Abstract
A method of forming, by melt-spinning techniques, a laminated ribbon structure consisting, for example, of a semiconductor disposed on a metal ribbon substrate. The substrate may be 10-100 .mu.m thick and the semiconductor may be 10-100 .mu.m thick, for example; typically the ribbon width is about one millimeter to several centimeters.
Claims28
A method of forming a multi-layered solid structure by means of rapid quenching of separate melts, that comprises depositing a first melt in the form of a liquid stream from a first delivery orifice upon a fast moving heat extracting surface to effect quenching and solidification thereon and form a first solid layer in ribbon form;
- and simultaneously depositing a second melt in the form of a liquid stream from a second delivery orifice which is physically separated by a small distance from the first orifice in the direction of movement of the first solid layer upon said first solid layer to effect quenching of the second melt and form a second solid layer upon the first solid layer to provide a multi-layered solid structure.
A method of forming a ribbon structure by rapid solidification of a melt, that comprises depositing a first melt in the form of a first liquid stream upon a fast moving surface to form thereon a first layer, depositing a second melt in the form of a second liquid stream spaced from the first liquid stream upon the first layer, and extracting heat from the second melt to quickly form a solid layer formed from said second melt.
A method of forming a ribbon structure, that comprises forming a first melt into a first coherent liquid stream, effecting relative motion between the first coherent liquid stream and a heat exchange surface, depositing the first liquid stream on the heat exchange surface, where it forms a first layer, simultaneously forming a second melt into a second coherent liquid stream, effecting relative motion between the second liquid stream and the first layer, and simultaneously depositing the second liquid stream on the first layer, which second liquid stream quickly solidifies to form a solid layer.
A method of forming a ribbon structure, that comprises forming a first melt into a first liquid stream of molten material, depositing the first stream of molten material upon a moving heat extracting surface to form a first layer on the moving heat extracting surface to move therewith, simultaneously forming a second melt into a second liquid stream of molten material, simultaneously depositing the second stream of molten material upon the moving first layer to effect quenching of the second liquid stream of molten material and form a solid layer therefrom upon said first layer to move therewith.
A method of forming a laminated multi-layered ribbon structure for use in electrical circuitry that comprises forming several melts into several liquid streams of molten materials, the several liquid streams of molten material thus formed being spaced from one another, but being closely spaced, depositing one of the several liquid streams of molten material upon a moving heat exchange surface to form a first layer thereon, and simultaneously in time depositing another of the several liquid streams of molten material upon the first layer to effect quenching thereof to form a solid layer, and depositing other and further liquid streams of molten material successively on the solid layer thus formed to be quenched and form further successive, solid layers into a laminated multi-layered ribbon structure.
