| Appl. No: | 10/726920 |
| Application Filed: | December 02, 2003 |
| مستخلص: | Provided is a substrate processing apparatus that can reduce power consumption, while maintaining throughput. In addition to a normal mode in which all units are activated, the apparatus is provided with an energy saving mode that is selectable. When the energy saving mode is selected, only essential units that are requisites for a substrate processing are activated and used in the substrate processing. If it is necessary to increase process efficiency, any additional unit may be activated and used in the processing. During standby, only an essential unit can be activated and the rest is halted, or alternatively, all units may be halted. The transition to the energy saving mode can occur when the standby state continues for a predetermined period of time after the normal mode is selected. |

| Claim: | 1. A substrate processing apparatus comprising: (a) at least one processing part each having a plurality of processing elements, processing types of which are the same in each of said at least one processing part; (b) a control element for controlling the operation of said plurality of processing elements, wherein the activation and halt of said processing elements are controlled independently; and (c) a storage element for storing data related to operation conditions of said processing elements, said substrate processing apparatus being not only capable of executing a predetermined substrate processing with all of said plurality of processing elements but also capable of executing said predetermined substrate processing with only part of said plurality of processing elements. |
| Claim: | 2. The substrate processing apparatus according to claim 1 wherein said storage element stores information for specifying at least one first processing element among said plurality of processing elements, wherein said at least one first processing element is previously selected to be activated preferentially in said substrate processing apparatus. |
| Claim: | 3. The substrate processing apparatus according to claim 2 wherein said control element activates said at least one first processing element when no processing element has been activated for execution of said predetermined substrate processing. |
| Claim: | 4. The substrate processing apparatus according to claim 3 further comprising: (d) a selecting element for an operator to select an operation mode from a first mode and a second mode, wherein said first mode is an operation mode in which only said at least one first processing element among said plurality of processing elements is activated at the execution of said predetermined substrate processing, said second mode is an operation mode in which all processing elements are activated at the execution of said predetermined substrate processing, and said control element activates one or more processing elements in accordance with the operation mode selected. |
| Claim: | 5. The substrate processing apparatus according to claim 4 wherein said control element halts one or more objective processing elements having been used for said predetermined substrate processing after a predetermined time has elapsed since operation of said one or more objective processing elements for said predetermined substrate processing had completed. |
| Claim: | 6. The substrate processing apparatus according to claim 5 wherein said one or more objective processing elements are processing element(s) other than said at least one first processing element. |
| Claim: | 7. The substrate processing apparatus according to claim 6 wherein said storage element further stores information specifying at least one second processing element which is previously selected to be optionally activated, and said at least one second processing element is operable to be additionally activated to be used for said predetermined substrate processing when only said at least one first processing element is initially used for said predetermined substrate processing. |
| Claim: | 8. The substrate processing apparatus according to claim 7 wherein said control element halts processing elements other than said at least one first processing element at the termination of said predetermined substrate processing. |
| Claim: | 9. The substrate processing apparatus according to claim 7 wherein said control element halts all of said processing elements in response to termination of said predetermined substrate processing, and said at least one first processing element is activated again when a succeeding substrate processing is executed. |
| Claim: | 10. A method of operating a substrate processing apparatus provided with at least one processing part, said at least one processing part each having a plurality of processing elements, processing types of which are the same in each of said at least one of processing part and activation and halt of which are independently controllable, said method comprising the steps of: (a) storing condition data related to respective operation conditions of said plurality of processing elements; (b) determining whether or not all of said plurality of processing elements is required for a predetermined substrate processing requested; and (c) activating all of said plurality of processing elements or only part of said plurality of processing elements in accordance with the determination result of the step (b) to execute said predetermined substrate processing with reference to said condition data. |
| Claim: | 11. The method according to claim 10 wherein said step (a) comprises the step of (a-1) selecting at least one first processing element which is to be activated preferentially, and (a-2) storing information specifying said first processing element. |
| Claim: | 12. The method according to claim 11 wherein said step (c) comprises the step of (c-1) activating said at least one first processing element when no processing element has been activated for execution of said predetermined substrate processing. |
| Claim: | 13. The method according to claim 12 wherein said step (b) comprises the step of (d-1) determining an operation mode in response to selection by an operator from a first mode and a second mode, wherein said first mode is an operation mode in which only said at least one first processing element among said plurality of processing elements is activated at the execution of said predetermined substrate processing, said second mode is an operation mode in which all processing elements are activated at the execution of said predetermined substrate processing, and said step (c-1) comprises the step of activating one or more processing elements in accordance with the operation mode selected. |
| Claim: | 14. The method according to claim 13 further comprising the step of: (d) halting said one or more objective processing elements having been used for said predetermined substrate processing after a predetermined time has elapsed since operation of said one or more objective processing elements for said predetermined substrate processing had completed. |
| Claim: | 15. The method according to claim 14 wherein said one or more objective processing elements are processing element(s) other than said at least one first processing element. |
| Claim: | 16. The method according to claim 15 wherein said step (a) further comprises the step of: (a-3) storing information specifying at least one second processing element which is previously selected to be optionally activated, and said step (b) further comprises the step of: (b-2) additionally activating said at least one second processing element for said predetermined substrate processing when only said at least one first processing element is initially used for said predetermined substrate processing. |
