Abstract
An apparatus for depositing a material by evaporation on a substrate having a large surface. The apparatus includes an enclosure in which are placed a number of material evaporation sources. It also includes a device for channeling or piping of vapors emitted by the sources toward the substrate during evaporation. This is formed by walls or covers which define compartments within the enclosure, each evaporation source being placed in a compartment. The apparatus can also utilize a device for moving the substrate in order to improve the uniformity of the deposit.
