    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 semiconductor structure comprises: a first inter-layer dielectric (ILD) over a substrate; a first metal layer; a plurality of second ILDs over the first ILD; and a plurality of second metal layers, each of the second metal layers is over one of the second ILDs. The first ILD is not cured. It has a k value of between about 2.5 and about 3.0, a pore size of smaller than about 10 Å, and a hardness of greater than about 1.5 Gpa. The second ILDs are cured therefore having lower k values of smaller than about 2.5, pore sizes of greater than about 10 Å, and hardness of smaller than about 1.5 Gpa. The semiconductor structure has reduced plasma charge damage from plasma curing.
