    摘要： A method of producing a semiconductor device by dividing a semiconductor wafer into separate pieces of semiconductor chips. This method includes forming a groove with a pattern according to an outer contour of a desired semiconductor chip, holding the semiconductor wafer by a wafer holding mechanism, grinding a back surface of the semiconductor wafer held by the wafer holding mechanism, detecting opening of a bottom face of the groove during the back surface grinding process to determine timing for finishing the back surface grinding. The opening of the groove can be detected by means of a light sensor for detecting light passing through the groove or a microwave sensor for detecting a microwave passing through the groove. In addition, it is possible to suck air inside the groove so as to detect the opening of the groove by a pressure rise in the air inside the groove.

    摘要： Upon receiving an encipherment command, an enciphered authentication data generation circuit generates an enciphered authentication data based on a basic authentication data including a random number portion using an encipherment rule. The encipherment rule changes according to the number of supplied encipherment commands. A transmission circuit 7 transmits the enciphered authentication data. A reception circuit 9 receives the enciphered authentication data transmitted from a second device 300. A prohibition command output circuit 11 determines whether the enciphered authentication data transmitted from the second device 300 matches with an enciphered authentication data that would be generated if the same number of encipherment commands were supplied to an enciphered authentication data generation circuit of a first device 200, and outputs a prohibition command to prohibit a transmission of the data to be transmitted when the determination result is negative.

    摘要： An IC card 3 has an ID number ID0, for permitting itself to be identified, stored in memory provided therein. The IC card also has additional ID numbers ID1 to IDn stored in memory areas 17-1 to 17-n that are secured therein so as to be allocated to the individual providers that manage the reader/writers with which the IC card communicates. These additional ID numbers ID1 to IDn are used to prevent unauthorized use of the IC card, and are issued so as to be unique to the IC card by the individual providers that use the memory areas 17-1 to 17-n. Thus, the additional ID numbers ID1 to IDn differ from one IC card to another.
