摘要:
A method of fabricating a shallow trench isolation structure is disclosed. On a substrate, a pad oxide layer and a mask layer are successively formed. The pad oxide layer, the mask layer and a portion of the substrate are patterned to form a trench. After performing a rapid wet thermal process, a liner layer is formed on the exposed surface of the substrate, including the exposed silicon surface of the substrate in the trench and sidewalls and the surface of the mask layer. An oxide layer is deposited over the trench and the substrate and fills the trench. A planarization process is performed until the mask layer is exposed. The mask layer and the pad oxide layer are removed to complete the shallow trench isolation structure.

摘要:
A manufacturing method of shallow trench isolation (STI) structure is described. A substrate is provided, wherein a patterned pad oxide layer and a mask layer are formed on the substrate, and at least a trench is formed in the substrate, wherein the trench is formed by exposing a portion of the pad oxide layer and the mask layer. Then, a liner layer on a surface of the trench is formed. A high density plasma chemical vapor deposition (HDP-CVD) process is performed to form an isolation layer on the substrate and over the trench, wherein the trench is at least filled with the isolation layer. The HDP-CVD process includes a first stage process and a second stage process. The bias power of the second stage process is larger than the bias power of the first stage process. Thereafter, the isolation layer over the trench, the mask layer and the pad oxide layer are removed sequentially.

摘要:
A method of coating an organic polymeric low-k dielectric layer starts by depositing a protective layer composed of silicon nitride (SiN) or silicon carbide (SiC) on a substrate. A hydrophilic surface is produced across a top surface of the protective layer by performing a fast surface treatment that subjects the surface to an oxygen-containing plasma at a pre-selected low radio frequency power. An adhesion promoter coating layer is formed over the top surface of the protective layer. The coating layer has promoter molecules, each promoter molecule having at least one hydrophobic group and one hydrophilic group. The low-k dielectric layer is spin-on coated onto the coating layer. Formation of the hydrophilic surface alters an orientation of the adhesion promoter molecules to facilitate the hydrophilic group of each of the adhesion promoter molecules facing the hydrophilic surface while the hydrophobic group of the adhesion promoter molecules faces the low-k dielectric layer.
