摘要:
A semiconductor interconnect structure including a semiconductor substrate, a semiconductor active device formed in the substrate, a layer of low-k dielectric material, a first patterned conducting layer, a second patterned conducting layer, and a cap layer formed thereon. The low-k material layer is formed over the semiconductor device. The first conducting line is formed in the low-k material layer and connected to the semiconductor active device. The second conducting line is formed in the low-k material layer but not electrically connected to the semiconductor active device. The cap layer is formed over the low-k material layer, the first and second conducting lines. The cap layer includes silicon and carbon. Since the adhesion strength between the cap layer and the patterned conducting layer is greater than the adhesion strength between the cap layer and the low-k material layer, the addition of second patterned conducting layer would eliminate the overall possibility of delamination between the surface where cap layer is in contact with the low-k material and the first and the second patterned conducting layers.

A method of manufacturing a MOS transistor device is provided. First, a semiconductor substrate having a gate structure is prepared. The gate structure has two sidewalls and a liner on the sidewalls. Subsequently, a stressed cap layer is formed on the semiconductor substrate, and covers the gate structure and the liner. Next, an activating process is performed. Furthermore, the stressed cap layer is etched to be a salicide block. Afterward, a salicide process is performed to form a silicide layer on the regions that are not covered by the stressed cap layer.

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.
