    摘要: A method of fabricating a gate structure in a metal oxide semiconductor field effect transistor (MOSFET) and the structure thereof is provided. The MOSFET may be n-doped or p-doped. The gate structure, disposed on a substrate, includes a plurality of gates. Each of the plurality of gates is separated by a vertical space from an adjacent gate. The method deposits at least one dual-layer liner over the gate structure filling each vertical space. The dual-layer liner includes at least two thin high density plasma (HDP) films. The deposition of both HDP films occurs in a single HDP chemical vapor deposition (CVD) process. The dual-layer liner has properties conducive for coupling with plasma enhanced chemical vapor deposition (PECVD) films to form tri-layer or quadric-layer film stacks in the gate structure.

    摘要: A method is provided for making a FET device in which a nitride layer overlies the PFET gate structure, where the nitride layer has a compressive stress with a magnitude greater than about 2.8 GPa. This compressive stress permits improved device performance in the PFET. The nitride layer is deposited using a high-density plasma (HDP) process, wherein the substrate is disposed on an electrode to which a bias power in the range of about 50 W to about 500 W is supplied. The bias power is characterized as high-frequency power (supplied by an RF generator at 13.56 MHz). The FET device may also include NFET gate structures. A blocking layer is deposited over the NFET gate structures so that the nitride layer overlies the blocking layer; after the blocking layer is removed, the nitride layer is not in contact with the NFET gate structures. The nitride layer has a thickness in the range of about 300-2000 Å.

    摘要: Methods of forming a mask for implanting a substrate and implanting using an implant stopping layer with a photoresist provide lower aspect ratio masks that cause minimal damage to trench isolations in the substrate during removal of the mask. In one embodiment, a method of forming a mask includes: depositing an implant stopping layer over the substrate; depositing a photoresist over the implant stopping layer, the implant stopping layer having a density greater than the photoresist; forming a pattern in the photoresist by removing a portion of the photoresist to expose the implant stopping layer; and transferring the pattern into the implant stopping layer by etching to form the mask. The implant stopping layer may include: hydrogenated germanium carbide, nitrogenated germanium carbide, fluorinated germanium carbide, and/or amorphous germanium carbon hydride (GeHX), where X includes carbon. The methods/mask reduce scattering during implanting because the mask has higher density than conventional masks.

    摘要: A method is provided for filling high aspect ratio gaps without void formation by using a high density plasma (HDP) deposition process with a sequence of deposition and etch steps having varying etch rate-to-deposition rate (etch/dep) ratios. The first step uses an etch/dep ratio less than one to quickly fill the gap. The first step is interrupted before the opening to the gap is closed. The second step uses an etch/dep ratio greater than one to widen the gap. The second step is stopped before corners of the elements forming the gaps are exposed. These steps can be repeated until the aspect ratio of the gap is reduced so that void-free gap-fill is possible. The etch/dep ratio and duration of each step can be optimized for high throughput and high aspect ratio gap-fill capacity.
