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 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:
The invention relates to a method for marking a solar cell, comprising the following steps: Providing a solar cell substrate (1 ); Selecting an identification pattern for identifying the solar cell substrate (1 ) during process steps of a manufacturing process for the solar cell and / or for tracing back the solar cell substrate (1 ) after assembly of the solar cell in a solar cell module; Forming an etch resist layer (3) on a surface (2) of the solar cell substrate (1 ); Etching the surface (2) of the solar cell substrate (1 ) with an etchant, whereby the etch resist layer (3) is formed in such a way that a pattern region (4) of the surface (2) in the shape of the identification pattern is protected from the etchant. Furthermore, the invention relates to a solar 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.
