    • An evaporation cell for evaporating a material onto a substrate placed in a vacuum deposition chamber, includes an inner enclosure delimiting an evaporation chamber for receiving a crucible containing the material and having an opening for inserting the crucible into the evaporation chamber; evaporation elements placed at the periphery of the inner enclosure for placing the crucible in evaporation conditions; an injection duct for transporting a flow of vapour of the evaporated material from the evaporation chamber to an injector located in the vacuum deposition chamber; and a stop valve placed on the injection duct. The evaporation cell includes insertion opening/shutting elements that have an open configuration for inserting the crucible into the evaporation chamber, and a closed configuration for confining the evaporation chamber in communication with the vacuum deposition chamber via the injection duct, and opening elements to provide an evaporation opening in an envelope of the crucible.

    • A thermal evaporation source includes: a crucible configured to contain a volume of evaporant and a vapor space above the evaporant; a manifold body having within it a hollow expansion chamber that is flowably connected to the vapor space via one or more restriction orifices; one or more effusion nozzles flowably connected to the expansion chamber and exiting an outer surface of the thermal evaporation source, the nozzle(s) oriented to direct an evaporant vapor flow out of the source vertically downward, in one or more horizontal directions, or in one or more directions intermediate between horizontal and vertically downward; and a heater capable of heating some or all of the thermal evaporation source to a temperature sufficient to produce the one or more evaporant vapor flows when a vacuum is applied to the thermal evaporation source.
    • 热蒸发源包括:坩埚,其构造成容纳蒸发剂的体积和蒸发器上方的蒸汽空间; 歧管主体,在其内部具有中空膨胀室,其经由一个或多个限制孔流动地连接到蒸气空间; 一个或多个渗出喷嘴可流动地连接到膨胀室并离开热蒸发源的外表面,喷嘴被定向成将蒸发蒸气流沿垂直向下的一个或多个水平方向引导出源,或者在 在水平和垂直向下之间中间的一个或多个方向; 以及当将真空加到热蒸发源上时能够将部分或全部热蒸发源加热到足以产生一个或多个蒸发蒸气流的温度的加热器。
