Abstract:
Combinatorial synthesis system, comprising:a plurality of targets arranged in a predetermined relationship therebetween, each of said targets being formed of a respective ingredient material; a substrate displaced from said targets by a variably controlled distance, a plurality of deposition centers being defined at predetermined locations on said substrate circumferentially spaced apart each from the other, each of said depositions centers being in correspondence to a respective one of said targets, said substrate being rotatable about a central axis; a focused energetic beam directed towards one of said targets and ejecting particulates of the ingredient material of said one of said targets, said ejected particulates being deposited at a respective one of said deposition centers corresponding to said one of said targets and at a distributed deposition area around said respective one of each said deposition centers, said distributed deposition area of said deposition centers on said substrate overlapping each with respect to the other; and, control means for sequentially controlling mutual disposition between said energetic beam and each of said targets, thereby coating said substrate with a deposition film having a continuously varying composition of the ingredient materials of said targets substantially at said distributed deposition areas between said deposition centers.
