摘要： The present invention relates to a bilayer cap structure for interconnect structures that comprise copper metallization or other conductive metallization. Such bilayer cap structure includes a first cap layer formed by an unbiased high density plasma (HDP) chemical vapor deposition process, and a second cap layer over the first cap layer, where the second cap layer is formed by a biased high density plasma (bHDP) chemical vapor deposition process. During the bHDP chemical vapor deposition process, a low AC bias power is applied to the substrate to increase the ion bombardment on the substrate surface and to induce resputtering of the capping material, thereby forming a seamless second cap layer with excellent reactive ion etching (RIE) selectivity.

摘要： An interconnect structure and method of making the same are provided. The interconnect structure includes a dielectric layer having a patterned opening, a metal feature disposed in the patterned opening, and a dielectric cap overlying the metal feature. The dielectric cap has an internal tensile stress, the stress helping to avoid electromigration from occurring in a direction away from the metal line, especially when the metal line has tensile stress.

摘要： A method of fabricating a gate structure in a metal oxide semiconductor field effect transistor (MOSFET) and the structure thereof is provided. The MOSFET may be n-doped or p-doped. The gate structure, disposed on a substrate, includes a plurality of gates. Each of the plurality of gates is separated by a vertical space from an adjacent gate. The method deposits at least one dual-layer liner over the gate structure filling each vertical space. The dual-layer liner includes at least two thin high density plasma (HDP) films. The deposition of both HDP films occurs in a single HDP chemical vapor deposition (CVD) process. The dual-layer liner has properties conducive for coupling with plasma enhanced chemical vapor deposition (PECVD) films to form tri-layer or quadric-layer film stacks in the gate structure.
