Abstract
Abstract A growth apparatus for a liquid growth multi-layer film, in which a growth substrate is housed in a hollow of a first supporter, in which a plurality of molten liquids are respectively provided in a plurality of hollows arranged in regular spaces on one surface of a second supporter, and in which one of the first supporter and the second supporter is moved with respect to the other in opposing the growth substrate with the molten liquids. In accordance with the present invention, the growth substrate provided in the first supporter is shifted closely to and at the upper side of the molten liquids, and the second supporter is provided with a plurality of small hollows each at a space between adjacent hollows of the second supporter.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
194 words
A growth apparatus for a liquid growth multi-layer film, comprising: a first supporter having a downwardly facing hollow housing a growth substrate, the substrate face on which the film is to be grown lying substantially in the face plane of said supporter, and said face plane terminating in sharply defined edges; a second supporter having in the upwardly facing surface thereof a plurality of longitudinally spaced and aligned, second hollows, the first and alternate hollows therefrom containing separate ones of a plurality of molten liquids from which said multi-layer film is to be grown and the remaining hollows being void; said first supporter overlying, and in longitudinal alignment with, said second supporter and said face plane closely adjacent said surface; said supporters being configured to include guide structure whereby to maintain and fix the described spatial relationship of the supporters when assembled; and means for longitudinally moving said supporters relative one another whereby one of said defined edges sequentially skims off the exposed face of each of said molten liquids, each removed liquid being received in the next adjacent void hollow, and the substrate sequentially contacting each skimmed molten liquid to effect said growth.
Claim 2
Dependent Claim
194 words
A growth apparatus for a liquid growth multi-layer film, comprising: a first supporter having a downwardly facing hollow housing a growth substrate, the substrate face on which the film is to be grown lying substantially in the face plane of said supporter, and said face plane terminating in sharply defined edges; a second supporter having in the upwardly facing surface thereof a plurality of longitudinally spaced and aligned, second hollows, the first and alternate hollows therefrom containing separate ones of a plurality of molten liquids from which said multi-layer film is to be grown and the remaining hollows being void; said first supporter overlying, and in longitudinal alignment with, said second supporter and said face plane closely adjacent said surface; said supporters being configured to include guide structure whereby to maintain and fix the described spatial relationship of the supporters when assembled; and means for longitudinally moving said supporters relative one another whereby one of said defined edges sequentially skims off the exposed face of each of said molten liquids, each removed liquid being received in the next adjacent void hollow, and the substrate sequentially contacting each skimmed molten liquid to effect said growth.
Claim 3
Dependent Claim
52 words
A growth apparatus according to claim 1, whereby said configuration the first supporter is slidably coupled with a straight groove provided at the upper side of the second supporter, and the first supporter has a pair of straight projections which are coupled with a pair of small grooves in the straight groove.
Claim 4
Dependent Claim
29 words
A growth apparatus according to claim 1, whereby said configuration the first supporter is in the form of a vertically oriented annulus and the second supporter is slidable therethrough.
