Abstract
An electronic device having high density wiring formed in a multi-level layer structure which has a plurality of conductors distributed with high density. Each conductor is formed to have a sectional area which is determined on the basis of length thereof such that ones of the plurality of conductors having relatively longer lengths have sectional areas larger than those ones of relatively shorter lengths. Wirings in the electronic device are formed through effecting electrical connections of conductors having step-wise increasing sectional areas to thereby control the wiring resistance and signal propagation delay thereof and also preclude a malfunction or reduction in operation performance of the device.
Claims20
An electronic device having high-density wiring comprising a plurality of conductors distributed with high density and each being formed to have a sectional area determined on the basis of length thereof.
- wherein ones of said plurality of conductors which have relatively longer lengths have sectional areas which are larger than those ones of said plurality of conductors of relatively shorter lengths, and
- wherein each of said plurality of conductors is formed to have one of a plurality of sectional areas, used for said plurality of conductors in said device, as determined on a basis of the relative length thereof.
An electronic device having high-density wiring comprising a plurality of conductors distributed with high density and each being formed to have a sectional area determined on the basis of length thereof,
- wherein ones of said plurality of conductors which have relatively longer lengths have sectional areas which are larger than those ones of said plurality of conductors of relatively shorter lengths, and
- wherein said plurality of conductors are disposed as plural groups of conductors, each group including one or more conductors having an associated predetermined range of conductor lengths, all conductors of each group are formed to have the same sectional area and the sectional areas of conductors of respectively different conductor groups are different.
An electronic device having high-density wiring comprising a plurality of conductors distributed with high density and each being formed to have a sectional area determined on the basis of length thereof,
- wherein ones of said plurality of conductors which have relatively longer lengths have sectional areas which are larger than those ones of said plurality of conductors of relatively shorter lengths,
- wherein said plurality of conductors are disposed as plural groups of conductors, each group includes conductors having the same sectional area and each group is associated with a predetermined range of conductor lengths, and
- wherein wirings of a predetermined length required in said device are effected through an electrical connection including conductors from one or more of said plural groups of conductors.
