摘要:
An interlayer dielectric for preventing Cu ion migration in semiconductor structure containing a Cu region is provided. The interlayer dielectric of the present invention comprises a dielectric material that has a dielectric constant of 3.0 or less and an additive which is highly-capable of binding Cu ions, yet is soluble in the dielectric material. The presence of the additive in the low k dielectric allows for the elimination of conventional inorganic barrier materials such as SiO2 or Si3N4.

摘要:
A solid state chain extension method provides for the formation of a solid state film comprised of a high molecular weight polymer by chain extending a deblocked Lewis base with Lewis acid oligomers while the reactants are in a solid state form. In one embodiment, a negative resist is prepared by selectively exposing regions of the solid state film. The Lewis base is deblocked at the exposed regions by a suitable deblocking means. The Lewis acid oligomers and the deblocked Lewis base chain extend at the exposed regions. Development of the film removes the non-polymerized reactants. Optionally, the Lewis acid oligomers, when radiation-cross-linking, are cross-linked with one another prior to deblocking the Lewis base to form a negative resist. The cross-linked oligomers polymerize with the subsequently deblocked base to provide a high molecular weight polymer film. In an alternative embodiment, a positive resist is used by degrading and removing photo-sensitive Lewis acid oligomers using selective exposure lithography techniques and, subsequently, deblocking the Lewis base and chain extending the remaining oligomers with the deblocked Lewis base at the unexposed regions.
摘要:
The present invention includes a multilevel air-gap-containing interconnect wiring structure including: a collection of interspersed line levels and via levels, the via levels and line levels containing conductive via and line features embedded in a dielectric having an air-gap and solid dielectric. The air-gap and solid dielectric includes (i) one or more solid dielectrics only in the shadows of the conductive features in overlying levels and (ii) a gaseous dielectric elsewhere in the structure. The collection of line levels and via levels are topped by a laminated thin, taut insulating cover layer having openings to selected conductive features in the topmost underlying line or via layer, and the openings are filled with conductive material connecting to terminal pad contacts on the insulating cover layer.

A method to achieve a very low effective dielectric constant in high performance back end of the line chip interconnect wiring and the resulting multilayer structure are disclosed. The process involves fabricating the multilayer interconnect wiring structure by methods and materials currently known in the state of the art of semiconductor processing; removing the intralevel dielectric between the adjacent metal features by a suitable etching process; applying a thin passivation coating over the exposed etched structure; annealing the etched structure to remove plasma damage; laminating an insulating cover layer to the top surface of the passivated metal features; optionally depositing an insulating environmental barrier layer on top of the cover layer; etching vias in the environmental barrier layer, cover layer and the thin passivation layer for terminal pad contacts; and completing the device by fabricating terminal input/output pads. The method obviates issues such as processability and thermal stability associated with low dielectric constant materials by avoiding their use. Since air, which has the lowest dielectric constant, is used as the intralevel dielectric the structure created by this method would possess a very low capacitance and hence fast propagation speeds. Such structure is ideally suitable for high density interconnects required in high performance microelectronic device chips.

A control system for a blind microwave radiation tool a workpiece is described. The controlled system automatically tunes the cavity containing the workpiece. The control system automatically controls the temperature of the workpiece according to a predetermined temperature versus time schedule. Control system automatically determines when the workpiece has reached a particular predetermined physical condition. To achieve these results the control system automatically monitors applied power, reflected power or current temperature and automatically controls the microwave antennae location and the cavity short location in order to maintain the cavity in resonance and to determine when to exit without operator intervention. Control system can run on a small computer and is useful for automatically curing polyamic acid to polyimide to a predetermined percent cure automatically without operator intervention.
