Title: Substrate treating system and substrate transporting method
Inventor: KUWABARA JOJI
IPC: H01L21/677
Filed: 2019-07-19
Abstract: To provide a substrate treating system and a substrate transporting method capable of suppressing reduction in throughput.SOLUTION: For instance, it is assumed that an ID block, a first treating block, and a second treating block are arranged in this order. In this case, for transporting a substrate treated in the second treating block to an indexer block, the substrate is necessarily sent through the first treating block without any treatment by the first treating block. However, the first treating block 3 and the second treating block 5 are also connected to the indexer block 2. Therefore, transportation of the substrate W is performable directly from the second treating block 5 to the indexer block 2 without intervening the first treating block 3. Therefore, reduction in throughput can be suppressed.SELECTED DRAWING: Figure 1
