Abstract:
1. A deposition system, comprising: a wafer receiving unit configured for receiving a wafer; a deposition unit; and a control unit configured to control the deposition unit so as to deposit a material layer on the wafer received in the wafer receiving unit by a deposition process, wherein said deposition process has at least two sub-processes comprising a deposition sub-process wherein material is deposited on a wafer and a removal sub-process wherein part of said deposited material is removed from said wafer following the deposition sub-process, and said control unit is configured for generating a deposition time for the removal sub-process based on at least one previous value of an effective deposition rate for the removal sub-process and a target thickness of the material following the deposition sub-process and the removal sub-process.
