These programs are an automatic transfer program, a program which converts wafer test results from a binary file to an ASCII file, a program which receives the ASCII files and performs wafer map editing, and an auto-ftp program which automatically scans data and sends data to remote locations. Additionally, multiple workstations can process data from probers simultaneously. The on-line monitor on a production line can see production results from multiple major workstations through the network drive and drive mapping functions.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to testing software. More specifically, the present invention discloses a universal and integrated wafer testing real-time monitoring software system and its open system architecture.  
         [0003]     2. Description of the Prior Art  
         [0004]     Wafer testing is an extremely important link in the semiconductor industry. However, the testing results need to be analyzed very quickly in order to improve yield. Common programs only provide a database to users from a graphical user interface (GUI). Users cannot find the root cause of low yield wafers from the database because most of them are binary files and show no relationship. Besides, it provides no E test data or ASCII file to users, therefore, it is difficult to trace wafer process errors. Yield improvement is related to wafer manufacturing processes and IC design specifications, but the present invention can perform numerous sorts of analyses to find out the root cause of low yield wafers because all data can be traced under different sub-directories. Data in all different sub-directories of this platform may be data coming from probers, data from testers, data from stdf files, data from E test machines or WAT results from wafer manufacturing processes.  
         [0005]     Generally speaking, testers for wafer testing can be of different brands and of different purposes. Major tester vendors include Teradyne, Agilent and Credence. On the other hand, TSK, TEL and EG are also three major brands of wafer probers, which are used in conjunction with testers. Additionally tester terminals may use personal computers (PCs) or workstations, and hence generate PC based or Unix based data files. Binary output files generated by wafer probers are also in different formats depending on brands. Due to marketing considerations, software from one prober vendor does not support reading binary file types of another vendor. So users must buy different supporting software to accommodate different probers and shortcomings and loopholes appear at the system integration level. Furthermore users easily subject themselves to pressure from vendors, such as they should only buy one type of prober. Additionally, they cannot generate good competition among prober vendors and have an active position in accessing technologies.  
         [0006]     Wafer testing factories in Taiwan are facing no smaller a challenge than that of foundries. In order to take orders from TSMC or UMC, testing factories must send back results as soon as possible in TSMC or UMC compatible formats. Currently it is even required to send files immediately after testing. At the same time testing factories need to handle data transfer for different IC design companies and this transfer is automatic. When using different probers, reading binary files generated from different probers and converting them into ASCII files is also a challenge because all conversions should be done by a single piece of automation software, not by different programs in different paths. Furthermore users should not perceive any difference despite different data formats.  
         [0007]     In the automation software there exists a mechanism that can tell the type of prober generating a file and call corresponding routines to read and convert a file. Moreover, accuracy of test data is also very important. Many testing factories use tester generated software bin files as their basis. But if a part of the dies on a wafer are retested, the second results only contain results of those dies retested, not results from the whole wafer. This requires a manual decision and a program to merge these test results into a file. The number of passing dies after merge and that in the hardware bin file read by a prober may become inconsistent. Normally TSMC or UMC also requires sending back both software bin files (generated by testers) and hardware bin files (generated and converted by probers). This data cannot contain any errors and cannot be changed manually with an editor. If a change is needed, then changed data become the basis due to the exceptions.  
         [0008]     Foundries have adequate manpower and resources for system level integration, however, owing to this very advantage, foundries have to spend a lot in manpower to support system integration.  
         [0009]     Therefore, there is need for a universal and integrated wafer testing real-time monitoring software system with an open system architecture, which enables data processing with very little manpower and no error, and conveniently and efficiently analyzes production data and tracks yield and yield improvement.  
       SUMMARY OF THE INVENTION  
       [0010]     To achieve these and other advantages and in order to overcome the disadvantages of the conventional method in accordance with the purpose of the invention as embodied and broadly described herein, the present invention provides a universal and integrated wafer testing real-time monitoring software system and its open system architecture.  
         [0011]     The present invention, under the condition of limited manpower support, provides unique automation software to support production and R&amp;D related departments in an effective and cost-saving manner. Furthermore, issues arising from production lines, due to personnel changes or caused by new workers unfamiliar with operation of software, or data which contains errors and cannot be send out, are eliminated. This invention has a mechanism that not only provides all backup and logging functionalities but most importantly uses files to complete all workflows required by different devices. These workflow files can be modified and maintained very easily. Most importantly, these file are managed by dedicated staff. To production line operators, operating this software involves no menu selection. It only requires clicking a few buttons to go to a particular wafer from a particular lot to generate all data. Therefore this pushes the foolproof mechanism to a limit and at the same time does not affect making menus during engineering development. Because of this, this invention provides software that is very easy to use. For example, it only takes a single ten-minute training session for operators to become skilful and not error prone.  
         [0012]     Other common software on the market cannot provide this function, because they have different architectures than the present invention. Databases of common software are usually stored in locations unknown to users and it is necessary to execute such software in order to see data from different lots. This invention uses a known sub-directory hierarchy; inside the software users can switch freely. Furthermore, the data processing speed of this invention is more than five times of that of typical software on the market.  
         [0013]     All results produced by this invention are placed under a fixed path. Therefore anyone can easily locate a file under that fixed path regardless of the file type. It isn&#39;t required to operate the software in order to locate data. On the contrary, any text editor can open any data file after the file has been generated in real-time by this invention. Wafer map files consist of both text and graphics files. The graphics files can be opened and edited with a wafer map editor alone. This invention is a system formed by a network of four mutually support programs. Therefore, under normal operating conditions of the first receiving and sending program, the other three programs can all perform any upgrade without affecting data transfer in production lines and without data loss since after the upgrade the automatic data transfer program can re-send data not yet transferred to the network drives according to its built-in intelligence.  
         [0014]     The present invention provides a system level mechanism targeting all sorts of possible issues, and this mechanism can solve all imaginable problems. This ultimately leads to a road to success for the semiconductor testing industry. It not only puts users on the same track as the rest of the world but also frees them from the nightmare of being controlled by others.  
         [0015]     For other software on the market, an upgrade requires a complete production line shut down and production can resume only after the upgrade has been completed. Because of this, loss of data and retesting in production create great disturbances. Many times carelessness not only makes it necessary to retest wafers but also increases number of returns from customers since dies are deemed defective owing to additional probe marks caused by retesting.  
         [0016]     An objective of the present invention is to provide a universal and integrated real-time processing system for wafer testing data, enabling data processing with very little manpower and no error. This system provides a very convenient and efficient analysis platform for research with high stability and simultaneity of production data and subsequent yield tracking and yield improvement.  
         [0017]     Another objective of the present invention is to improve the fixed architecture of common software, and to adopt an open architecture. In using the software platform of this invention, when entering, using and exiting this software, users are empowered to create interface files for communication with external software (specified in information files) to achieve communication of this software with external systems through reading data files in the current working directory provided by this software using an external communication interface specification file. Therefore all special requests can be accommodated using this framework without any need of modifying the main program. As a result, errors can be avoided and the labor cost of frequently modifying the main program can be eliminated.  
         [0018]     Another objective of the present invention is to provide a dynamic binning change by using associated external programs to extract datalogs from stdf files and change limits based on statistical process control (SPC) analysis and recreate its binning file. This is accomplished based on the flexible architecture which is completely different from other common software. The newly recreated binning file could rescue a lot of marginal dices and improve wafer yield, however, every minor change could be easily monitored under each wafer lot.  
         [0019]     Another objective of the present invention is to also add many foolproof mechanisms in addition to providing easy operation and speed in high efficiency. Setting up and locking of operating parameters in an information file makes operators less error prone and preserves flexibility for line management to modify the set-up file. It can completely meet special requirements without having to change the main program.  
         [0020]     Another objective of the present invention is to remedy the serious flaw of being able to process data of only one specific prober in common programs, and to provide a framework for data from three major probers on the market, as well as data from a user defined prober. This allows data from any future probers manufactured to be processed using a special definition. This means that all intellectual property rights are held by the software owner instead of being controlled by prober manufacturers.  
         [0021]     This invention provides a wafer testing real-time monitoring software system and its unique open software architecture achieves real-time monitoring of wafer test results and on-line changing of externally hooked software to satisfy special needs of customers without changing its main program. The software structure of the present invention can receive and process binary files from different probers and convert these into readable ASCII files. This invention basically consists of four software programs that can operate independently.  
         [0022]     The first program is an automatic transfer program, whose basic function is to receive from the production line, binary files or ASCII files in either PC format or Unix format. According to a user defined information file, the program scans for incoming files and then sends out to paths specified in the information file using a network drive function.  
         [0023]     The second program converts wafer test results from a binary file to an ASCII file, and has a universal on-line monitoring interface that shows test results in real-time on on-line monitors in production lines through its network drive and drive mapping functions.  
         [0024]     The third program receives ASCII files from the second program and performs wafer map editing. Users can call up this editor in different workstations for such wafer map editing. An imperfect or contaminated die can be marked by clicking the mouse pointer over the die. Even if the die tested okay previously, it has to be removed like a bad die. The die data are then saved into a file, which is used to generate off-line inking or an inkless file. All related files are sent out after that. This software also allows mouse click input from users. Alternatively, it also allows machine generated data files about wafer surface imperfection and contamination to be integrated with raw test data file by external software in the postprocessor and the resultant test data to be used instead of mouse clicking input. After all editing is done, the program sends all files to the workstation running the fourth program. The software uses an output trigger file and an error trigger file generated by external software in the post processor as a final gatekeeper to decide whether to send files to the fourth software or not. This is a flexible interface of this invention, and can handle requirements for different products and customers. Because external software is defined in information files according to each individual product, it is not necessary to change the main program to handle any new requirements; all it takes is writing new external software. Inside this program, there are 4 different wafer maps binning selections. All these binning files not only provide a cross check for hardware binning, software binning, stdf binning and process binning but also provide a platform for user to extract data from stdf data log files and create dynamic limits and then recreate a new binning file to rescue some marginal fail die after statistical analysis is made. By doing this, users can improve the yield if process data drifts from lot to lot but still maintain the control of the quality of test while everything is under user&#39;s control from remote terminal service. This unique flexibility can let design houses control everything and save a lot of cost.  
         [0025]     The fourth program is an auto-ftp program, which automatically scans data and sends data to remote locations. This software is easy to set-up, easy to edit, and provides automatic debugging and convenient to use functions. It also provides a “backup file” function after sending out files. If it is unable to transmit a file, it generates an error message log file so that a user can easily see reasons for any errors and find corresponding solutions. Individual batch files can be set up to target major customers. Using information files set-up by the user, the program can transfer different files related to different products to different subdirectories of different ftp sites according to customer requests. This program provides text file functions for the above-mentioned files. Therefore transition between workers in adjacent shifts is easier and less prone to error. Processing of emergency files is also quicker.  
         [0026]     These four programs can work independently. However, owing to their mutual support functions, they can form a seamless network to handle requests both from production lines and from customers. Moreover, the second and the third program can call pre-processor, post-processor and user procedures. Therefore no frequent modification to this open software architecture is required once it is completed. Any special requirement can be met by modifying external software. External software exists in batch files for pre-processor, post-processor and user procedures.  
         [0027]     In addition, this invention processes a universal integration function which can process files from different types of probers like TSK, TEL and EG. The unique design of this invention enables it to process files in these three different formats generated by the above probers in a uniform manner. After processing, the result is in a standardized ASCII format and the editing program can further process it. To meet requirements from different customers, final output files can be made into different device dependent formats by using external software to facilitate sending out of the file.  
         [0028]     Another major characteristic of this invention is that multiple workstations can process data from probers simultaneously. The on-line monitor on a production line can see production results from multiple major workstations through the network drive and drive mapping functions. After which it can take the next processing step, which is to re-generate a raw data floppy diskette depending on whether a retest or a fail die retest is necessary. This greatly reduces cycle time of wafer testing. This invention also has a multi-processing function. As a result it can minimize risks of data loss. It also has a built-in intelligence function, so upgrading of any of the four programs does not affect data communication between them.  
         [0029]     To summarize, this invention aims at improving production line monitoring efficiency during wafer testing, minimizing problems during upgrade of data processing automation software and improving efficiency in handling of abnormalities. As a result, it greatly smoothes the work flow. The open software architecture makes it possible for all R &amp; D and production departments to create different external programs to suit their needs. After a supervisor includes these into the device definition file, the programs can process data following instructions in this file. In addition, this file can also disable any menu items in the editor program and prevent operators from choosing the disabled item thereby make production lines foolproof.  
         [0030]     These and other objectives of the present invention will become obvious to those of ordinary skill in the art after reading the following detailed description of preferred embodiments.  
         [0031]     It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.

 Functionality: 
 
         [0103]     Autoprocess.exe (Win32 program)  
         [0104]     Description: periodically scans through all subdirectories under a source directory and automatically processes any existing TSK format binary wafer file based on a given lookup table. It calls tsk2tsmc.exe for each binary wafer file to produce TSMC format ASCII wafer file and other files for later use by editor.exe. The following is the list of output files that tsk2tsmc.exe produces and their naming convention: 
        mark0001.txt, i.e., “dstMarkFile” in the description of tsk2tsmc.exe     map — 0001.txt, i.e., “dstWaferMapt” in the description of tsk2tsmc.exe     dstTsmcAsciiFile, i.e., “dstTsmcAsciiFile” in the description of tsk2tsmc.exe     dstTsmcAsciiFile.log, i.e., “dstTsmcAsciiFile.log” in the description of tsk2tsmc.exe     map.inf     map._lhs.inf     test.txt     test_lhs.txt        
 
         [0113]     Please refer to the description of tsk2tsmc.exe for more detail on these output files. All processed files are moved to a backup directory. It assumes the directory structure as shown if  FIG. 22 .  
         [0114]     It is run in minimized mode since there is no need to interface with the user. 
    Usage: autoprnt [-d] [−fNetdrive.lst]-linflookup.txt-Ittellookup.txt-lootherlookup.txt [-n] [-sSrcPath] [-r7] [-t30] [-w]   
 
         [0116]     Example: autoprnt -t1 -w -d -sd:\monitor \map -fnetdrive.txt -linflookup.txt- Ittellookup.txt -lootherlookup.txt  
         [0117]     Example: x:\monitor \map\autoprnt -t0.5 -n -d -sx:\monitor \map -fx:\monitor \map\netdrive.lst  
         [0118]     -lx:\monitor \map\inflookup.txt-Itx:\monitor\map\tellookup.txt - lox:\monitor\map\otherlookup.txt  
         [0119]     Note: the drive specified in x:\monitor\map\netdrive.lst is relative to current machine (the machine that starts autoprnt), not x drive (the machine where autoprnt resides.) So, if x:\monitor\map\netdrive.lst specifies ‘c’, it refers to c drive for current machine.  
         [0000]     Arguments: All arguments&#39; order is insignificant.  
         [0120]     -d

Any line starts with ‘;’ is a comment line and is ignored by the program. If this argument is specified, all output text files will be duplicated to the corresponding directory in network drives as well as to \tsmc\EdaData\device\lotNo in all network drives. This argument is optional.  
         [0124]     Example of the network drive list file which specifies five network drives, H, X, Y and Z will look like this:

         [0452]     The following is a description of the present invention as illustrated in the figures.  
         [0453]     As shown in  FIG. 1 , the autoxfer program runs under PC DOS or Windows and the PC connects via a network to another with PC Linux installed. The PC running Linux has Samba software installed so that the DOS PC can treat the Linux PC as a network drive. The DOS PC is responsible for receiving data files from any PC based testers or probers in the testing area. The Linux PC is responsible for receiving data files from any Unix based systems.  
         [0454]     The autoxfer.exe program following instructions in an information file (ioinfo.txt) sends data files under scanned directories to other systems as shown in  FIG. 2 . Therefore prober data are frequently and simultaneously sent to multiple systems running autoprocess.exe. After systems PC1, PC2, PC3, PC4, PC5 . . . running autoxfer.exe have received files, autoprocess.exe scans incoming data files once every minute. If it finds a data file, it converts the binary file into an ASCII file, then moves the original binary file into the back-up directory and also moves the conversion output into a fixed directory as shown in  FIG. 3 .  
         [0455]     According to network drive assignment, files are sent to local drives as well as an editor PC to facilitate editing. The systems PC1, PC2, PC3, PC4, PC5 . . . which run autoprocess.exe all have identical internal sub-directory name and contents, so every pair of PCs can back up each other by assigning network drives. Two PCs running autoprocess are set up to transfer converted data to two editing PCs; PC21 and PC22. So beside the local drives of the PCs running autoprocess, data for an editing PC also exist on PC21 and PC22. Therefore the system has a complete backup and machines going down are not a problem. Every PC running autoprocess.exe can connect to up to ten on-line monitor PCs by using drive mapping of network drives. The ten-monitor limit is imposed by Windows. So PC100, PC101, PC102, PC103 . . . PC200 on the production line can be used as on-line monitors. Batch files can be set up there and the drive mapping file in C drives of the PCs controls drive mapping between monitor PCs and the autoprocess PCs. The monitors running on the on-line PCs see the same thing as the autoprocess PCs. The monitors run on the on-line PCs but the database resides on the autoprocess PCs. All data generated from the production line are available on the monitors of the on-line PCs within one minute. If data are not available, it means either data files have not been generated or transfers were not successful.  
         [0456]     If any test has no data file, it means everything needs to be retested. There will be many risks in retesting. For example, one or two additional probing marks will be made during probing. Generally speaking, customers do not allow more than three probing marks since it would cause difficulty in wire bonding of pads. If a low yield wafer is to be retested normally, retesting is targeted at failed dies only, but it requires a raw data file for the whole wafer. This issue can be solved by the on-line monitor in  FIGS. 9, 10 ,  11 ,  12  and  13 . It is only required to click on the right on  FIG. 13-2  to select the wafer that needs to be retested, and to click the “floppy” button so that all retest data will go onto a floppy. A retest can be done as soon as the floppy is inserted into a prober. Operations like this are extremely important to a production line since once any problems happen, data must be available immediately in order for the problem to be fixed.  
         [0457]     After data are sent to an editing PC, a product engineer can use the network to connect to either one of the two editing PCs that mutually back up each other. The engineer can perform file transfer based on status of the wafer map check. All engineers using this editing PC can configure their local PCs to be on-line monitors and work on their PCs without affecting each other. Some engineers only look at test results, some process wafer data file for a whole lot. All final results are shown in  FIG. 13-3 . In this figure, if the color of the check box on the left is white, it means the data are in the backup directory; if the color is green, it means data are in the working directory. In this case after moving the mouse to the check box on the left of the figure to select a wafer, a user moves the mouse to the “Run Tsk2tsmc” button and clicks, and the autoprocess.exe program will call tsk2tsmc.exe to perform data conversion again for the wafer.  
         [0458]     After conversion, the user clicks the refresh button and the data will be shown again at the bottom of the screen and the associated check box will be green indicating the data are in the working directory.  FIG. 7-1  shows batch file auto.bat used during execution of autoxfer.exe.  
         [0459]      FIG. 7-2  shows the input and output information file (ioinfo.txt) of autoxfer.exe. From this file it can seen that any file scanned from c:\monitor\map\p* can be transferred to sub-directories corresponding to d:\monitor\map\p*. And the asterisk “*” in p* is a wildcard, meaning p* can be either one of p001, p002, p003 . . . p100, which are data from different probers. In path d:\monitor\map\p*m,n,j,k the “m,n,j,k” means drives m, n, j and k. The path is the same as that of the d drive. Hence there is no need to write another four lines. In addition the information file (devlookup.txt) shown in  FIG. 7 . 3  is a corresponding look-up table. The “\device\cp#” in ioinfo.txt is the incoming “directory\005-soft\cp1” and the out-going “directory\device_#s” is “\005” (defined by devlookip.txt).  
         [0460]     By this conversion, any data from the production line can be placed into correct sub-directories through autoxfer.exe for use by the software of the invention. If a transfer is not successful, the file whose transfer failed is put into a sub-directory corresponding to the name of the failing drive for transfer in the next scan. Files in the source directory are still moved into the back-up directory after the scan.  
         [0461]      FIG. 8  shows that parameters in all command lines which are explained in detail in the software description.  FIG. 9-1  shows the message of ownership of this program once the editor program is executed.  FIG. 9-2  and  FIG. 9-3  show different pull down menus under “Action” and “Tools”. When pull down menu “Retest Devices” is selected, FIGS.  10  to  13 - 1  explain how by following sub-directory hierarchy in the database to systematically enter relevant screens. Such as to see test results and to take related actions, like selecting wafers with small squares on the left of  FIG. 13-2  and generating retesting data on floppies by clicking the button in the lower right.  
         [0462]     In addition an operator can select a wafer using check boxes on the left, then clicking the button in the lower left to execute the binary to ASCII program to select correct wafer yield data into the working directory (indicated by green in the square) shown in  FIG. 13-3 .  
         [0463]      FIG. 13-4  shows the window if “View Lot” pull down menu is selected and it shows more detailed information about device setup file name and prober number.  
         [0464]      FIG. 13-5  and  FIG. 13-6  show all records about this lot if “View Wafers Statistics” pull down menu is selected so that user knows everything about this lot including several incomplete test data files for the same wafer.  
         [0465]      FIG. 13-7  shows the window if “Find Lot/Prober” menu is selected so that a user can specify all related concerns to find out the data file.  FIG. 13-8  shows the finding of the searching from data base file.  FIG. 13-9  shows the window if “Run Editor” is selected. Then, the editor program under a different directory can be selected by the user and the editor program can be invoked.  
         [0466]      FIG. 14  shows the screen display when the editor program is in use.  FIG. 14-5  shows the third function software, which has its own routines for displaying wafers, instead of using routines in Windows. This enables effective control of screen coordinates of every die on a wafer and allows clicking selection by moving the mouse cursor over the die. When the mouse pointer is moving over the wafer map, the lower right corner of the map shows the wafer coordinate and binning number of the die below the cursor. The die under the cursor is also highlighted with a white frame.  
         [0467]      FIG. 15  is the screen display after directly entering the “Transfer Lot Data” option from the Action pull down menu in autoprocess.exe during wafer editing without using the editor program.  FIG. 15-3  shows that all wafers can be selected to be transferred.  FIG. 15-4  shows that the wafer data file is transferring to the ftp station.  FIG. 15-5  shows the summary of final transferred results.  
         [0468]      FIG. 16  is the screen display after entering the “Transfer Lot Data” option during wafer editing when the editor program is being used. The screens are very similar to that of  FIG. 15 . However, while the editor program is running, a user can edit the wafer map and then do the data file transfer.  
         [0469]      FIG. 17  shows a screen display of all options in different pull down menus of the “Edit” option when the editor program is being used.  FIG. 17-1  shows that user can select the Edit menu and then the submenu for marking unwanted die under the 5 different stations (IQC, CP1, CP2, INK, V/M, P-SL/A) so that the user in different station such as INK (offline inking station) can mark out the die by selecting the INK sub menu and then moving the mouse cursor to that die and clicking it since some problem has been found on this particular die. A character “N” is marked on that die and then it will be saved as a bad die once the whole wafer data file is saved as shown in  FIG. 17-2 . This marking will show up if a user wants to open this wafer map file again.  
         [0470]     By choosing “Inkless File Output”, a window will be displayed as in  FIG. 17-3 . Users can choose  3  major inkless wafer map file formats for 3 major assembly houses (Ankor Anam, SPIL, and ASE). Then users can select wafers to be transferred and inkless files will be generated and transferred to the ftp station as shown in  FIG. 1 .  
         [0471]     Users can also select “Display Options” and then a small window will be displayed as in  FIG. 17-4 . Due to the large number of die on 12 inch wafers and efficiency consideration of locating the die, 4 partitions or 16 partitions button selection can be selected. As shown in  FIG. 17-5 , when the 4 partitions option is selected and the mouse is moved to the 3 rd  quadrant and clicked, only 3 rd  quadrant die will be displayed and the X, Y coordinates are also auto scaled to that quadrant. Users can move the mouse to a particular die and click it to select that die in order to mark it out.  
         [0472]      FIG. 17-6  shows that the 16 partitions option is selected and one of the 16 partitions is selected later.  FIG. 17-7  shows that another one of the 16 partitions is selected and the number shown X, Y coordinated in brackets and that die is bin1 on site  4 .  FIG. 17-8  shows the “Show Wafer Number List” and “Show Site List” in the “View” menu.  
         [0473]      FIG. 17-10  shows that both of the above selections are checked and 2 small windows are displayed and can be further selected based on different site and different wafer by clicking the mouse cursor on that site number or wafer number.  
         [0474]      FIG. 17-9  gives an example of wafer number  1  and site number  5  being selected and only the die on site  5  will be displayed.  FIG. 17-11  shows the “select overlay” selection item can be selected and  FIG. 17-12  sub window will be shown and users can choose one of the 4 different wafer maps based on 4 different binning methods. These binning methods are 1. hardware bin, (from prober)  2 . software bin, (from test program)  3 . stdf bin, (from standard format data files)  4 . process bin, (from E test or wafer process data testers). Each wafer soft binning files are under the same device and lot directory but different binning subdirectory. All these binning maps can be compared side by side to tell what reason caused the low yield wafer lot and give hints on how to improve the yield by tuning the related process parameters.  
         [0475]      FIG. 17-13  displays each die locations yield report by overlaying whole lot of wafers on that particular die. For example, on location x=2, y=23, yield is 80% for all wafers on that die and this die is site  32 .  
         [0476]      FIG. 18-1  shows a screen display of all options in different pull down menus of the “Tools” option when the editor program is being used.  FIG. 18-2  shows the window once “Launch User Procedure” is selected. Moving the mouse over the user procedure program and clicking it, the program will be executed. These user procedures are defined inside the user procedure information file. According to different requirement, users can do data analysis while running the editor and accessing the database. This procedure could be a yield report bar chart in a specified time frame and specified prober and device.  
         [0477]      FIG. 18-3  shows the window when “Edit Hardbin Wafers Information” is selected. It shows all wafer ID device setup file names and prober names.  FIG. 18-4  shows the window when “View Hardware bin Lot Information” is selected. Users can move the mouse to single select or multiple select several wafers with corrected wafer yield and then transfer these wafer files to the ftp station.  
         [0478]      FIG. 18-5  and  18 - 6  show the windows when “Edit software bin wafers information” and “View Software bin lot Information” are selected separately. Either hardware or software related selections can be selected. They can not be selected at the same time unless the user has gone up one level to switch the selection in 4 of selections “Hardware bin”, “Software bin”, “Stdf bin”, “Process bin”. For “stdf bin” and “Process bin”, selections can be added to the program in order to edit wafer information and lot information.  FIG. 18-7  shows the hardware bin and software bin-comparing result once “Compare Software and Hardware bin” is selected. The result shows the same pass die count and gives the check mark “OK”. Otherwise, the check mark will be “FAIL”. If it is fail, this data file is not sent out.  
         [0479]     This invention has many foolproof mechanisms. Some information files, like the map.inf, are generated by the tsk2tsmc.exe program and transferred to the lot directory. If an operator uses a wrong set-up file in a prober which results in errors in the map.info file, the supervisor can create a correct map.inf file in the parent device directory. The editor program gives precedence to the map.inf file in the parent directory. Certain information files, like the softmap.inf file, are created for testers or other machines. All such files are stored in device directories.  
         [0480]      FIG. 19-1  shows the corresponding batch file when the winftp program is in use.  
         [0481]      FIG. 19-2  shows the input output information file (iomarvell.txt) when the winftp program is in use. The first line shows the IP address, user name and password used by the ftp. The second line shows the path of the device that is scanned by the source terminal. All data in the inkless sub-directories of sub-directories under this path need to be transferred by ftp. This switch can be defined multiple times to send out different data. If no switch is defined, all files under all sub-directories of the lot of the device are sent out using ftp.  
         [0482]      FIG. 19-3  shows the screen display during execution of the fourth program, which performs automatic external transfer. All file sent out are displayed on screen. If the program is not scanning, the screen shows the waiting state.  
         [0483]     The look-up table in  FIG. 20  explains the flexible design of this invention. This file prober_tester.txt is an information default file which autoprocess.exe must read.  
         [0484]     The look-up table in  FIG. 21-1  and  FIG. 21-2  explains the flexible foolproof design. The file defdev.info is an information file which autoprocess.exe and editor.exe must read but from different directories.  
         [0485]     It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the invention and its equivalent.
