摘要： A structure useful for electrical interconnection comprises a substrate; a plurality of porous dielectric layers disposed on the substrate; an etch stop layer disposed between a first of the dielectric layers and a second of the dielectric layers; and at least one thin, tough, non-porous dielectric layer disposed between at least one of the porous dielectric layers and the etch stop layer. A method for forming the structure comprising forming a multilayer stack of porous dielectric layers on the substrate, the stack including the plurality of porous dielectric layers, and forming a plurality of patterned metal conductors within the multilayer stack. Curing of the multilayer dielectric stack may be in a single cure step in a furnace. The application and hot plate baking of the individual layers of the multi layer dielectric stack may be accomplished in a single spin-coat tool, without being removed, to fully cure the stack until all dielectric layers have been deposited.

摘要： A method for forming a planarized dielectric layer upon a semiconductor wafer is disclosed. In an exemplary embodiment of the invention, the method includes applying an adhesion promoter to the wafer, thereby forming an adhesion promoter layer. A dielectric material is applied in a spin-on fashion upon the adhesion promoter layer at a relative humidity of less than 40% and for a thickness setting duration of less than 30 seconds. Then, the dielectric material is dried by baking without additional spinning of the semiconductor wafer.

摘要： A mechanically robust semiconductor structure with improved adhesion strength between a low-k dielectric layer and a dielectric-containing substrate is provided. In particular, the present invention provides a structure that includes a dielectric-containing substrate having an upper region including a treated surface layer which is chemically and physically different from the substrate; and a low-k dielectric material located on a the treated surface layer of the substrate. The treated surface layer and the low-k dielectric material form an interface that has an adhesion strength that is greater than 60% of the cohesive strength of the weaker material on either side of the interface. The treated surface is formed by treating the surface of the substrate with at least one of actinic radiation, a plasma and e-beam radiation prior to forming of the substrate the low-k dielectric material.

摘要： A reversible fuse structure in an integrated circuit is obtained through the implementation of a fuse cell having a short thin line of phase change materials in contact with via and line structures capable of passing current through the line of phase change material (fuse cell). The current is passed through the fuse cell in order to change the material from a less resistive material to a more resistive material through heating the phase change material in the crystalline state to the melting point then quickly quenching the material into the amorphous state. The reversible programming is achieved by passing a lower current through the fuse cell to convert the high resistivity amorphous material to a lower resistivity crystalline material. Appropriate sense-circuitry is integrated to read the information stored in the fuses, wherein said sense circuitry is used to enable or disable circuitry.
