The wafer boat 217 has a plurality of holding members for holding the wafers 200 horizontally in a state where the wafers 200 are aligned in the vertical direction.
Next, the operation of the substrate processing apparatus 10 will be described. As one of the steps of manufacturing a semiconductor device (apparatus), an example of substrate processing using the substrate processing apparatus 10 will be described. In the present embodiment, when the execution processing start time of the reserved processing task is reached, the controller 121 controls the operations of the respective units constituting the substrate processing apparatus 10 to start the substrate processing. Here, the processing task constitutes three steps of preprocessing, main processing, and post processing. First, the conveyance process of the wafer 200 is performed by the controller 121 as a pretreatment. In the present embodiment, the wafer 200 is transferred to the boat 217 as a pretreatment. Hereinafter, pretreatment will be mainly described.
When the cassette 110 is supplied to the load port 22, the cassette 110 on the load port 22 is carried into the frame 111 from the cassette carry-in/carry-out port by the cassette carry-in device. The loaded cassette 110 is automatically transferred to the designated placement unit 140 of the cassette rack 105 by the cassette transfer device 130, and is transferred from the cassette rack 105 to one of the cassette openers 21 for transfer to the placement table 122 or directly to the cassette opener 21 for transfer to the placement table 122 after temporary storage.

When the cassette 110 is opened by the cassette opener 21, the wafer 200 is picked up from the cassette 110 through the wafer inlet and outlet by the tweezers 125c of the wafer transfer device 125a, and carried into the transfer chamber 6 located behind the transfer chamber 8 via the gate valve 90 to be loaded into the boat 217. In this case, the wafer may be mounted after being adjusted by a notch alignment apparatus, not shown. The wafer transfer device 125a, which transfers the wafer 200 to the boat 217, returns to the transfer cassette 110, and loads the next wafer 200 into the boat 217.
In the loading operation of loading wafers into the wafer boat 217 by the wafer transfer mechanism 125 of one (upper or lower) cassette opener 21, the cassette transport device 130 transports the other cassette 110 from the cassette rack 105 to the other (lower or upper) cassette opener 21, and the cassette opener 21 simultaneously opens the cassettes 110.
When the wafer 200 of the number specified in advance is loaded into the boat 217, the pretreatment is completed, and the main treatment (here, the treatment recipe) is executed. The process recipe executed by the main process of the process task is a recipe for processing a substrate, and is controlled by the controller 121. When the process recipe is started, the lower end portion of the process furnace 202 closed by the furnace port shutter 147 is opened by the furnace port shutter 147. Then, the sealing cap 219 of the wafer boat 217 holding the wafer group is lifted by the boat elevator 115, and is carried (loaded) into the processing furnace 202.
After loading, the wafer 200 is subjected to an arbitrary process by the process furnace 202.

The CPU121a is configured to execute these programs in response to input of an operation instruction or the like from the input/output device 122. In the present embodiment, the CPU121a functions as a display control unit. The storage device 121c stores various screen files including the screen file for displaying the graph in the present embodiment, such as a schedule screen and a production information screen.
In addition, when a term called a program is used in this specification, there are cases where only a single processing recipe (maintenance recipe) is included, only a single control program is included, or both of them are included.
The I/O port 121d is connected to the MFCs 320 a-320 f, the valves 330 a-330 f, the pressure sensor 245, the APC valve 244, the vacuum pump 246, the heater 207, the temperature sensor, the boat rotation mechanism 267, the boat elevator 115, and the like.

Next, a substrate processing step corresponding to a main process of a processing task will be described with reference to fig. 3. In the present embodiment, the controller 121 performs a substrate processing process by executing a processing recipe. The processing recipe is a recipe for processing a substrate, which is executed in the main process, and is controlled by the controller 121. The controller 121 controls operations of the respective units constituting the substrate processing apparatus 10 to perform predetermined processing on the wafer 200.
(substrate processing step) the boat 217 on which the wafers 200 of a predetermined number are placed is inserted into the reaction tube 203, and the reaction tube 203 is hermetically sealed by the seal cap 219. The wafer 200 is heated in the reaction tube 203 which is hermetically sealed, and a process gas is supplied into the reaction tube 203 to perform a predetermined process on the wafer 200.
As a predetermined process, for example, NH3 gas as a first process gas, HCDS gas as a second process gas, and N2 gas as a third process gas are alternately supplied, thereby forming a SiN film on the wafer 200.
First, HCDS gas is supplied from the gas supply pipe 310b of the second process gas supply system into the process chamber 201 through the gas supply hole 234b of the nozzle 340b and the gas supply slit 235. Specifically, by opening the valves 330b and 330f, the HCDS gas starts to be supplied into the process chamber 201 from the gas supply pipe 310b together with the carrier gas. At this time, the opening of the APC valve 244 is adjusted to maintain the pressure in the processing chamber 201 at a predetermined pressure. When the predetermined time has elapsed, the valve 330b is closed, and the supply of HCDS gas is stopped.
The HCDS gas supplied into the process chamber 201 is supplied to the wafer 200, flows in parallel to the wafer 200, flows from the upper part to the lower part through the gap S via the first gas exhaust port 236, and is exhausted from the exhaust pipe 231 via the second gas exhaust port 237 and the exhaust port 230.
In addition, when the inert gas such as N2 is flowed by opening the valve 330e of the inert gas supply pipe connected to the gas supply pipe 310a and the valves 330c and 330d of the gas supply pipes 310c and 310d while the HCDS gas is supplied into the process chamber 201, the HCDS gas can be prevented from flowing back into the gas supply pipes 310a, 310c and 310 d.
After the valve 330b is closed, the supply of the HCDS gas into the process chamber 201 is stopped, and the process chamber 201 is exhausted to remove the HCDS gas, the reaction products, and the like remaining in the process chamber 201. At this time, when the inert gas such as N2 is supplied from the gas supply pipes 310a, 310b, 310c, and 310d into the process chamber 201 and the gap S, respectively, and cleaning is performed, the effect of exhausting the residual gas from the process chamber 201 and the gap S can be further improved.
Next, NH3 gas is supplied from the gas supply pipe 310a of the first process gas supply system into the process chamber 201 through the gas supply hole 234a of the nozzle 340a and the gas supply slit 235. Specifically, by opening the valves 330a and 330e, NH3 gas starts to be supplied into the process chamber 201 from the gas supply pipe 310a together with the carrier gas. At this time, the opening of the APC valve 244 is adjusted to maintain the pressure in the processing chamber 201 at a predetermined pressure. When the predetermined time elapses, the valve 330a is closed, and the supply of NH3 gas is stopped.
The NH3 gas supplied into the process chamber 201 is supplied to the wafer 200, flows in parallel to the wafer 200, flows from the upper part to the lower part through the first gas exhaust port 236, and is exhausted from the exhaust pipe 231 through the second gas exhaust port 237 and the exhaust port 230.
In addition, when the inert gas such as N2 is flowed by opening the valve 330f and the valves 330c and 330d of the inert gas supply pipe connected to the gas supply pipe 310b while NH3 gas is supplied into the process chamber 201, NH3 gas can be prevented from flowing back into the gas supply pipes 310b, 310c and 310 d.
After the valve 330a is closed, the supply of NH3 gas into the process chamber 201 is stopped, and the process chamber 201 is exhausted, so that NH3 gas, reaction products, and the like remaining in the process chamber 201 are removed. At this time, when the inert gas such as N2 is supplied from the gas supply pipes 310a, 310b, 310c, and 310d into the process chamber 201 and the gap S, respectively, and cleaning is performed, the effect of exhausting the residual gas from the process chamber 201 and the gap S can be further improved.
When the processing of the wafer 200 is completed, the wafer boat 217 is carried out of the reaction tube 203 by a procedure reverse to the above-described operation.
In the above-described embodiments, the case where the first process gas and the second process gas are alternately supplied has been described, and the present invention can be applied to a case where the first process gas and the second process gas are simultaneously supplied.
(example 1) fig. 5 is a process flow showing a graph display program for displaying a schedule of tasks according to the present embodiment.
When the controller 121 is started, the graph display program is started, and the controller 121 first obtains the current time. Then, the storage unit 121c performs a search to confirm whether or not a predetermined task to be executed by the apparatus exists. If no task exists, the standby state is ended or maintained. In any case, when an update button described later is pressed, the program is restarted, and the current time is acquired.
When a task is retrieved, the controller 121 obtains information of the task. Not only task information (name, recipe name, start scheduled time, end scheduled time, etc.) but also at least recipe information (name, category, processing chamber, processing data, etc.) on which the task is executed is acquired.
Next, it is determined whether a task is reserved or is currently being executed. Specifically, the acquired current time is compared with a scheduled start time of the task, and a determination is made based on whether or not the current time has elapsed the scheduled start time and based on whether or not there is device data indicating the start of the task (time data indicating the start time of execution of the task).
When a task is reserved, a preprocessing scheduled time is calculated based on task information according to preprocessing starting time and preprocessing ending time of preprocessing, main processing scheduled time is calculated according to main processing starting time and main processing ending time of main processing, post-processing scheduled time is calculated according to post-processing starting time and post-processing ending time of post-processing, and the calculated preprocessing scheduled time, main processing scheduled time and post-processing scheduled time are added to calculate execution scheduled time of the task. In order to enable the respective recognition, for example, the color display pretreatment predetermined time, the main treatment predetermined time, and the post-treatment predetermined time may be distinguished. Further, for example, when all tasks are reserved, a predetermined time for preprocessing of a task to be executed at the beginning is calculated so as to be from the current time to the preprocessing end time.
While the task is currently being executed, the controller 121 confirms which of the preprocessing, the main processing, and the post-processing is being executed. Specifically, the controller 121 determines, for example, which of the start scheduled time and the end scheduled time of the preprocessing, the start scheduled time and the end scheduled time of the main processing, and the start scheduled time and the end scheduled time of the post-processing corresponds to the current time, based on the acquired device data, based on whether or not there is time data indicating the start of the preprocessing, the start of the main processing, and the start of the post-processing. For example, if there is time data at which the preprocessing starts, it is determined that preprocessing is in progress.
When it is determined that the preprocessing is in progress, the controller 121 then compares the current time with a predetermined time for ending the preprocessing, calculates a preprocessing execution time from the start time of the task to the current time when the current time passes the predetermined time for ending the preprocessing, and calculates a preprocessing execution time from the start time of the task to the predetermined time for ending the preprocessing when the current time is before the predetermined time for ending the preprocessing.
Then, the controller 121 adds the preprocessing execution time to the main processing predetermined time and the post-processing predetermined time to calculate an execution predetermined time for the task. In addition, in the case where the task currently being executed is in the main processing and in the case where the task is in the post-processing, the calculation is performed similarly. Therefore, when the current time is in the main process, the main process execution time calculated by comparing the current time with the end scheduled time is added to the pre-process execution time and the post-process scheduled time, and the main process execution time is calculated as the task execution scheduled time.
Next, it is determined whether the task is generating a recovery condition wait. For example, when confirming whether or not the recovery condition waiting is generated in the preprocessing, the controller 121 determines that the recovery condition waiting is generated when the state of the alarm requiring the recovery operation is generated based on the acquired device data, and acquires the information of the recovery determination waiting.
When the calculation (graph calculation processing) of the execution scheduled time of one task ends, the controller 121 similarly performs the graph calculation processing for the next task, and acquires the task execution scheduled time as graph processing result information for all the retrieved task calculation tasks. Here, as the graph processing result information, the execution time or the execution scheduled time of the preprocessing, the main processing, and the post-processing of each task is also acquired.
Then, the controller 121 generates a schedule screen file (for example, shown in fig. 6) based on the acquired various device data such as the current time, task information, recipe information, graph processing result information, recovery condition waiting information, and the like, and displays the respective graphs of the tasks. The controller 121 is configured to display a line symbol corresponding to the current time on the schedule screen.
As described above, according to the graph display program of the present embodiment, when the processing start time and the processing end time are held in the task information, first, the scheduled execution time of the first task is calculated from the processing start time and the processing end time of the first task or the task currently being executed. The scheduled execution time of the reserved task is calculated by reflecting the scheduled end time of the head task to the task scheduled to be executed next and repeating the operation according to the number of the searched tasks.
Further, when the recovery condition waiting information is acquired for the task currently being executed, the controller 121 displays an icon indicating that the recovery condition waiting is generated in a predetermined space of the schedule screen as shown in fig. 8. Further, for example, when a cause button described later displayed in a predetermined area of the schedule screen is pressed, the controller 121 displays details of the cause for which the recovery condition waiting is performed on the display section.
Fig. 6 shows an embodiment of a schedule screen displayed in the operation screen of the input-output device 122 by executing a graph display program by the controller 121. The schedule screen 500 shown in fig. 6 includes a two-dimensional space in which the vertical axis is a project number cell 501 indicating the reservation order of various tasks executed by the device including the task currently being executed by the device, and the horizontal axis is task information including a task name cell 502, a PM cell 503, a recipe name, and an end scheduled time cell 504, and a date and time 505 indicating a scheduled monitoring period. Here, PM is abbreviated as PM of the processing module (Processing Module).
Further, in the two-dimensional space of the schedule screen 500, a line 506 indicating the current time, a task 507 currently being executed, which is displayed by an icon indicating the execution time of the task or the execution scheduled time, a reserved task 508, which is displayed by an icon indicating the start scheduled time to the end scheduled time, are displayed, and the task 507 currently being executed and the reserved task 508 are graphically displayed. In addition, the recipe name (process recipe 1) is displayed in the recipe name or end predetermined time cell 504.
The preprocessing step 508a, the main processing step 508b, and the post-processing step 508c of the reserved task 508 are displayed in the two-dimensional space of the schedule screen 500, and are displayed in colors predetermined in the respective steps. Although not explicitly shown, the preprocessing step, the main processing step, and the post-processing step are displayed independently, and are displayed in predetermined colors, similarly to the task 507 currently being executed.
Fig. 7 shows when the recipe name or the end predetermined time cell 504 is pressed to switch to the end predetermined time in the schedule screen shown in fig. 6.
Fig. 8 is a display example of an icon 510 on the schedule screen indicating that a recovery condition wait has been generated. It is known that the recipe 507 currently being executed is displayed with the current time 506 as a boundary. Some faults are generated in the preprocessing (or main processing), and the state of the recovery processing of the next main processing (or post processing) waiting for the faults continues. When the restoration process is performed, the icon 510 is not displayed. When the cause button shown in fig. 9 is pressed at the time of displaying the icon 510, a detailed cause of displaying the icon 510 is displayed.
Fig. 9 is a cause detailed screen 600 displayed on the display unit 122 when the cause button 511 on the schedule screen is pressed. The cause detailed screen 600 is a screen when the condition a in the restoration condition waiting cause is pressed (selected). Condition a includes four conditions of "EFEM", "maintenance", "PM1", "PM 2". "EFEM", "PM1", "PM2" are maintenance state release waiting of the EFEM as the storage chamber 9, the process module 1 as the process furnace 202, and the process module 2 as the process furnace 202, and "maintenance" is in the schedule of temporary stop due to maintenance. Further, when the restoration condition waiting is generated, the cause button 511 may be displayed in a different color on the schedule screen.
The cause of the "EFEM" (maintenance state release wait) and the method of coping with the cause are described below the cause detail screen 600. When the search cell is pressed, a screen for selecting four conditions of "EFEM", "maintenance", "PM1", "PM2" is displayed, and thus, it is possible to change the screen by selecting other conditions than "EFEM". Although not explicitly shown in fig. 8, cells that generate conditions for waiting for the recovery condition are displayed in different colors. When the OK button at the lower part is pressed, the display of the cause detail screen 600 is released, and the screen returns to the schedule screen 500.
Further, when the update button 509 displayed in the schedule screen 500 is pressed, the update of the chart display is performed. That is, the graph display program shown in fig. 5 is restarted, and the current time is newly acquired. Then, the processing flow shown in fig. 5 is executed from the present time to update the schedule screen shown in fig. 6.
Specifically, when the controller 121 detects that the update button 509 is pressed, it executes the processing flow shown in fig. 5, updates the new current time, task information, and recipe information, and accordingly, calculates the scheduled ending time of the currently executing task and the scheduled starting time and scheduled ending time of the reserved task again, and calculates the execution time and execution scheduled time of the currently executing task and the scheduled execution time of the reserved task based on the calculated scheduled starting time and scheduled ending time, and updates and displays the schedule screen shown in fig. 6.
As shown in fig. 12, an icon is displayed in the item number cell 501 so that the difference between the production task (processing task) and the maintenance task (cleaning task in fig. 12) is clearly displayed. Further, for example, an icon for identifying whether the recipe for which the task is performed is a process recipe (a recipe for processing a substrate) or a maintenance recipe (a recipe for cleaning a maintenance structural member such as a recipe) is displayed in the item number cell 501.
(embodiment 2) fig. 10 is a process flow of the graph display program of the present embodiment showing the executed task, and fig. 11 shows an embodiment of a production information screen displayed on the operation screen of the input-output device 122 by executing the graph display program.
When a button for switching to the production information screen is pressed, a graph display program of the executed task is started. First, the controller 121 obtains the current time. Then, the storage unit 121c searches for a task (executed task) that the device has executed. Ending if there are no executed tasks. When an update button, not shown, is pressed, the program is restarted, and the current time is acquired.
When an executed task is retrieved, the controller 121 obtains information of the executed task. Not only task information (name, recipe name, start scheduled time, end scheduled time, etc.) but also at least recipe information (name, category, process chamber, process data, production information, etc.) on which the task is executed is acquired. Further, device data including production information collected and stored in the storage unit 121c when the task is executed is acquired.
The controller 121 calculates a preprocessing execution time from the preprocessing start time and the preprocessing end time of the task information, calculates a main processing execution time from the main processing start time and the main processing end time, calculates a post-processing execution time from the post-processing start time and the post-processing end time, and adds the calculated execution times to calculate an execution time of the executed task. Then, the execution time is calculated for all the executed tasks. The execution time, the preprocessing execution time, the main processing execution time, and the post-processing execution time of all the executed tasks are acquired as graph processing result information.
Next, the controller 121 generates a production information screen file (shown in fig. 11) from various device data including the acquired current time, task information, recipe information, execution time of the executed task, and other graphic processing result information, and graphically displays the executed task, respectively.
The production information screen 700 shown in fig. 11 includes a two-dimensional space in which the vertical axis is a project number cell 701 indicating the order of various tasks executed by the apparatus, and the horizontal axis is task information including a task name cell 702, a PM cell 703, and a recipe name cell 704, and a date and time 705 indicating a predetermined monitoring period. Here, as in fig. 5, PM is abbreviated as PM of the processing module (Processing Module).
Further, the executed task 706 displayed by the icon indicating the execution time of the task is graphically displayed in the two-dimensional space of the production information screen 700, and the executed task 706 has a preprocessing step 706a, a main processing step 706b, and a post-processing step 706c, and is displayed by the colors predetermined in the respective steps.
When the acquired device data includes abnormal data indicating that an abnormality has occurred, the controller 121 displays an abnormality icon 707 in the item number cell 701 of the executed task in which the abnormal data has occurred. In addition, when a failure occurs in a task in execution on the schedule screen shown in fig. 6, an abnormality icon may be set in the item number cell 501 as well.
As shown in fig. 12, an icon may be displayed in the item number cell 701 so that a difference between a production task (processing task) and a maintenance task (cleaning task in fig. 12) is clearly displayed.
