Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a semiconductor product on which a special code is displayed.
[0002]
[Prior art]
Conventionally, in order to transmit information about a semiconductor product to a user or the like, a character name, a symbol, a symbol, They were shipped with some printing (marking) such as lines, dots, and logo marks. Hereinafter, conventional display information means will be described.
[0003]
FIG. 4 shows a conventional diode (semiconductor product) 1. As shown in FIG. 4, the semiconductor product 1 displays, on the product body 2, a cathode band 3 indicating the direction of the product, alphabetical characters 4 of “G” and “A”, and a numeral 5 of “1”. ing. Here, the letter 4 of "A" indicates January in the month of manufacture, the letter 4 of "G" indicates a general-purpose product, the number 5 indicates that it is the first product, and "G1" is the product. Since the name is shown, the indication on the surface of the product main body 2 indicates the product use direction, the product name, and the month of manufacture.
[0004]
However, recently, semiconductor products tend to be miniaturized, so that the number of characters that can be displayed on the semiconductor products has been reduced, and examples of using symbols, dots, lines, and the like that are easy to identify have been found.
[0005]
On the other hand, from the viewpoint of customer service, more detailed display of manufacturing information (improvement of lot traceability) has been required, and it has been difficult to achieve both.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of such circumstances, and at least a part of all characters is displayed on a product body using a special code, and information is given to the product body, so that one character has a plurality of pieces of information. Can increase the amount of information with the same number of characters, thereby reducing the number of displayed characters and reducing the printing time, or displaying special codes that can increase the amount of displayed information and improve lot traceability. The purpose is to provide the product.
[0007]
[Means for Solving the Problems]
A semiconductor product on which a special code according to the present invention is displayed is characterized in that at least a part of every character is displayed on the product main body using the special code, and information is provided on the product main body. That is, in the present invention, as a means for increasing the amount of display information, it is effective to introduce a special code (for example, a one- or two-dimensional bar code, an original code). The addition leads to a decrease in throughput. Therefore, the amount of information can be increased without increasing the number of displays by using some of the conventionally existing symbols, dots, lines, and the like as the special codes.
[0008]
In the present invention, the character includes a character, a number, a picture, a figure, a line, a dot, a logo mark, or a surface treatment on a product body intentionally added by a manufacturer. Here, as a method of printing (marking) a character on a product, a conventionally used method such as printing, ink mark, and laser mark can be exemplified, but is not limited thereto.
[0009]
In the present invention, the special code means all characters that have a specific meaning in the display, except for the case where the display itself has a meaning. Here, “the display itself has a meaning” indicates Japanese, English, numerals, and the like. Examples of the special code include the following examples.
[0010]
-Barcode-Two-dimensional barcode: Specifically, a stack-type two-dimensional code as shown in Fig. 5 or a matrix-type two-dimensional code (CPCCode) as shown in Fig. 6.
-Dot display: For example, FIG.
"A", "b", "c" ... For example, "a" = 1, "b" = 2, "c" = ...
-"1", "2", "3" ... For example, "1" = Japan, "2" = Korea, ...
"-", "|", "/" ... For example, "-" = 1990, "|" = 1991, "/" = 1992
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a semiconductor product on which a special code according to each embodiment of the present invention is displayed will be described with reference to the drawings.
[0012]
(Example 1)
Please refer to FIG. 1 and FIG. Here, FIG. 1 is a plan view of the semiconductor product according to the first embodiment, and FIG. 2 is an explanatory diagram of a special code used for displaying the semiconductor product of FIG. Reference numeral 11 in FIG. 1 indicates a diode as a semiconductor product. On the main surface of the product body 12 of the semiconductor product 11, a character 13 as a character indicating "G" and a numeral 14 indicating "1" as a character are displayed. Here, the character 13 indicates a general-purpose product, and “G1” indicates a product name. The shape of the product main body 12 is, for example, 2.6 mm (horizontal) × 1.6 mm (vertical). Further, a two-dimensional code 15 as a special code shown in FIG. 2 is displayed on the main surface of the product main body 12, for example, by printing. Here, the two-dimensional code 15 corresponds to the cathode band in FIG.
[0013]
As shown in FIG. 2, the two-dimensional code 15 has an L-shaped full dot portion, and has a size of 9 × 5 dots. In the display, a circle is defined as one cell, and 1 cell = 1 character (4 bits of binary display (0 to F)) and Total: 8 characters are displayed. The code in FIG. 2 represents '12345678'. Further, the two-dimensional code 15 can be identified by an eight-digit display of (9 × 5 dots), such as a production date. An eight-digit number is automatically issued and displayed to display an eight-digit number. The production equipment, date of production, etc. can be found.
[0014]
As described above, the semiconductor product 11 according to the first embodiment displays at least a part of all the characters on the product main body 12 using the two-dimensional code 15 and gives information to the product main body 12 so that a plurality of characters are provided for one character. Information can be provided. Therefore, it is possible to increase the amount of information with the same number of characters as in the conventional semiconductor product, thereby reducing the number of display characters and reducing the printing time, or increasing the amount of display information and improving the lot traceability.
[0015]
In the first embodiment, a case where a part of a character is displayed by a two-dimensional code (special code) is described. However, the present invention is not limited to this, and another character may be displayed by a special code.
[0016]
In the first embodiment, the case where the semiconductor product is a diode has been described. However, the present invention is not limited to this and can be applied to all semiconductor products such as ICs.
