the ammonia and NO x  contaminants. These reactions significantly reduce the contaminants originally found in the hot, dirty gas.
