  • Publication number: 20080314715
    Abstract: A security element comprises at least one oscillating circuit (O1-On) and a digital signature (2). Each oscillating circuit (O1-On) comprises a capacitor (C1-Cn) as resonance frequency setting element wherein the capacitor (C1-Cn) consists of two electrodes (8, 10) which are spaced apart from each other and a dielectric (9) that is sandwiched between the two electrodes (8, 10). The capacitor (C1-Cn) of each oscillating circuit has a random capacitance value which randomness is caused by a non-uniform thickness (d) of the dielectric (9) and/or by an inhomogeneous dielectric material. The digital signature (2) comprises reference values indicative for the resonance frequencies (f1-fh) of the oscillating circuits wherein the reference values are digitally signed with a secret key.

  • Publication number: 20080285333
    Abstract: The electric device (100) according to the invention has a resistor comprising a layer (7, 107) of a phase change material which is changeable between a first phase with a first electrical resistivity and a second phase with a second electrical resistivity different from the first electrical resistivity. The phase change material is a fast growth material. The electric device (100) further comprises a switching signal generator (400) for switching the resistor between at least three different electrical resistance values by changing a corresponding portion of the layer (7, 107) of the phase change material from the first phase to the second phase.

  • Publication number: 20080230802
    Abstract: A semiconductor device with a heterojunction. The device comprises a substrate and at least one nanostructure. The substrate and nanostructure is of different materials. The substrate may e.g. be of a group IV semiconductor material, whereas the nanostructure may be of a group III-V semiconductor material. The nanostructure is supported by and in epitaxial relationship with the substrate. A nanostructure may be the functional component of an electronic device such as a gate-around-transistor device. In an embodiment of a gate-around-transistor, a nanowire (51) is supported by a substrate (50), the substrate being the drain, the nanowire the current channel and a top metal contact (59) the source. A thin gate dielectric (54) is separating the nanowire and the gate electrode (55A, 55B).

  • Patent number: 7326631
    Abstract: Consistent with an example embodiment, a method of manufacturing a semiconductor device comprises MOS transistors having gate electrodes formed in a number of metal layers deposited upon one another. Active silicon regions having a layer of a gate dielectric and field-isolation regions insulating these regions from each other are formed in a silicon body. Then, a layer of a first metal is deposited in which locally, in a part of the active regions, nitrogen is introduced. On the layer of the first metal, a layer of a second metal is then deposited, after which the gate electrodes are etched in the metal layers. Before nitrogen is introduced into the first metal layer, an auxiliary layer of a third metal permeable to nitrogen is deposited an the first metal layer. Thus, the first metal layer can be nitrided locally without the risk of damaging the underlying gate dielectric.

  • Patent number: 7309907
    Abstract: The semiconductor device (11) of the invention comprises a circuit that is covered by a passivation structure. It is provided with a first security element (12) that comprises a local area of the passivation structure and which has a first impedance. Preferably, a plurality of security elements (12) is present, whose the impedances differ. The semiconductor device (11) further comprises measuring means (4) for measuring an actual value of the first impedance, and a memory (7) comprising a first memory element (7A) for storing the actual value as a first reference value in the first memory element (7A). The semiconductor device (11) of the invention can be initialized by a method wherein the actual value is stored as the first reference value. Its authenticity can be checked by comparison of the actual value again measured and the first reference value.

  • Patent number: 7307267
    Abstract: The electric device (1, 100) has a body (2, 102) having a resistor (7, 107) comprising a phase change material being changeable between a first phase and a second phase. The resistor (7, 107) has a first electrical resistance when the phase change material is in the first phase and a second electrical resistance, different from the first electrical resistance, when the phase change material is in the second phase. The body (2, 102) further has a heating element (6, 106) being able to conduct a current for enabling a transition from the first phase to the second phase. The heating element (6, 106) is arranged in parallel with the resistor (7, 107).

  • Patent number: 7119353
    Abstract: The electric device (100) has a body (102) having a resistor (107) comprising a phase change material being changeable between a first phase and a second phase. The resistor (107) has a first electrical resistance when the phase change material is in the first phase, and a second electrical resistance, different from the first electrical resistance, when the phase change material is in the second phase. The phase change material constitutes a conductive path between a first contact area and a second contact area. A cross-section of the conductive path is smaller than the first contact area and the second contact area. The body (102) may further have a heating element 106 being able to conduct a current for enabling a transition from the first phase to the second phase. The heating element (106) is preferably arranged in parallel with the resistor (107).
