Description

[Technical Field]

[0001] FIELD OF THE INVENTION Embodiments of the present invention relate to a component manufacturing apparatus and a semiconductor-carrying component. [Background technology]

[0002] Conventionally, in order to efficiently carry out operations in the manufacturing process of IC modules (semiconductor chips) mounted on IC cards and the like, a technology using COT (Chip On Tape) is known, in which IC modules before data is written are aligned and attached to a long tape-like base (e.g., a film). In a component manufacturing device using COT, for example, the COT is moved at a constant speed in the longitudinal direction by engaging the teeth of a conveying sprocket rotating at a predetermined speed with sprocket holes provided on both sides of the tape-like base along the longitudinal direction of the COT. Then, the component manufacturing device sequentially performs processes such as writing predetermined data and inspecting each IC module as the COT moves. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2021-005224 Summary of the Invention [Problem to be solved by the invention]

[0004] There are multiple types of data to be written to each IC module carried on a COT, for example, depending on the type of IC card that the IC module is mounted on. Currently, this data writing is performed by workers who, according to a production plan, assign instructions to match the information to be written with the target IC module (COT). For example, workers visually check the identification value (e.g., a combination of letters and numbers) printed on the label attached to the COT reel on which the COT is wound, select the data corresponding to the identification value from the interface screen of the data writing device, and execute the writing work instruction. As a result, there have been cases where incorrect data has been written to the COT due to human error. Furthermore, when the required number of IC modules for each shipping destination is cut from the COT with the written information, there have been cases where incorrect quantities have been written.

[0005] The present invention has been made in consideration of the above, and aims to provide a component manufacturing apparatus and a semiconductor-carrying component that can easily and reliably suppress human error in the manufacture of IC modules using COT. [Means for solving the problem]

[0006] The component manufacturing apparatus of the embodiment includes a conveying unit, a code information attaching unit, an information reading unit, and a control unit. The conveying unit conveys a semiconductor-carrying component, on which a plurality of IC modules are aligned and supported on a long tape-shaped base, in the longitudinal direction of the tape-shaped base. The code information attaching unit groups the IC modules by manufacturing type and attaches code information indicating additional information usable in the manufacturing process to the tape-shaped base. The information reading unit reads the code information. The control unit executes the manufacturing process, which includes at least a data writing process for writing data to the IC modules, in accordance with the additional information based on the read code information.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configurations of the embodiments described below, as well as the actions and results (effects) brought about by the configurations, are merely examples and are not limited to the following description.

[0009] For example, one known manufacturing process for IC modules (IC chips) mounted on IC cards uses a COT (sometimes called a "semiconductor-carrying component"). The COT manufacturing process is composed of multiple steps. As shown in FIG. 1, the COT manufacturing process includes, for example, manufacturing steps S1 to S5. Manufacturing step S1 is a process of aligning (carrying) multiple IC modules on a long tape-like base (e.g., a film-like tape) to form a COT. Manufacturing step S2 is a process of adding code information to predetermined positions on the COT. Manufacturing step S3 is a process of reading the code information attached to the COT and writing the predetermined information to the IC modules. Manufacturing step S4 is a process of reading the code information attached to the COT and cutting the COT into predetermined lengths (lengths containing a predetermined number of IC modules) based on, for example, the requirements of the shipping destination. Manufacturing step S5 is a process of winding the cut COT onto individual reels. In such a COT manufacturing process, each step is performed sequentially while the tape-like base T is transported in the longitudinal direction.

[0010] 1 is an exemplary schematic system configuration diagram showing the configuration of a component manufacturing apparatus 10 according to an embodiment and manufacturing processes S1 to S5. In other words, component manufacturing apparatus 10 of this embodiment is a COT manufacturing apparatus.

[0011] The part manufacturing apparatus 10 is composed of a control unit 12 (also called a control unit), a base supply unit 14, a conveying unit 16, a COT module manufacturing unit 18, a code information attachment unit 20, an information reading unit 22, an information writing unit 24, a cutting position detection unit 26, a cutting unit 28 (also called a base separation unit), a COT winding unit 30, etc.

[0012] The control unit 12 performs overall control of the part manufacturing apparatus 10. The control unit 12 can be configured with computer resources such as a general PC or server. The control unit 12 is configured with, for example, a central processing unit (CPU), read-only memory (ROM), random access memory (RAM), a storage unit such as a hard disk drive (HDD) or solid-state drive (SSD), a communication interface, an input / output interface, a display device, etc. The control unit 12 controls the code information attachment unit 20, information writing unit 24, cutting unit 28, etc., based on production instructions (such as the type of information (data) to be written to the IC module and the number of units to be produced) issued by the manager W in accordance with the production plan and detection results obtained during production.

[0013] The base supply unit 14 is controlled by the control unit 12. The base supply unit 14 applies a predetermined tension to the long tape-shaped base T wound around the disc-shaped supply reel TR, and rotates the supply reel TR, for example, clockwise in Fig. 1, to send the tape-shaped base T toward the conveying direction A to the conveying unit 16 at a predetermined conveying speed.

[0014] The conveying unit 16 supports and moves the COT 32, which is a tape-shaped base T fed from the base supply unit 14 and on which an IC module is carried, in the conveying direction A. On both sides of the conveying unit 16 in the conveying direction A, for example, a plurality of sprockets 16a for driving the conveying and guide rollers 16b are arranged at regular intervals. The sprockets 16a are controlled to rotate clockwise at a constant speed by a drive source (e.g., a motor, etc.) not shown. Note that some of the sprockets 16a may be guide sprockets that do not include a drive source.

[0015] The teeth formed on the outer periphery of the sprocket 16a engage with sprocket holes provided on both sides of the tape-shaped base T (COT 32 carrying an IC module) in the longitudinal direction (transport direction A), and move the tape-shaped base T (COT 32) in the transport direction A at a constant transport speed (including when the base is temporarily stopped for data writing or cutting processes). Details of the tape-shaped base T (COT 32) and the sprocket holes will be described later.

[0016] In the manufacturing process S1, the COT module manufacturing unit 18 sequentially aligns and arranges a plurality of IC modules cut out from a wafer on a tape-shaped base T to create a COT 32 carrying a plurality of IC modules before data is written.

[0017] FIG. 2 is an exemplary and schematic explanatory diagram showing the configuration of the COT 32 used in the part manufacturing device 10, the code information (e.g., QR code (registered trademark) 34) described later that is attached to the COT 32 in the manufacturing process S2, and the manner in which the QR code 34 is read in the manufacturing process S3.

[0018] 2, the COT 32 is configured such that a plurality of IC modules C are aligned and supported on a long tape-shaped base T. That is, the tape-shaped base T has a support area F for supporting the IC modules and a gap area P (code information attachment area) in which the IC modules C are grouped by production type and in which code information (QR code 34) indicating additional information usable in the manufacturing process can be attached. The tape-shaped base T has a configuration similar to that of, for example, a long roll film, and is provided with guide portions 32Ga, 32Gb, each composed of a plurality of rectangular sprocket holes 32a, for example, spaced apart at regular intervals on both sides of the length direction (conveyance direction A, long length direction) of the resin tape.

[0019] Between the two rows of guide portions 32Ga, 32Gb, IC modules C coated with resin or the like are aligned, for example, in two rows along the transport direction A. Note that the number of rows of IC modules C is just an example, and may be one row or three or more rows.

[0020] The teeth of a sprocket 14a provided on the conveying unit 16, which rotates, for example, clockwise, are sequentially engaged with the sprocket holes 32a of the guide unit 32Ga (32Gb), thereby conveying the COT 32 in the conveying direction A at a constant speed.

[0021] Returning to FIG. 1 , in the manufacturing process S2, the code information attachment unit 20 is controlled by the control unit 12. The code information attachment unit 20 groups the IC modules C carried on the COT 32 by manufacturing type, and attaches code information (QR code 34) indicating additional information usable in the subsequent manufacturing process to the gap region P of the tape-shaped base T. Note that although the basic structure of the IC modules C carried on the COT 32 is the same, the information (data) written to the IC module C differs depending on the type of object (e.g., IC card) into which the IC module C is to be mounted. Therefore, for example, when the IC module C is mounted in an IC card, the manufacturing type of the IC module C is the type by the issuing company of the IC card (Company A, Company B, Company C, etc.) or the type by purpose, such as a driver's license, passport, or employee ID card.

[0022] The code information attached to the COT 32 may be, but is not limited to, a one-dimensional code (e.g., a barcode) or a two-dimensional code (e.g., a QR code). In this embodiment, as described above, an example in which a QR code 34 is attached as the code information is shown.

[0023] 2, the QR code 34 is attached at a predetermined position among a plurality of gap areas P (code information carrying areas) formed in the transport direction A of the IC module C carried on the tape-shaped base T. The QR code 34 may be attached, for example, by being printed directly in the gap area P, or by printing the QR code 34 on a mount and pasting it in the gap area P. Note that the manner in which the QR code 34 is attached is not limited to this. In this embodiment, an example is shown in which the code information attachment unit 20 is configured as a two-dimensional code printer and the QR code is printed directly on the tape-shaped base T.

[0024] In this embodiment, the QR code 34 has multiple functions as described above. One function is a marking function for grouping IC modules C by production type. As described above, in the manufacturing process S2, the COT 32 is supplied with IC modules C of the same structure carried on a long tape-shaped base T wound around a supply reel TR, for example, in the hundreds of thousands. The information writing unit 24 then writes different information for each production type of IC module C, for example, in the tens of thousands or thousands. For this reason, it is necessary to group the IC modules C carried on the COT 32.

[0025] The code information attachment unit 20 attaches first code information (e.g., a QR code 34a) including group head position information when grouping the IC modules C by production type to a position corresponding to the head of the tape-shaped base T. That is, the first code information is attached to a gap region P immediately before the first IC module C to be grouped by production type in the COT 32 moving in the transport direction A. For example, in FIG. 2, if the carrying regions F of adjacent IC modules C are for group M (preceding group) and group V (subsequent group), the first code information (QR code 34a) including group head position information of the subsequent group V is attached to the gap region Pa.

[0026] Similarly, the code information attachment unit 20 attaches second code information (e.g., QR code 34b) including group end position information when grouping the IC modules C by production type to an end corresponding position on the tape-shaped base T. That is, the second code information is attached to the gap region P immediately after the last IC module C to be grouped by production type in the COT 32 moving in the transport direction A. For example, in FIG. 2, when adjacent groups M and V are grouped, the second code information (QR code 34b) including group end position information of the preceding group M is attached to the gap region Pa.

[0027] 2 shows an example in which the first code information (QR code 34a) and the second code information (QR code 34b) are separately configured and attached side by side in the gap area Pa. In another embodiment, one QR code 34 may indicate the first code information indicating the group start position information and the second code information indicating the group end position information.

[0028] Another function of the QR code 34 is to provide manufacturing information that indicates additional information that can be used in the subsequent manufacturing process. As described above, different information is written to the multiple IC modules C of the COT 32 for each manufacturing type. For example, format information for company A, format information for company B, format information for a driver's license, format information for a passport, etc. Furthermore, when IC modules C classified by manufacturing type are actually used, information for individually identifying them is required. Therefore, the QR code 34 may be attached to a leading position of the tape-shaped base T when third code information (QR code 34c described later) including assigned information assigned to each IC module C is grouped. The third code information (assigned information) may be, for example, instruction information for specifying different information for each manufacturing type or serial information for individually identifying each IC module C (e.g., a serial number specifying the manufacturing lot, manufacturing date, etc.). The serial information may be generated, for example, by a host system of the control unit 12. The third code information (QR code 34c described later) attached to the leading position is attached to the same position as the first code information (QR code 34a). Therefore, the third code information (QR code 34c described later) may be attached alongside the first code information (QR code 34a), or one QR code 34 may include the first code information and the third code information.

[0029] Another function of the QR code 34 is to provide fourth code information including group information, i.e., information about the IC module C included in a group of COT32 wound on an individual reel CR (described later), when the COT32 is wound by each production type onto an individual reel CR and made ready for shipment. The fourth code information is provided by a QR code 34d (described later). The QR code 34d is attached to a position corresponding to the end of the COT32 when the COT32 is grouped. The fourth code information (QR code 34d) attached to the position corresponding to the end is attached in the same position as the second code information (QR code 34b). Therefore, the fourth code information (QR code 34d) may be attached next to the second code information (QR code 34b), or one QR code 34 may include both the second code information and the fourth code information. The information included in the QR code 34 is not limited to the above example, and may include information usable for manufacturing the COT32 or information usable when using the IC module C, as appropriate.

[0030] In the manufacturing process S3, the information reading unit 22 is controlled by the control unit 12. The information reading unit 22 can be configured with a known image recognition device, and captures an image of the QR code 34 with an imaging unit 22a (for example, a CCD camera, etc.), and performs known image processing. The information reading unit 22 acquires at least first code information (group start position information), third code information (assigned information), etc. as information contained in the QR code 34 acquired as a result of image analysis, and provides this information to the control unit 12. The control unit 12 controls the information writing unit 24 based on the acquired information of the QR code 34.

[0031] 3 is an exemplary schematic explanatory diagram showing an image of movement of the COT 32 used in the part manufacturing apparatus 10 in the manufacturing process S3, and an information writing process based on code information (QR code 34) attached to the COT 32. As described above, the manufacturing process S3 includes a QR code 34 reading process (not shown in FIG. 3) and an information writing process based on information contained in the read QR code 34.

[0032] 2, the control unit 12 provides the information writing unit 24 with the content of data to be written to the IC module C and write start position information (information on the IC module C where writing starts) based on the information on the QR code 34 provided from the information reading unit 22. Thereafter, the information reading unit 22 proceeds to detection processing of the next QR code 34 attached to the COT 32 (for example, QR code 34a indicating start position information or QR code 34c indicating attached information, etc.).

[0033] As described above, the sprocket 16a of the conveying unit 16 rotates in the direction of arrow B (clockwise). The teeth 16t formed on the outer periphery of the sprocket 16a sequentially engage with the sprocket holes 32a (see FIG. 2) of the COT 32, thereby accurately moving the COT 32 in the conveying direction A. Although not shown in FIG. 1, a position detection unit 36 ​​that detects the conveying position of the IC module C is disposed immediately before the information writing unit 24, as shown in FIG. 3. The position detection unit 36 ​​only needs to be able to detect the position of the IC module C, and various sensors such as an optical sensor, a capacitance sensor, or an ultrasonic sensor can be used. FIG. 3 shows an example in which an optical sensor composed of a light-emitting unit 36a and a light-receiving unit 36b is used.

[0034] The distance in the transport direction A between the position detection unit 36 ​​(light projecting unit 36a and light receiving unit 36b) and the information writing unit 24 is known. Therefore, based on the position detection result of the IC module C by the position detection unit 36, it is possible to accurately position the IC module C at the writing position of the information writing unit 24. As a result, the information writing unit 24 can accurately and efficiently write predetermined data to the IC module C to be written.

[0035] When the IC module C to be written has moved to the writing position, the information writing unit 24 uses a vertical drive mechanism (not shown) to lower the writing unit 24a toward the IC module C to be written. The information writing unit 24 then brings the writing probe 24P supported by the writing unit 24a into contact with the electrode portion of the IC module C, and writes data to the IC module C in accordance with instructions from the control unit 12. After writing the specified data, the information writing unit 24 raises and retracts the writing unit 24a, preparing to write data to the next IC module C. Note that while the present embodiment illustrates a contact-type information writing unit 24, a non-contact type may also be used. Furthermore, if the transport control (position control) of the COT 32 satisfies the positional accuracy required for data writing by the information writing unit 24, the position detection unit 36 ​​may be omitted.

[0036] The manufacturing process S4 includes a step of reading the QR code 34 and a step of separating the COT 32 based on the information contained in the read QR code 34.

[0037] The cutting position detection unit 26, which is included in the manufacturing process S4, is arranged downstream of the information writing unit 24. The cutting position detection unit 26 is controlled by the control unit 12. Like the information reading unit 22, the cutting position detection unit 26 can be configured with a well-known image recognition device, and captures an image of the QR code 34 with an imaging unit 26a (e.g., a CCD camera, etc.) and performs well-known image processing. The cutting position detection unit 26 acquires second code information (group end position information) included in the QR code 34 (QR code 34b) acquired as a result of image analysis, and provides the second code information to the control unit 12. The control unit 12 controls the cutting unit 28 based on the information of the acquired QR code 34b.

[0038] Based on the information of the acquired QR code 34b, the control unit 12 provides the group end position information in the COT 32 to the cutting unit 28. Thereafter, the cutting position detection unit 26 proceeds to the detection process of the next QR code 34b (end position information) attached to the COT 32.

[0039] The cutting unit 28 separates the COT32 into groups for each manufacturing type defined by the QR code 34a (group start position information) and the QR code 34b (group end position information). That is, the cutting unit 28 cuts the COT32 at a position immediately after the last IC module C of the group (a position immediately after the QR code 34b (end position information) and the QR code 34d (group information)) in accordance with the QR code 34b (end position information). The cutting unit 28 waits at a position above the COT32 while the COT32 is being transported. Then, when the movement of the COT32 reaches the cutting position based on the QR code 34b (end position information), the cutting unit 28 lowers the blade support unit 28a toward the COT32 and cuts the COT32 at the group end position with the blade 28t. After cutting is complete, the blade support unit 28a is raised to prepare for cutting at the next group end position.

[0040] A sensor device similar to the position detection unit 36 ​​may be disposed near the cutting position detection unit 26 to acquire the exact position of the IC module C. The second code information (QR code 34b) indicating the group end position information may be acquired by the information reading unit 22 in the manufacturing process S3 together with the first code information (QR code 34a) indicating the group start position information. In this case, the cutting position detection unit 26 may be omitted.

[0041] The COT winding section 30 included in the manufacturing process S5 winds the COT 32 for each manufacturing type onto individual reels CR (empty reels) so that the COT 32 can be shipped individually.

[0042] The COT winding unit 30 supports a disk-shaped individual reel CR and rotates it clockwise in FIG. 1 using a drive source (e.g., a motor, not shown) to wind up a COT 32 carrying an IC module C with predetermined data written thereon. The center of the individual reel CR is engaged with the leading position of the COT 32 cut by the cutting unit 28 for each production type. At this time, the group end position of the COT 32 has not yet reached the cutting unit 28, which is the previous process. Therefore, the COT 32 can be smoothly wound onto the individual reel CR while maintaining a predetermined tension. Finally, the group end position of the COT 32 at the cutting unit 28 becomes the leading position for unwinding the COT 32 on the individual reel CR, completing a product reel CRA wound with a shippable COT 32. The completed product reel CRA is removed from the COT winding unit 30 and can be shipped. The next individual reel CR is then attached to the COT winding unit 30, allowing the next COT 32 to be wound. By producing product reel CRA for each production type, the product reel CRA becomes easier to carry and handle, and also easier to store and manage.

[0043] As described above, when the COT32 are grouped by production type, a QR code 34 containing information about the IC module C included in the group of COT32 wound on the individual reel CR, i.e., the fourth code information (QR code 34d), is attached to the end corresponding position of the COT32. Therefore, by reading and processing the QR code 34d at the leading position of the COT32 being unwound from the product reel CRA, it is possible to easily and reliably confirm the type of IC module C of the COT32 wound on the product reel.

[0044] As described above, in the component manufacturing apparatus 10 of this embodiment, code information (e.g., QR code 34) indicating additional information usable in the manufacturing process for each manufacturing type is attached to the COT 32 (tape-shaped base T), and the COT 32 is manufactured based on the information in the QR code 34. Therefore, after the QR code 34 is attached, the work of checking the manufacturing details by the manager W or the like can be alleviated or omitted, and human error can be easily and reliably reduced in the manufacturing of IC modules C using the COT 32. Furthermore, it is possible to provide COT 32 (semiconductor-carrying components) that can easily and reliably reduce human error in the manufacturing of IC modules C.

[0045] 4 to 7 are exemplary schematic explanatory diagrams showing attachment patterns (attachment forms) of code information (QR code 34) attached to the COT 32 used in the part manufacturing apparatus 10. FIG.

[0046] 4 is an exemplary and schematic explanatory diagram showing the simplest attachment pattern in which first code information (QR code 34a) including group start position information and second code information (QR code 34b) including group end position information are attached to a tape-shaped base T when COTs 32 are grouped using a QR code 34. In this case, the QR codes 34 are attached to gap regions P in the transport direction A of the IC modules C aligned and arranged on the tape-shaped base T.

[0047] Specifically, a QR code 34a is attached to a gap region P, which is the corresponding start position when COT32-shaped IC modules C are grouped. Similarly, a QR code 34b is attached to a gap region P, which is the corresponding end position when COT32-shaped IC modules C are grouped. The corresponding start and end positions when grouping, i.e., the attachment positions of the QR codes 34a and 34b, are specified by the control unit 12 based on the production plan. Then, by reading the QR code 34a with the imaging unit 22a of the information reading unit 22, the coordinates of the group start position on the component manufacturing apparatus 10 can be easily and accurately recognized. Similarly, by reading the QR code 34b with the imaging unit 22a, the coordinates of the group end position on the component manufacturing apparatus 10 can be easily and accurately recognized. In this case, a QR code 34a containing group start position information of the next group is attached after the QR code 34b containing the group end position information.

[0048] In Fig. 4, the IC modules C are carried on the tape-shaped base T in two rows in the conveying direction A, and QR codes 34 (QR codes 34a and 34b) are arranged in each row. In another embodiment, regardless of the number of rows of IC modules C, one QR code 34 corresponding to each group start position and group end position may simply be attached. Also, as shown in Fig. 2, the QR codes 34a containing group start position information and the QR codes 34b containing group end position information may be attached side by side in the width direction of the tape-shaped base T (a direction perpendicular to the conveying direction A). In this case, the QR code 34a indicates group start position information of a group upstream of the QR code 34a in the conveying direction, and the QR code 34b indicates group end position information of a group downstream of the QR code 34b in the conveying direction.

[0049] 5 is an exemplary and schematic explanatory diagram showing an example of an attachment image in which third code information (QR code 34c) including assigned information assigned to each IC module C is attached to a corresponding leading position on the tape-shaped base T when grouping, in addition to the attachment pattern of the QR codes 34 shown in FIG. 4. In this case, the QR code 34c is attached adjacent to the first code information (QR code 34a) including group leading position information. In FIG. 5, the QR code 34c is attached so as to be read before the QR code 34a when the COT 32 is transported, but the QR code 34a may be attached so as to be read before the QR code 34c.

[0050] By reading QR code 34a and QR code 34c with imaging unit 22a of information reading section 22, it is possible to easily and accurately recognize the coordinates of the group head position in component manufacturing apparatus 10, as well as the content of data to be written to IC modules C carried after the group head position. This makes it possible to prevent errors in writing data to IC modules C.

[0051] 5, as in FIG. 4, the IC modules C are carried on the tape-shaped base T in two rows in the conveying direction A, and QR codes 34 (QR codes 34a, 34c, and 34b) are arranged in each row. In another embodiment, regardless of the number of rows of IC modules C, the QR codes 34a and 34c may simply be attached at the beginning of the group, and one QR code 34b may be attached at the end of the group. Also, as shown in FIG. 2, the QR code 34a containing the group beginning position information and the QR code 34b containing the group end position information may be attached side by side in the width direction of the tape-shaped base T (the direction perpendicular to the conveying direction A). In this case, a single QR code 34 may be used that indicates the information in the QR code 34a and the information in the QR code 34c.

[0052] The attachment pattern of the QR code 34 in Fig. 6 is a modified example of the attachment pattern of the QR code 34 shown in Fig. 5. In the attachment pattern of the QR code 34 in Fig. 6, first attachment information (QR code 34c1) is attached together with group start position information (QR code 34a), and second attachment information (QR code 34c2) is attached between the QR code 34a including the group start position information and the QR code 34b including the group end position information. In the attachment pattern of the QR code 34 in Fig. 5, basically the same information (for example, data for company A) other than the serial number is written to the IC module C in the group in accordance with the attachment information (QR code 34) attached together with the group start position information (QR code 34a). On the other hand, in the case of the attachment pattern of the QR code 34 in FIG. 6, for example, data of Company A's pattern a is first written by the first attachment information (QR code 34c1) read together with the QR code 34a including the group start position information, and then when the second attachment information (QR code 34c2) is read, the writing of data switches to Company A's pattern b. In other words, it becomes possible to manufacture IC modules C in which different data is written within the same group. In this case, it becomes possible to easily customize the IC module C, which contributes to improving the product value. Note that the number of attachment information (QR code 34c) attached between the QR code 34a and the QR code 34b can be changed as appropriate, and two or more types of attachment may be used.

[0053] Fig. 7 is a perspective view showing the detailed configuration of a product reel CRA. In Fig. 7, a QR code 34b containing group end position information and fourth code information (QR code 34d) containing group information of the IC modules C included in the group are attached to a leading region Pt (gap region P before cutting) of the COT 32 unwound from the product reel CRA. Therefore, when managing or using the product reel CRA, detailed information of the IC modules C carried by the COT 32 wound on the product reel CRA can be easily and accurately obtained by reading the QR code 34d attached to the leading region Pt of the COT 32. As a result, it is possible to prevent incorrect management of the IC modules C or incorrect use during use.

[0054] As described above, the QR code 34 can contain a variety of information (data). Attaching the QR code 34 to the COT 32 (tape-shaped base T) can eliminate or reduce the need for various checking tasks in the manufacturing process of the COT 32, contributing to the suppression and prevention of human error. Furthermore, a combination of multiple QR codes 34 can be attached to the COT 32 (tape-shaped base T), making it easy to increase the amount of information that can be attached.
