Patent ID: 8282334

Claim:
An atomic layer deposition (ALD) reactor system comprising: a plurality of vertical flow ALD reactors placed in a pattern in relation to each other, each ALD reactor being configured to receive a batch of substrates for ALD processing, each ALD reactor comprising a lid system having a vacuum chamber lid and a reaction chamber lid, and a vacuum chamber accommodating a reaction chamber accessible from the top for loading of the substrates; and a loading robot comprising a gripping part and a motion arrangement, the loading robot being configured to perform a plurality of loading sequences for loading the reaction chamber of each of said plurality of ALD reactors from the top of the reaction chamber, each loading sequence comprising: raising the lid system into an upper position; picking up with said gripping part a substrate holder carrying a batch of substrates in a storage area or shelf; and moving with said moving arrangement said substrate holder with said batch of substrates into the reaction chamber without passing a separate loading chamber, from the top of the reaction chamber, of the ALD reactor in question.
