Closed processing chamber with fume extraction system reduces chemical exposure for the user.
For instance, the distribution sequence may involve maximizing the use of the“fastest” processing chamber.
Step 216 inquires as to whether the plasma is on in the processing chamber 36, and therefore may be identical to step 224 discussed above.
As such, the gas supply section 200 can supply many different desired gas mixtures to the plasma processing chamber 12.
This unique innovation enables an unprecedented number of etch processing chamber locations and doubles the capacity of traditional silicon etch systems.
The wafer handling assembly 44 will retrieve one of the wafers 18 from the cassette 6 and transport the same into the processing chamber 36.
These differences can be readily identified to in turn identify when the processing chamber 36 should be cleaned in at least some manner.
New spectral patterns from this new plasma process will then be available to assess further runnings of plasma processes on this same processing chamber 36.
The vacuum processing chamber 15 is provided with an exhaust port and is provided with an automatic pressure control valve 22(also referred to as APC).
The highly efficient chambers are 3m long and devided in to 2 sections, each one with individual control of the airflow, to ensure even temperature in the processing chamber.
Optionally, processing chamber may be purged with nitrogen up to a pressure of about 10 Torr to about 20 Torr and then pumped down to the pressure in the range of about 30 mTorr.
That is, each main data entry 350 is reserved for storing information which is used to evaluate plasma processes which are to be conducted in this same processing chamber 36.
Another way in which this may be done is to determine when any of the spectra from the interior of the processing chamber 36 have at least a certain number of discrete peaks of a least a certain intensity.
Optionally, the processing chamber may be purged with nitrogen up to a pressure of about 10 Torr to about 20 Torr and then pumped down to the pressure in the range of about 30 mTorr, as previously described.
Entries in the normal spectra subdirectory 288 are thereby used as a“model” or“standard” for the evaluation of plasma processes conducted in this very same processing chamber 36 at some future time.
Consider that a single semiconductor fabrication facility may have up to 200-300 processing chambers and that each processing chamber in commercial production may process at least about 15-20 wafers per hour.
One aspect of any plasma process which may be monitored through the subject eighteenth aspect is to identify an occurrence of at least one endpoint which is associated with a plasma process being run in a processing chamber.
For instance, spectral data from two separate runnings of plasma recipe A on the same type of product in the associated processing chamber 36 may actually be included in the normal spectra subdirectory 288.
As noted above, these errors in the main data entries346 have preferably been identified(e.g., the cause(s) of the error has been determined), and are thereby a“known” condition which may be encountered when running a plasma process in the processing chamber 36.
The current plasma process module 250 may use this information on“dirty chamber conditions” to identify when a processing chamber 36 is in condition for cleaning, and further such that appropriate actions may thereafter be undertaken.
With appropriate gases being contained within the processing chamber 74 and under other appropriate conditions(e.g., pressure, temperature, flow rate), an appropriate voltage may be applied to one or more of the wafer pedestal 106 and the showerhead 94 to create the plasma within the chamber 74 above the wafer platform 104.
The particular gases supplied by the respective gas sources 202-216 can be selected based on the desired process that is to be performed in the plasma processing chamber 12, e.g., particular dry etching and/or material deposition processes.
Data regarding process control parameters or conditions associated with the processing chamber 36 may also be included in each of the above-described subdirectories of the plasma spectra directory 284 for a specific data entry, particularly in the case of the abnormal spectra subdirectory 292 and the unknown conditions subdirectory 296.
Each storage tank 154 b-d is fluidly interconnected with a mixer 166 by gas lines 158 b-d where the feed gases may be appropriately mixed prior to being provided to the processing chamber 74 through the showerhead 94 via the gas line 158 e.
In other words, a first group of valves 440 is opened and a second group of valves 440 is closed to supply the first gas to the plasma processing chamber 12, and then the same first group of valves is closed and the same second group of valves 440 is opened to change the gas flow to supply the second gas to the plasma processing chamber.
If the spectral data from a plasma process recorded in the unknown spectra subdirectory 296 is identified as being a new plasma process, and if a determination is made to use this spectral data as a standard for evaluating further runnings of this same plasma process on this same processing chamber 36, this spectral data may be transferred to the normal spectra subdirectory 292.
Generally, the current plasma process module 250 receives data from the current plasma process being conducted within the plasma processing chamber 36, and in all but one case(the research module 1300) compares this data or at least a portion thereof with data from one or more plasma processes previously conducted within this very same plasma processing chamber 36 to evaluate or monitor the current plasma process.
If the“response” to the inquiry of step 208 is a“yes”, the startup subroutine 204 proceeds to step 224 where a determination is made as to the status of the plasma in the processing chamber 36-specifically whether the plasma is“on” through optical analysis by the current plasma process module 250.
For example, the power may range from about 600 W to about 6000 W for a chamber processing four 300 mm wafers.
