摘要:
A method for manufacturing a circuit includes the step of providing a first wiring level comprising first wiring level conductors separated by a first wiring level dielectric material. A first dielectric layer with a plurality of interconnect openings and a plurality of gap openings is formed above the first wiring level. The interconnect openings and the gap openings are pinched off with a pinching dielectric material to form relatively low dielectric constant (low-k) volumes in the gap openings. Metallic conductors comprising second wiring level conductors and interconnects to the first wiring level conductors are formed at the interconnect openings while maintaining the relatively low-k volumes in the gap openings. The gap openings with the relatively low-k volumes reduce parasitic capacitance between adjacent conductor structures formed by the conductors and interconnects.
摘要:
The circuit structure includes at least two generally parallel conductor structures, and a plurality of substantially horizontal layers of layer dielectric material interspersed with substantially horizontally extending relatively low dielectric constant (low-k) volumes. The substantially horizontal layers and the substantially horizontally extending volumes are generally interposed between the at least two generally parallel conductor structures. Also included are a plurality of substantially vertically extending relatively low-k volumes sealed within the substantially horizontal layers and the substantially horizontally extending volumes between the at least two generally parallel conductor structures. The substantially vertically extending relatively low-k volumes and the substantially horizontally extending relatively low-k volumes reduce parasitic capacitance between the at least two generally parallel conductor structures as compared to an otherwise comparable microelectronic circuit not including the relatively low-k volumes.

A method for manufacturing a microelectronic circuit includes the steps of providing a first wiring level comprising first wiring level conductors separated by a first wiring level dielectric material; forming a plurality of alternating layers of layer dielectric material and sacrificial material over the first wiring level; and forming a plurality of interconnect openings and a plurality of gap openings in the alternating layers of layer dielectric material and sacrificial material. The interconnect openings are formed over the first wiring level conductors. The method further includes forming (i) metallic conductors comprising second wiring level conductors, and (ii) interconnects, at the interconnect openings; and removing the layers of the sacrificial material through the gap openings.
摘要:
An integrated circuit design and a method of fabrication and, more particularly, a semiconductor structure having an ultra narrow crack stop for use in multilevel level devices and a method of making the same. The structure includes a first dielectric layer having a first connection connecting to an underlying interconnect and a second dielectric layer having a second connection connecting to the first connection. A stop gap structure extends through the first dielectric layer and the second dielectric layer, and has a width of about less than 1 um.

Electrical fuses and resistors having a sublithographic lateral or vertical dimension are provided. A conductive structure comprising a conductor or a semiconductor is formed on a semiconductor substrate. At least one insulator layer is formed on the conductive structure. A recessed area is formed in the at least one insulator layer. Self-assembling block copolymers are applied into the recessed area and annealed to form a fist set of polymer blocks and a second set of polymer blocks. The first set of polymer blocks are etched selective to the second set and the at least one insulator layer. Features having sublithographic dimensions are formed in the at least one insulator layer and/or the conductive structure. Various semiconductor structures having sublithographic dimensions are formed including electrical fuses and resistors.
