Abstract
An integrated circuit (IC) including an IC cell arranged in a row of IC cells, wherein the IC cells in the row have substantially the same height, wherein the IC cell includes a portion of an intercell metal interconnect terminating at the IC cell at a metal layer or extending entirely through the IC cell on the metal layer and electrically connecting together a pair of nodes of a pair of IC cells, respectively.
Claims25
An integrated circuit, comprising:
- a first IC cell arranged in a first row of IC cells including a first pair of IC cells between which the first IC cell is situated, wherein the IC cells in the first row have substantially the same height, wherein the first IC cell comprises a first portion of a first intercell metal interconnect extending through the first IC cell entirely on the first metal layer and electrically connecting together a first pair of nodes of the first pair of IC cells in the first row, respectively.
An integrated circuit, comprising:
- a first IC cell arranged in a first row with and between a first pair of IC cells, wherein the first IC cell and the first pair of IC cells have a first height, wherein the first IC cell comprises a first portion of a first intercell metal interconnect extending along a first routing channel entirely on a first metal layer and electrically connecting together a first pair of nodes of the first pair of IC cells, respectively;
- and
- a second IC cell arranged in a second row with and between a second pair of IC cells, wherein the second IC cell and the second pair of IC cells have a second height, wherein the second IC cell comprises a second portion of a second intercell metal interconnect extending along a second routing channel entirely on the first metal layer or a second metal layer and electrically connecting together a second pair of nodes of the second pair of IC cells, respectively.
An integrated circuit, comprising:
- a set of rows of IC cells, wherein at least one IC cell in at least one row comprises a portion of an intercell metal interconnect extending along a routing channel entirely on a metal layer M1 or M2 and electrically connecting together a pair of nodes of a pair of IC cells between which the at least one IC cell is situated in the same row, respectively.
A first integrated circuit (IC) cell, comprising:
- a routing channel including an intercell metal interconnect on a metal layer M1 or a metal layer M2 for routing an input signal or an output signal between second and third IC cells through a first IC cell located between the second and third IC cells, wherein the first, second and third IC cells are at least partially in a same row.
