The semiconductor circuit according to claim 1 , wherein the transistors of the matching structure are arranged adjacent to one another, and wherein within one and the same metallization level at least one trace of the geometry above a transistor adjoins at least one trace of a neighboring transistor to form a conducting connection.
3. The semiconductor circuit according to claim 1 , wherein, at least within the lowest via level, a position of the vias is substantially the same relative to a structure of each transistor.
4. The semiconductor circuit according to claim 3 , wherein in a third via level or in a via level above the third via level, a position of the vias relative to the structure of each transistor for connection of the transistors to one another is different.
5. The semiconductor circuit according to claim 1 , wherein the geometry of the traces within at least one metallization level has a plurality of strips parallel to one another, particularly at an equidistant spacing.
6. The semiconductor circuit according to claim 1 , wherein the matching structure has dummy transistors, which have a structure that resembles that of the transistors, wherein the dummy transistors are arranged at an edge of the matching structure, and wherein within one and the same metallization level, the geometry of the traces above each transistor and each dummy transistor is formed substantially the same.
7. The semiconductor circuit according to claim 1 , wherein automatically arranged filling structures are provided only outside the matching structure between traces of the metallization levels.
