ABSTRACT:
A pair of substrates is mounted with first faces thereof directed away from each other and second faces thereof in sealing contact with each other. The substrates are then immersed in a first molten flux for depositing a film of a first material on the first faces of each of the substrates by liquid phase epitaxy (LPE). During the immersion in the first molten flux, the second faces of the substrates, being clamped against each other, seal each other from contact with the flux. After removal from the first flux, the pair of substrates is mounted with the films on the first faces thereof in sealing contact with each other. The substrates are then immersed in a second molten flux for depositing a film of a second material on the second faces of each of the substrates by LPE. The second material is, typically, different from the first material. During the immersion in the second molten flux, the films on the first faces of the substrates, being clamped against each other, seal each other from contact with the flux.
