Description:
FIELD OF THE INVENTION  
         [0001]    The present invention relates to a system for assisting business trades of used goods with using a network.  
         DESCRIPTION OF THE RELATED ART  
         [0002]    Conventional process of transferring or selling used semiconductor manufacturing apparatus (semiconductor manufacturing equipment) has required the following steps.  
           [0003]    A project manager prepares documents (release plan) based on the property management report, and send them to semiconductor manufacturing facilities (production lines). In each of the facilities, a person in charge reviews the equipment in the facility, and reports to the project manager whether the facility has appropriate apparatuses being applicable to the intrafirm transfer.  
           [0004]    Another document which listing up the apparatuses being inapplicable to the intrafirm transfer may be prepared as a release item list. The list may be transferred to a broker who handling used semiconductor manufacturing apparatuses. The brokers may prepare their own documents as a for-sale item list for their business.  
           [0005]    Accordingly, such the troublesome document preparation tasks are required at every stages through the project for intrafirm transfer of the used semiconductor manufacturing apparatuses. And, it is difficult for the brokers to find appropriate used goods which satisfy the buyers demands because their human resources are not limitless.  
           [0006]    As the growth of IT (Information Technology), various goods have been traded via the Internet. As well as those general goods, the used semiconductor manufacturing apparatuses may be applicable to such the trading. However, specialty of the semiconductor manufacturing apparatuses requires a system to have extra functions rather than ordinary internet auction services, because information obtained via the internet may be insufficient for making decision on purchasing the semiconductor manufacturing apparatus.  
           [0007]    Such the problem occurs in several fields handling secondhand goods, special purpose goods, highly-priced goods, and the like, because it is difficult to understand actuality or substance of those items based only on information obtained via the internet (even if it provides rich contents).

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0055]    A system for assisting business trades of used semiconductor manufacturing apparatuses (semiconductor manufacturing equipment) according to an embodiment of the present invention, will now be described with reference to the accompanying drawings.  
         [0056]    As shown in FIG. 1, the system according to this embodiment comprises a site  11  which contains information regarding to for-sale semiconductor manufacturing apparatuses.  
         [0057]    The site  11  authorizes predetermined business bodies which had completed “sign-up ” for accessing the site  11 . Therefore, the site  11  is accessible only by terminals belonging to the authorized business bodies, via a network such as the internet. The site  11  accepts entry (upload) of information regarding to the for-sale semiconductor manufacturing apparatus (for-sale data), and allows applicants for buying to view the entered for-sale data. That is, the site  11  intermediates a business trade between the parties concerned. The site  11  provides functions of searching, browsing, and entering the for-sale data, however, a function for completing the business trades (that is, “accounting” function) is omitted, because the information viewable via the internet is too insufficient to understand actuality or substances of the items (even if it provides rich contents), and inspection of actual condition is a necessary matter before purchasing.  
         [0058]    Business bodies which are allowed to access the site  11  (that is, sign-up had been completed), are categorized into “Group A”, “Group B”, and “Group C”, in accordance with their businesses.  
         [0059]    “Group A” includes main users of the cyber market provided by the site  11 . Those users may be business bodies such as enterprises, laboratories, and universities, those are potential suppliers of used semiconductor manufacturing apparatuses. Each of the business bodies in Group A obtains special software for interaction with the site  11 . The software allows the business body to upload information representing used semiconductor manufacturing apparatus to the site  11  as “for-sale item”. The software has another function to manage intrafirm transfer of equipment (including transfer between associated companies). The site  11  prepares private web site areas assigned to each of the group A members respectively for managing the intrafirm transfer. Each of the business bodies may upload a home page (HP) regarding to the intrafirm transfer to the private web site. Accesses to those private HP are controlled to maintain the private use.  
         [0060]    In response to the “for-sale item” entry, the site  11  automatically prepares e-mail including information of the latest business trade, and distributes it to the group A members. The site  11  also allows the group A members to view the latest business trade information during a predetermined period, with the access control for eliminating accesses by the other business bodies in Group B and Group C.  
         [0061]    Since the Group A is the category for the main users of the cyber market of the site  11 , a newcomer may be required to pay a membership fee. The membership fee may be appropriated for the costs of, for example, software installation, configurations for each business body, preparation of the private HP, and the like.  
         [0062]    On the other hand, Group A consists of users those intend to buy apparatuses mainly. The site  11  controls the accesses so that the group A members and the group B members are allowed to view the apparatus data after the period wherein the group A members are allowed to view the information prior to the others. The access control still eliminates group C members from viewing the information.  
         [0063]    The group B members are also allowed to sell the apparatuses. In this case, they may have several ways for entry such as using a for-sale item entry form viewable on the home page provided by the site  11 , and sending a document including necessary data for entry to the administrator of the site  11 .  
         [0064]    Any business bodies are allowed to access the site  11  after “sign up” through the home page of the site  11 . Those users are categorized into Group C. Those group C members are also allowed to sell used apparatuses. In this case, the procedures the same as those for the group B members are required.  
         [0065]    If an appropriate apparatus is found, the user notifies the site  11  that the user wishes to buy it. The service provider begins action for achievement. If an appropriate apparatus is not found, the user may enter wanted apparatus for the site  11 .  
         [0066]    A unique ID is issued to each the business body, and the business body may sets its own password. The business body thus signed-up may access the site  11 , and fills in predetermined columns on the home page with ID and password. And, they are allowed to view the home page on the site  11 . As for the group A members and the group B members, ID and password may be obtained beforehand through the sales activity of the site  11 .  
         [0067]    The site  11  specifies the group to which the business body concerned belongs, based on ID and password, and distinguishes information viewable by the user concerned based on the group.  
         [0068]    The site  11  has a search page including combo box which lists articles to be selected by the signed-up user for easy search. Articles may be, for example, category, model, maker, and the like. Fine search is available with using search query (including single word or multiple words).  
         [0069]    The apparatus list being viewable on the HP has an indicator “Offered” which indicates the status of business trades. The list also has indicators “Very New” and “New” each representing “entered in last 2 weeks” and “entered in last 4 weeks” respectively.  
         [0070]    According to the above structure, business trades of used goods are arranged through the home page on the internet, thus, the efficiency of the business trades may be improved. And the users are categorized into groups those are prioritized for the access control. Such the priority may be incentive to participate in the cyber market for potential suppliers, thus, the market will be well supplied and active.  
       EXAMPLES  
       [0071]    An example of the above embodiment will now be described with reference to FIGS.  2  to  18 .

         [0087]    Operations of the system having the above structure will now be described.  
         [0088]    (User Sign Up)  
         [0089]    To participate in business trades in the cyber market on the site  11 , user sign-up is required. A canvasser of the site  11  visits business bodies which may be categorized into group A or group B, such as semiconductor maker, to invite them to the site  11  with explaining the aim or details of the site  11 . The site  11  issues an ID to a business body which decided to participate in the site  11 . Those business bodies determine their own password. The system administrator of the site  11  registers ID, password, company name, and the like (user information) to the user information DB  112 .  
         [0090]    In case of general business bodies other than the above, they may access the server  111  via a certain internet service provider (ISP: not shown) with using arbitrary WWW browser installed in a terminal (hereinafter, referred to as user terminal  41 ).  
         [0091]    In response to the access, the server  111  transmits a top page shown in FIG. 9 to the user terminal  41 . Since the business body concerned is unregistered user, the operator may clicks “Sign In” button on the top page shown in FIG. 9 in accordance with the displayed guidance. This operation causes the server  111  to issue user ID (for example, serial number or random number), and transmits a sign-up page as shown in FIG. 10 to the user terminal  41 . The user terminal  41  displays the page.  
         [0092]    The user inputs necessary information such as company name and name of person in charge through the displayed page, then clicks “Submit” button. This operation causes the user terminal  41  to transmit ID and input information (user information) to the server  111 . The server  111  receives the user information, and enters it for the group C area in the user information DB  112  as shown in FIG. 4.  
         [0093]    (Operations for Property Management)  
         [0094]    As described above, the terminal  21  which is operated by the person in charge in the business body of Group A, has been equipped with the special program for using the site  11 . The operator executes the special program for managing their properties. To begin with, the person in charge enters information of their own semiconductor manufacturing apparatuses for the template shown in FIG. 8. Additionally, information of disposed or sold properties is deleted. Thus, the template presents helpful information representing the status of their properties to the person in charge who wants to check the status.  
         [0095]    (Operations for Intrafirm Transfer)  
         [0096]    In a case, for example, where replacement of the equipment in the group A business body produces surplus apparatuses, a section in charge notifies a property manager of it. The property manager may investigate the semiconductor manufacturing apparatuses to determine whether those are applicable to the intrafirm transfer. If it is appropriate for intrafirm transfer, the property manager arranges procedures for it. Using the site  11  may be one of the solutions to achieve the intrafirm transfer efficiently. In this case, the operator may executes the special program in the user terminal  21  to retrieve the property table shown in FIG. 8. The operator inputs a symbol (for example, “ ”) representing “upload” to the column “in-house” corresponding to the apparatus concerned to specify it, then clicks “Upload” button (not shown).  
         [0097]    This operation causes the upload function of the special program to access the server  111  via the ISP or the like, and automatically transmit ID, password, and the like. Thus, the server  111  is notified that the information of intrafirm transfer being uploaded. The upload function also recognizes updates of the symbol“ ” in the “In-house” of the property information table, and transmits the information of the apparatus corresponding to the update to the server  111 .  
         [0098]    The server  111  determines whether “Group A” in the user information DB  112  has had the entry of the notified pair of ID and password. If the entry is not found, the server  111  replies an error message saying it. On the contrary, if the entry is found, the server  111  specifies the business body concerned based on its ID, and adds the received information to the table prepared for the business body concerned in the intrafirm transfer DB  114 .  
         [0099]    If demand for facility acquisition which should be done by intrafirm transfer occurs, a facility manager of the business body in Group A may operates the browser or the like in a user terminal (hereinafter, referred to as user terminal  21 ) to access the site  11  via the ISP or the like.  
         [0100]    In response to the access, the site  11  presents the top page shown in FIG. 9. The facility manager inputs ID and password onto the top page, and clicks “Login” button.  
         [0101]    The server  111  determines whether “Group A” in the user information DB  112  has had the entry of the notified pair of ID and password. If the entry is not found, the server  111  replies an error message saying it.  
         [0102]    On the contrary, if the entry is found, the server  111  transmits a menu page shown in FIG. 11( a ) to the user terminal  21 . The user terminal  21  receives the menu page, and displays it through the browser or the like. The user designates “View intrafirm transfer” to notify the server  11  of it.  
         [0103]    In response to the selection of “View intrafirm transfer”, the server  11  retrieves the transfer information table as shown in FIG. 6 prepared for the business body concerned represented by the ID and password. The server  11  generates presentation information written by HTML (web page) with CGI support, and transmits it to the user terminal  21 . The user terminal  21  displays the received page (intrafirm transfer information) through the web browser. The page presents a list of their apparatuses for intrafirm transfer to the facility manager.  
         [0104]    If a wanted apparatus is found, the facility manager may contacts the section in charge or the like to proceed following procedures.  
         [0105]    If the intrafirm transfer concerned is concluded after the procedures, the property manager executes the special software to inform the server  111  that the apparatus concerned has been removed from the nomination for intrafirm transfer. In response to the notice, the server  111  deletes information regarding to the apparatus from the table in the intrafirm transfer DB  114  which has been prepared for the business body concerned.  
         [0106]    Accordingly, the business body in Group A is allowed to use the site  11  as its private site to exchange information of the intrafirm transfer of apparatuses. It is helpful for a section having an apparatus to be transferred and another section which wants to acquire the apparatus, to exchange information therebetween easily and promptly, thus the efficiency of the intrafirm transfer will be improved.  
         [0107]    (Operations for Selling Used Semiconductor Manufacturing Apparatuses)  
         [0108]    In a case, for example, where a certain business body has surplus apparatus caused by replacement of the equipment, a section in charge may notifies a property manager of it. If the property manager determines that the apparatus concerned is not subject to the intrafirm transfer based on the investigation, the property manager considers whether it should be sold to the outside. The property manager also considers such the matter in a case where an appropriate acceptor of an item for the intrafirm transfer exemplified above has not been found in a predetermined term.  
         [0109]    To use the site  11  for selling an item to the outside, execute the special program in the user terminal  21  to open the property information table shown in FIG. 8. Then, set a symbol representing “upload”, for example, “ ” to the column “NET” corresponding to the apparatus being subject to the intrafirm transfer to specify the apparatus for the intrafirm transfer, then click “Upload” button (not shown). This action causes the upload function of the special program, thus it establishes the connection to the server  11  via the ISP or the like and automatically transmits ID, password, and the like to notify the server  111  that the information of for-sale is being uploaded. Additionally, the upload function discriminates the apparatuses corresponding to newly affixed symbols “ ” in “NET” column, and transmit information regarding to the apparatus concernedes to the server  111 .  
         [0110]    The server  111  determines whether Group A in the user information DB  112  has had the entry of the notified pair of ID and password. If the entry is not found, an error message is sent as a reply. On the other hand, if the entry is found, the information received is added to the information stored in the item information DB  113  as shown in FIG. 5. In this case, “Entry Date” represents the day concerned, “Supplier” represents a business body specified by ID and password, and Person in Charge, Address, and the like represent the person in charge, contact information, and the like being stored in the user information DB  1113 .  
         [0111]    In accordance with the new entry, the server  111  retrieves the information concerned, and generates an e-mail as shown in FIG. 12 with retrieving e-mail addresses of the persons in charge in the business bodies of Group A, and transmit it to them. Each of the persons in charge of the business bodies of Group A is notified that for-sale information has been updated, with details of the update, asking price, and the like by the e-mail prior to the business bodies of Groups B and C.  
         [0112]    A facility manager of the business body in any of the groups A to C may operates the user terminal to access the site  11  via the ISP or the like, when intends to acquire a used semiconductor manufacturing apparatus. In response to the access, the site  11  presents the top page shown in FIG. 9. The user terminal displays the top page, and the facility manager inputs ID and password through the top page, and clicks “Login” button.  
         [0113]    The server  11  determines whether the user information DB  112  has had the entry of the pair of ID and password. If the entry is not found, an error massage is sent as a reply. If the entry is found, it specifies the business body concerned based on ID and password, and determines the group to which the business body concerned belongs. The server  111  carries out the following process in accordance with the determined group.  
         [0114]    &lt;In Case of Group A&gt; 
         [0115]    The server  111  transmits the menu page shown in FIG. 11( a ). The user terminal (hereinafter user terminal  12  because it belongs to Group A) receives the menu page and displays it through the browser or the like. The user designates “View Buy-Sell Information” and notifies the server  111  of it.  
         [0116]    In response to the notice of “View Buy-Sell Information”, the server  111  transmits the search page (search screen) as shown in FIG. 13 to the user terminal  21 . The user terminal  21  displays the received search page through the browser. The search page may has combo boxes each shows keywords (search queries) corresponding to model of the apparatus, maker, category, process, specification, price, and the like. The search page allows the user to select keywords by those combo boxes to set search queries. The user is also allowed to input keywords directly.  
         [0117]    After the search query setting, the user may click “Start Search” button. In response to this action, the user terminal  21  notifies the server  111  of the search queries. The server  111  searches the item information DB  113  for information which matches the search queries notified. The server  111  retrieves the matched information, and generates a page listing the retrieved information as shown in FIG. 14 with CGI support for example. It affixes the indicator such as “Very New” to articles entered within last 2 weeks, and affixes another indicator such as “New” to articles which had been entered within last 1 month except the last 2 weeks. Thus it is indicated which are newly entered articles.  
         [0118]    The server  111  transmits the generated page (for-sale list) to the user terminal  21 . According to the list displayed on the user terminal  21 , the user may discriminates whether it includes wanted item or not.  
         [0119]    &lt;In Case of Group B&gt; 
         [0120]    Since any services regarding to “intrafirm transfer” are not provided to the users of Group B, it is unnecessary to present the page for selecting “intrafirm transfer” to the users of Group B. Therefore, in a case where the server  111  determines a user belongs to Group B, it transmits another menu page shown in FIG. 11( b ). A user terminal (hereinafter, user terminal  31  because it belongs to Group B) receives the menu page and displays it through the browser or the like. The user designates “View Buy-Sell Information”, and transmits it to the server  111 . Then the server  111  transmits the search page as shown in FIG. 13 to the user terminal  31 . The user terminal  31  displays the received search page through the browser.  
         [0121]    After setting search queries, the user may click “Start Search” button. In response to this click action, the user terminal  31  notifies the server  111  of the search queries.  
         [0122]    Since the users of Group B are on a restriction “those are allowed to view only information entered before last 2 weeks”, the server  111  adds an extra search query “entered before last 2 weeks” to the notified search queries, and searches for-sale apparatuses for ones match those search queries. The server  111  generates a page listing the information of retrieved items as shown in FIG. 15 with CGI support for example. The indicator such as “New” is affixed to items entered within last 1 month, thus, it indicates which ones are newly entered items, however, “asking price” by the supplier are not displayed on the page.  
         [0123]    The server  111  transmits the generated page (for-sale list) to the user terminal  31 . Thus the user may discriminate whether wanted item is included or not based on the list being displayed on the user terminal  31 .  
         [0124]    &lt;In Case of Group C&gt; 
         [0125]    Operations in a case where a user belongs to Group C are fundamentally the same as those for the Group B users, however, the server  111  adds an extra search query “entered before last 1 month” to search queries notified by a user terminal (hereinafter, user terminal  41  because it belongs to Group C) in order to fulfil a restriction on Group C users: “those are allowed to view only information entered before last 1 month”. It searches for-sale items for apparatuses match the search queries, and retrieves them. Indications of asking prices given by the suppliers are omitted.  
         [0126]    As described above, search results differs in accordance with the group even if the same search queries are given. For example, as shown in FIGS.  14  to  16 , in a case where a search under the same search queries results 3 cases wherein: one was entered within last 2 weeks; another was entered within last 1 month except last 2 weeks; and the other was entered before last 1 month, all cases are presented to Group A as shown in FIG. 14 while the group B users are allowed to view information of the cases entered before last 2 weeks without asking price as shown in FIG. 15, and the group C users are allowed to view information of the case entered before last 1 month without asking price as shown in FIG. 16.  
         [0127]    If a user (in any one of groups A to C), who views the search result given by the server  111 , finds a wanted item (including simpler interests such as “Send me catalogue”, “May I visit to see it?” or “Just interested in”), the user may click “Offer” button at leftward the article concerned. In response to this click action, the user terminal notifies the server  111  that discussion for a business trade has been offered with information representing the business body and item concerned.  
         [0128]    The server  111  notifies the control terminal  116  of the received notice, and the control terminal  116  displays it on the screen. Optionally, designation of a person in charge may be carried out previously company by company or item by item, to determine a receiver of e-mails which saying that the discussion (or investigation) for a business trade has been offered. The e-mail may also include relative information representing item concerned and the like.  
         [0129]    After the above operation, the administrator of the site  11  intermidiates the business trade between the supplier and buyer, and proceeds it. The server  111 , for example, may affix a pointer to items whose “Offer” button was clicked during the stage for presenting the search result shown in any one of FIGS.  14  to  16 , to indicate which one has being offered.  
         [0130]    &lt;To Enter and View Wanted Item Information&gt; 
         [0131]    Each of the users is allowed to enter wanted items if the for-sale list does not include items they want. In this case, the user may, for example, click “Enter Wanted Item” button on the page shown in FIGS.  11 ( a ) and ( b ). In response to this action, the server  111  displays an entry page as shown in FIG. 17 on the user terminal. The user inputs necessary information through the entry page, and clicks “Enter” button. In response to this action, the server  111  enters the input information for the wanted item information DB  115 .  
         [0132]    The user may click “View Wanted Item Information” on the page shown in FIGS.  11 ( a ) and ( b ). In response to this action, the server  111  generates a page listing information entered for the wanted item information DB  115 , and transmits it to the user terminal.  
         [0133]    The user compares the contents of the list with their own to-be-released items. If an appropriate one is found, the user may contact the administrator of the site  11  to proceed following procedures for their business trade.  
         [0134]    &lt;Item Entry by Users of Group B or C&gt; 
         [0135]    In a case where the user of Group B or C intends to enter for-sale item, the user notifies the system administrator of the site  11  of their for-sale item. The administrator may, for example, operates the control terminal  116  to enter the information regarding to the for-sale item for the item information DB  113 . Or, the user may arrange an entry page which allows the user itself to enter the information regarding to their for-sale item.  
         [0136]    For example, a page for entering information regarding to the for-sale item may be presented to the user who selects “Item Entry” through the page shown in FIG. 18 which follows to the login based on necessary matters input through the login page, thus, the user may be allowed to input information through the presented page.  
         [0137]    The system for assisting the used goods sales described above is helpful for improving efficiency in buying-and-selling used goods with using homepages on the internet. And the users are categorized into groups those are prioritized for the access control. Such the priority is incentive to participate in the cyber market for potential suppliers, thus, the market is well supplied and active.  
         [0138]    Various embodiments and changes may be made thereunto without departing from the broad spirit and scope of the invention. For example, the number of the groups is not limited to 3. It may be 2 including A and C, or  4  or more groups may be prepared.  
         [0139]    Methods for item entry and intermidiation are not limited to those described in the above embodiment. Depending on the kind of item to be handled, the system may have accounting function. Items applicable to the business trade is not limited to the semiconductor manufacturing apparatus. It is also applicable for second hand goods market handling semiconductor related items such as semiconductor investigator, automobiles, houses, and the like.  
         [0140]    The system according to the present invention is achievable by not only a specialized system, but also an ordinary computer system. For example, if program sets for above described actions are installed in a computer, it may act as the servers and the like for executing the above described processing tasks. Those program sets to be installed in the computer may be supplied by an arbitrary recording medium (floppy disk, CD-ROM, or the like). In a case where some of the above described functions are achieved by OS, or by collaboration of OS and application programs, the recording medium may store the program sets other than the OS.  
         [0141]    Those programs may be distributed via a communications network by superimposing them onto carrier wave signals. For example, those programs may be uploaded to the bulletin board system (BBS) for distributing them via the communications network. Thus distributed programs may be executed under control of OS as well as other application programs, to achieve the above described processing tasks.
