Referring to fig. 7, a schematic structural diagram of a semiconductor unit device according to still another embodiment of the present invention is shown. Referring to fig. 8, a schematic structural diagram of a semiconductor unit device according to still another embodiment of the present invention is shown. The structure of the semiconductor unit device will be described with reference to fig. 7 and 8.

In a specific implementation, the semiconductor unit device 10 may include a high-level output unit 11, a low-level output unit 12, and a metal interconnection line 13. The metal interconnection line 13 is provided with a configurable via structure 14, and the position of the configurable via structure 14 is configurable, so as to connect the metal interconnection line to a selected object by configuring the position of the configurable via structure 14.

In an implementation, the selected object may be any one of the high level output unit 11 and the low level output unit 12.

In some embodiments of the present invention, as shown in fig. 7, the configurable via structure 14 may connect the metal interconnection line 13 to the high-level output unit 11, so that the configurable via structure 14 may conduct the metal interconnection line 13 with the high-level output unit 11 to output a high level.

In other embodiments of the present invention, as shown in fig. 8, the configurable via structure 14 may connect the metal interconnection line 13 to the low-level output unit 12, so that the configurable via structure 14 conducts the metal interconnection line 13 with the low-level output unit 12 to output a low level.

In an embodiment of the present invention, the configurable VIA structure 14 may include a VIA (VIA1) and a conductive plug filled in the VIA.

When the output logic of the semiconductor unit device 10 needs to be changed after tape-out, for example, when the output logic is changed from a high level to a low level, only one mask layer needs to be modified, the configurable via structure 14 conducts the metal interconnection 13 with the high level output unit 11, and the configurable via structure 14 conducts the metal interconnection 13 with the low level output unit 12, that is, the mask layer is modified, through the position of the via structure 14, the selected object conducted with the metal interconnection 13 is the low level output unit 12 or the high level output unit 11, so as to change the output logic.

As can be seen from the above, the semiconductor unit device includes a high-level output unit, a low-level output unit, and a metal interconnection line, and the metal interconnection line is provided with a configurable via structure, and since the location of the via structure is configurable, the metal interconnection line can be connected to a selected object, for example, the via structure can be used to connect the metal interconnection line to the high-level output unit, or connect the metal interconnection line to the low-level output unit, and use the metal interconnection line as an output pin, so that compatibility of the output pin can be achieved. If the output logic needs to be changed after tape out, because the output pins are compatible, ECO winding is not needed before and after ECO, and the change of the output logic can be realized by changing a photomask layer to reconfigure the position of the through hole structure, so that the ECO cost can be reduced.

In a specific implementation, the high level output unit 11 may adopt a logic unit TIEHI for outputting 1' b1 high level in a standard cell bank. The low level output unit 12 may employ a logic cell TIELO for outputting 1' b0 low level in a standard cell library.

In one embodiment, the high output unit 11 and the low output unit 12 can be formed on the first metal layer. The metal interconnection line 13 may be formed at the second metal layer.

It should be noted that the first Metal layer in the embodiment of the present invention may be Metal 1. The second Metal layer may be Metal 2. The first Metal layer may be Metal2 and the second Metal layer may be Metal 3. In the embodiment of the present invention, the "first" in the first metal layer and the "second" in the second metal layer are only used to distinguish that the first metal layer and the second metal layer are not the same metal layer, that is, the metal layers where the high-level output unit 11 and the low-level output unit 12 are located and the metal layers formed by the metal interconnection lines 13 are different metal layers.

In an embodiment of the invention, the first metal layer and the second metal layer may be adjacent.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
