Research output: Patent


An atomic layer deposition apparatus including an atomic layer deposition reactor and a reactor door. The reactor door is arranged against the end edge of the reactor in a closed position of the reactor. The apparatus having a cooling arrangement for cooling the reactor door having a shell structure surrounding the reactor from the outside of the reactor such that a cooling channel is formed between the shell structure and the at least one side wall of the reactor; a heat exchanger element arranged in the cooling channel in an area of the end edge; and a ventilation discharge connection in connection with the cooling channel provided at a distance from the edge end.
