    摘要: A method for planarizing a semiconductor structure is disclosed. A semiconductor substrate having a first area in which one or more trenches are formed in a first pattern density, and a second area in which one or more trenches are formed in a second pattern density lower than the first pattern density, is provided. A first dielectric layer is formed above the semiconductor for covering the trenches in the first and second areas. A first chemical mechanical polishing is performed on the first dielectric layer using a predetermined type of slurry for reducing a thickness thereof. The first dielectric layer is then rinsed. A second chemical mechanical polishing is performed on the first dielectric layer using the predetermined type of slurry for further removing the first dielectric layer outside the trenches, thereby reducing a step height variation between surfaces of the first and second areas.

    摘要: A method of manufacturing a semiconductor device having a porous, low-k dielectric layer is provided. A preferred embodiment comprises the steps of forming a porogen-containing, low-k dielectric layer, in the damascene process. In preferred embodiments, pore generation, by e-beam porogen degradation, occurs after the steps of CMP planarizing the damascene copper conductor and depositing a semipermeable cap layer. In alternative embodiments, the cap layer consists essentially of silicon carbide, silicon nitride, Co, W, Al, Ta, Ti, Ni, Ru, and combinations thereof. The semipermeable cap layer is preferably deposited under PECVD conditions such that the cap layer is sufficiently permeable to enable removal of porogen degradation by-products. Preferred embodiments further include an in-situ N2/NH3 treatment before depositing the semipermeable cap layer.
