Structure and method of repair of integrated circuits

A method of manufacturing an integrated circuit, at least a portion of the integrated circuit including a plurality of groups of standby cells connectable to the portion of the integrated circuit by replacement connections having a predetermined length, the method comprising steps of:

• providing a plurality of metal standby tracks being disposed on the integrated circuit such that any node of the portion is distant by at most the predetermined length from any point on the metal standby tracks;
• connecting inputs and outputs of the standby cells to the plurality of metal standby tracks;
• connecting inputs of a first group of the plurality of groups of standby cells to a ground of the integrated circuit;
• and
• connecting other groups of the plurality of groups of standby cells in series with the first group of standby cells using standby tracks arranged side by side in groups of standby tracks, so that no input of a standby cell is floating.

A method of manufacturing an integrated circuit comprising steps of:

• implanting at least one group of standby cells into a portion of the integrated circuit, the group of standby cells being connectable, after manufacturing of the integrated circuit, to nodes of the portion of the integrated circuit by replacement connections that do not exceed a predetermined length;
• providing a plurality of non-overlapping metal standby tracks on the integrated circuit, the plurality of metal standby tracks being arranged such that any one of the nodes of the portion of the integrated circuit is distant from any point on the plurality of metal standby tracks by at most the predetermined length;
• and
• connecting inputs and outputs of the group of standby cells to the plurality of metal standby tracks.

A method of manufacturing an integrated circuit, at least one portion of the integrated circuit including a group of standby cells connectable to the portion of the integrated circuit by replacement connections having a predetermined length, the method comprising steps of:

• connecting inputs and outputs of the standby cells to metal standby tracks being disposed on the integrated circuit such that any node of the portion is distant by at most the predetermined length from any point on the metal standby tracks;
• arranging the metal standby tracks into groups of standby tracks in a zigzag pattern on the portion of the integrated circuit in a succession of lines of same direction, extending across an entire width of the portion of the integrated circuit;
• and
• connecting the lines at each end using a portion of perpendicular column substantially equal to twice a length of the replacement connections.
