Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 160 words
An integrated circuit package comprising: a multilayer wiring portion having a first surface on which at least one integrated circuit is mounted and a second surface opposite the first surface, the multilayer wiring portion having a plurality of laminated wiring layers, said plurality of wiring layers including insulating films having a low dielectric constant and conductor films; an insulating substrate formed of insulating material for mounting the second surface of said multilayer wiring portion thereto, said insulating substrate being provided with substrate wiring electrically connected through said multilayer wiring portion to the at least one integrated circuit; and an electrical connection for electrically connecting said at least one integrated circuit with the substrate wiring of said insulating substrate, the electrical connection including a grouping of a plurality of coextensive conductor columns extending through the multilayer wiring portion, said conductor columns of the grouping being electrically connected in parallel by the multilayer wiring portion to improve reliability of the electrical connection.
Claim 2
Dependent Claim 160 words
An integrated circuit package comprising: a multilayer wiring portion having a first surface on which at least one integrated circuit is mounted and a second surface opposite the first surface, the multilayer wiring portion having a plurality of laminated wiring layers, said plurality of wiring layers including insulating films having a low dielectric constant and conductor films; an insulating substrate formed of insulating material for mounting the second surface of said multilayer wiring portion thereto, said insulating substrate being provided with substrate wiring electrically connected through said multilayer wiring portion to the at least one integrated circuit; and an electrical connection for electrically connecting said at least one integrated circuit with the substrate wiring of said insulating substrate, the electrical connection including a grouping of a plurality of coextensive conductor columns extending through the multilayer wiring portion, said conductor columns of the grouping being electrically connected in parallel by the multilayer wiring portion to improve reliability of the electrical connection.
Claim 3
Dependent Claim 26 words
The integrated circuit package of claim 1, wherein the grouping of conductor columns of the electrical connection is used for signal path for an I/O port.
Claim 4
Dependent Claim 38 words
The integrated circuit package of claim 1 further comprising a second electrical connection having at least one conductor column extending through the multilayer wiring portion electrically independent of the grouping of conductor columns of the first electrical connection.
