A terminal metallization (8) is applied onto and structured on a layer structure on the upper side of the component, the terminal metallization is applied on the upper side of an insulating layer (7) with an opening on a metallization (6) provided for electrical connection. By filling a hole produced in a covering dielectric with metal, a contact rod (12) seated on this terminal metallization (8) is formed. This contact rod is resiliently movable in a surrounding opening (14) of the component on the free part of the terminal metallization (8) anchored in the layer structure. This enables the reversible contacting of the component to a further component arranged vertically thereto, whereby the planar upper sides lying opposite one another can be brought into intimate contact because the contact rod (12) pressed against a contact (15) of the other component is pressed back into the opening (14) and an adequately firm connection of the contacts is achieved by the spring power of the terminal metallization (8).

An integrated semiconductor circuit has a regular array of logic function blocks (L) and a regular array of wiring zones (X) corresponding thereto. The wiring lines in at least one wiring layer of a wiring zone (X) are realized as line segments that are continuous within the wiring zone and are interrupted at zone boundaries. Furthermore, the semiconductor circuit comprises driver cells that surround a logic cell of the logic function block in an L-shaped manner.

A system and method for processing data is disclosed. In one embodiment, a data moving processor comprises a code memory coupled to a code fetch circuit and a decode circuit coupled to the code fetch circuit. An address stack is coupled to the decode circuit and configured to store address data. A general purpose stack is coupled to the decode circuit and configured to store other data. The data moving processor uses data from the general purpose stack to perform calculations. The data moving processor uses address data from the address stack to identify source and destination memory locations. The address data may be used to drive an address line of a memory during a read or write operation. The address stack and general purpose stack are separately controlled using bytecode.
摘要:
A method and apparatus for the reversible contacting of a semiconductor circuit level to assist in performing a function test. The apparatus includes a testing head having test points arranged at a test side lying opposite the contact surfaces of a semiconductor circuit level. The test points are formed of liquid contacts in recesses in the test side of the testing head wherein the liquid contacts form menisci that project beyond the surface of the testing head. The recesses, in turn, are provided for metallizations which are connected to electrically-conductive leads. In addition, the surface may be provided with a roughening or with etched trenches.

In order to test digital modules with functional elements, these are divided into test units (3) which respectively have inputs and outputs. Alternating test patterns are applied to the inputs of the test unit (3), and the test responses resulting from this are evaluated at the outputs of the test unit (3). The effect is then encountered that changes at each of the inputs of a test unit (3) do not all affect a particular output of this test unit (3). For every output of the test unit (3), it is possible to define a cone (5) whose apex is formed by the particular output of the test unit (3) and whose base comprises the inputs of the test unit (3) where, and only where, changes affect the particular output. According to the invention, the test pattern to be applied to the inputs of the test unit (3) is constructed of sub-patterns, whose length is in particular
