摘要:
Embodiments of devices and method for detecting semiconductor substrate thickness are disclosed. In an embodiment, an IC device includes a semiconductor substrate, a charge emitter embedded in the semiconductor substrate and configured to produce an electrical charge in the semiconductor substrate and a charge sensor embedded in the semiconductor substrate and configured to generate a response signal in response to the electrical charge produced in the semiconductor substrate. The magnitude of the response signal depends on the thickness of the semiconductor substrate.

Embodiments of an electronic device are disclosed. In one embodiment, the electronic device includes a circuit board, a central processing unit (110), an RFID IC (112), and a physically secure communications channel (116). The circuit board includes a radio frequency antenna (114), the CPU is connected to the circuit board and includes a CPU-to-RF identification (RFID) interface (130) that does not support a digital security measure which requires asymmetric key cryptography, the CPU being enclosed within a package. The RFID IC is connected to the RF antenna and has an RFID-to-CPU interface that does not support a digital security measure which requires asymmetric key cryptography. The RFID IC also has non-volatile memory that stores configuration data for configuring the electronic device. The physically secure communications channel connects the CPU-to-RFID interface to the RFID-to-CPU interface and the physically secure communication channel is protected from physical access by a structural barrier.

Dans un dispositif connectable portable à microcircuit(s), utilisant des fils de connexion soudés pour le câblage électrique du microcircuit au connecteur, au moins un fil de connexion w 4 d'un plot p 4 est formé de manière à faire un détour l 4 passant au-dessus de la face active du microcircuit. On obtient ainsi un dispositif anti-intrusion simple et efficace à empêcher une attaque en faute ou de type EMA.
摘要:
The microcomponent (1) has a first wafer (2), equipped with multiple electrical connection pins (5), a second wafer (7), equipped with multiple electrical connection pads (8), intended to cooperate with the electrical connection pins (5) of the first wafer (2). The second wafer (7) has multiple first interconnection pins (10), formed on the electrical connection pads (8) of the second wafer (7), positioned facing the electrical connection pins (5) of the first wafer (2) and coming into contact with each other by nesting. An interconnection process for the first (2) and second (7) wafers of the microcomponent (1) consisting of at least the stages of the formation of the pins (5) of the first wafer (2), for example by electro-chemical growth, and of the formation of the pins (10) of the second wafer (7), for example by chemical growth.
摘要:
Two or more semiconductor packages (14, 12) are stacked with an intervening element (16, 43) that is positioned between within an area surrounded by conductive bumps (28) of a bottom surface of the overlying package. Different shapes of the intervening element (16, 43) are used depending upon how many sides of the bottom surface have conductive bumps. In one form (Fig. 7) the intervening element extends laterally from the stack and is bent downward to contact or extend through an underlying substrate (30). Contact to the intervening element at the backside of the substrate may be made. In another form (Fig. 13) the intervening element is bent upward for enhancing thermal properties. The intervening element (16, 43) is adhesive to prevent non-destructive removal of the packages thereby adding increased security for information contained within the packages. Selective electrical shielding between packages is also provided.
