Abstract:
The invention relates to a chipcard arrangement with a card-like support, in which a recess is provided, with at least two superimposed semiconductor chips (4, 5) arranged therein. Said chips exchange electrical signals and/or energy, with each other, by means of electrically conducting connectors, whereby the at least two semiconductor chips (4, 5) together have a minimum size of from 20 to 25 mm and the electrically conducting connection is achieved by means of a three-dimensional wiring in the semiconductor chip.
Abstract:
A floating gate cell is used as a clock whereby the charging process is delayed by the application of a sufficiently low charging voltage until a predetermined threshold voltage is reached. A particularly thin tunnel oxide layer can be provided in order to bring about a gradual discharge of a charged cell. Preferably, the floating gate electrode (5)is connected to the control gate electrode (16) of a second cell, which then delays the charging of the floating gate electrode (15) of the second cell.
Abstract:
The invention relates to a circuit comprising a first substrate (1) which has an integrated circuit (4) in a first surface (3) and a second surface (2) opposite the same, and a second substrate (9) which has a sensor (7) on one surface. Said second substrate (9) is adhesively connected to the first substrate (1) in such a way that the surface of the second substrate (9) comprising the sensor (7) faces one of the two surfaces (2, 3) of the first substrate (1). It can thus be determined whether the arrangement consisting of the first and second substrate is divided or has been divided.
Abstract:
A method for fabricating a wiring which runs at least piecewise in a substrate. At least one conductive connection runs in the semiconductor substrate and at least one conductive connection runs on the semiconductor substrate being provided. The semiconductor component enables applications in which high security against external manipulations is important.

Abstract:
A vertical integrated circuit has at least two integrated part-circuits (1,2) arranged lying over one another, and which are interconnected so that on each of the part-circuits (1,2) is formed a digital memory device (4,6) and that a stored byte is split up into given bit-groups and, in each case, one bit-group of a byte is stored in each digital memory device (4,5) of the integrated part-circuit (1,2). At least one data-line (5) runs from the upper integrated part- circuit (1) through the latter to the lower integrated part- circuit (2), and the digital memory devices (4,6) of the different integrated part-circuits (1,2), are arranged directly lying over one another.
