DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an IC card which can be used as a contact type IC card or a non-contact type IC card with one IC chip, and particularly to all types of IC cards such as quiche cards, credit cards and point cards. The present invention relates to a contact / non-contact type IC card applicable to a magnetic card and an IC card.

[0002]

2. Description of the Related Art Conventionally, in the fields of credit cards, ID cards, cash cards, and the like, as a card replacing a magnetic card, an IC module including a semiconductor memory such as a microprocessor, RAM, and ROM is mounted on a card material. A so-called IC card has been developed because of its extremely large information recording capacity and high security. These IC cards are roughly classified into a type in which reading is performed by a contact type with a reader and a type in which reading is performed by a non-contact type. The contact type performs power supply and information communication by directly contacting and connecting a reader-side terminal to an external terminal exposed on the surface of the card. Most current IC card types fall into this category. In the reading of this contact-type card, the error rate for a good card is extremely low, but if the external terminals are dirty or damaged by abrasion, electrical conductivity may be lost and reading may not be possible. . Further, in a dry environment, the surface of the card is easily charged with static electricity, which causes a reading error.

Therefore, in recent years, an IC card using a non-contact type IC module composed of a memory IC chip and a coil having a function as a power supply and communication antenna has been developed. The non-contact type IC module used for this card does not need to expose the communication terminal to the card surface when making the card because the communication is performed in a non-contact manner. Don't worry.

Further, at present, a combined IC card (contact type IC card) combining the above-mentioned non-contact type IC card and contact type IC card to realize a non-contact function and a contact function with one chip.
C module and a communication antenna coil installed in one medium and integrated) have been proposed. That is,
Combine the ease of use of contactless type with the security of contact type to realize convenient applications that are suitable for, for example, fee payment operation and billing in bank ticket systems, bank transactions, various identity confirmation operations, etc. Is a composite IC card for the following purpose.

This composite IC card varies depending on the form of the IC module. For example, as shown in FIG. 5, an external connection terminal 31 is provided on a substrate 32, and both ends are provided for connection with the external connection terminal. Through holes 33, 33,
Wiring patterns 34, 34 are provided below the through holes, and although not shown, an IC chip and this IC
The chip and the wiring pattern are wire-bonded, and this part is resin-molded 35, and the convex-shaped IC module 3 having connection terminals 12 and 12 disposed on the lowermost surface thereof.
0, the antenna coil 15 is embedded,
Alternatively, the IC module 30 is formed by injection molding.
Is formed, and the connection terminals 22 and 22 of the antenna coil are exposed on the bottom surface thereof. The connection terminals 22 and 22 of the antenna coil and the connection terminals 12 and
This is a method of electrically connecting 12 members by solder bumps 38, 38 and the like.

[0006]

However, exposing the connection terminals on the antenna coil side to the bottom surface of the concave portion of the card base material requires strict precision, so that counterboring and other processing techniques are very difficult, so that manufacturing is difficult. Is not easy. Further, when a non-contact type IC card is used together with a magnetic card or a contact type IC card (including a composite card), the thickness and shape of the card are limited by the standard, so that the size of the antenna coil is limited ( Communication distance is limited), embossing cannot be performed depending on the antenna coil size,
There is a problem that the physical properties are different due to the built-in coil. In addition, the non-contact type IC card alone has a problem that it operates irrespective of the user's intention and malfunctions due to other radio waves.
