    摘要: A through silicon via structure is provided, including a substrate, an isolation layer, a conductive layer and a dielectric layer. The substrate has a through-hole therein. The isolation layer is disposed on two sidewalls of the through-hole. The conductive layer is disposed in the through-hole and covers the isolation layer, and the conductive layer includes a first portion and a second portion, wherein the first portion fills a portion of the through-hole, and the second portion is located on the sidewalls in the other portion of the through-hole, such that the conductive layer has a concave part. The dielectric layer is disposed in the concave part and fills the concave part.

    摘要: A method of forming the multi metal layers thin film has Ti sputtered on top surface of a substrate by PVD first. Then, Ti is transformed into TiN via CVD. Thus, by skipping the extra process steps of wafer cleaning and surface treating, the method not only solves the stress problems between two different metal layers but also improves the cycle time and particle performance for the production without any yield impact.
