    摘要: A method for filling silicon nitride materials into a trench includes providing a substrate having a plurality of trenches, performing a first deposition process to form a first silicon nitride layer in the trenches, and performing a second deposition process to form a second silicon nitride layer in the trenches. The reactant gas of the first deposition process has a first O3/TEOS flow ratio larger than a second O3/TEOS flow ratio of the reactant gas of the second deposition process.

    摘要: A method of forming a contact is provided. A substrate having at least two conductive devices is provided. A spacing is located between the two conductive devices. A first dielectric layer is formed over the substrate to cover the two conductive devices and the spacing. A seam is formed in the first dielectric layer within the spacing. Then, a portion of the first dielectric layer is removed to form an opening so that the width of the seam is expanded. A second dielectric layer is formed over the first dielectric layer to fill the opening. A portion of the second dielectric layer and a portion of the first dielectric layer within the spacing are removed until a portion of the surface of the substrate is exposed and a contact opening is formed in the location for forming the contact. Finally, conductive material is deposited to fill the contact opening.

    摘要: A seamless trench fill method utilizing ozone-assisted sub-atmospheric pressure chemical vapor deposition (SACVD) technique is provided. After the deposition of a SACVD silicon oxide film, the substrate is subjected to a steam anneal that is performed under H2/O2 environment at a relatively lower temperature ranging between 500° C. and 800° C. for a time period of no less than 30 minutes. The seam defect in the trench is effectively eliminated by this low-temperature steam anneal. To densify the SACVD silicon oxide film, a subsequent N2 anneal is carried out at a higher temperature, for example, 1050° C.
