摘要:
The invention relates to a module having a first integrated circuit and a second integrated circuit which are arranged on separate substrates, having a first output terminal and a second output terminal to which the first and second integrated circuits are respectfully connected in a parallel manner, and having a first selection terminal and a second selection terminal which are mutually separate and are connected to the first and second integrated circuits, respectively. A test circuit is provided in each of the integrated circuits to generate an error signal depending on whether an error occurred during a test operation, and an output circuit is provided in each of the integrated circuits to select the first output terminal or the second output terminal, depending on a selection signal that is applied to the respective selection terminal, for the purpose of outputting a state that indicates the error.

One embodiment of the invention provides a calibration device for the calibration of a tester channel of a tester device to which integrated components on a substrate wafer can be contact-connected for testing with electrical signals. The calibration device includes a connecting device and a planar contact carrier with a first contact area and a second contact area insulated from the first contact area, which can be electrically connected via the connecting device, the connecting device being suitable for connecting the first and second contact areas to the tester device, the first contact area being generally surrounded by the second contact area, so that, when a needle card connected to the tester device is placed onto the contact carrier of the calibration device, one of the contact-connecting needles of the needle card which is connected to the tester channel to be calibrated is placed onto the first contact area and a plurality or all of the further contact-connecting needles of the needle card at tester channels that are not to be calibrated are placed onto the second contact area.

For a selection of semiconductor chips stacked on top of one another, the invention includes leading through selection contact points of one chip on a rear side thereof and connecting them to corresponding selection contact points of the other semiconductor chip. Programmable input amplifiers are programmed to be transmissive or blocking through fuses/antifuses so that selection signals applied to the selection contact points either activate or block functional elements only of one or only of the other semiconductor chip. As a result, simple stacking of identically prefabricated semiconductor chips is made possible.

An electronic component has a plurality of chips which are stacked one above the other and contact-connected to one another. To form this component, a first planar chip arrangement is provided with the functional chips spaced apart from one another in a grid and with a filling material in the spaces between the chips to form an insulating holding frame that fixes the chips, the frame has chip-dedicated contact-connecting elements that serve for the electrical contact-connection to another chip of another chip arrangement and each chip has dedicated electrically conductive strips. At least one additional planar chip arrangement is formed by the same method as the first planar chip arrangement and is then stacked on the first planar chip arrangement so that the two chip arrangements lie one above the other and the respective contact-connecting elements of the two chip arrangements are connected to one another for electrical chip-to-chip contact-connection. Subsequently, each of the components, which comprise a stack of chips, is separated from the assembled stack of chip arrangements.

A pointer generation circuit, in accordance with the invention, includes a clock for providing a clock cycle, and a shift register with a plurality of latches for storing data bits. A first latch receives a flag bit upon a first clock cycle of the clock. A switch transfers the flag bit to the shift register on the first clock cycle. The switch connects a last latch to the first latch after the flag bit is transferred to the shift register. The flag bit is transferred to a next latch, wherein the next latch for the last latch is the first latch, at each consecutive clock cycle thereby generating pointer signals in accordance with the clock cycle and the data bits stored in the latches.
