摘要： A method is described for forming a low-k dielectric film, in particular, a pre-metal dielectric (PMD) on a semiconductor wafer which has good gap-filling characteristics. The method uses a thermal sub-atmospheric CVD process that includes a carbon-containing organometallic precusor such as TMCTS or OMCTS, an ozone-containing gas, and a source of dopants for gettering alkali elements and for lowering the reflow temperature of the dielectric while attaining the desired low-k and gap-filling properties of the dielectric film. Phosphorous is a preferred dopant for gettering alkali elements such as sodium. Additional dopants for lowering the reflow temperature include, but are not limited to boron, germanium, arsenic, fluorine or combinations thereof.

摘要： A structure and method for an insulator layer having carbon-graded layers above a substrate is disclosed, wherein the concentration of carbon increases in each successive carbon-graded layer above the substrate. The insulator comprises a low-k dielectric having a dielectric constant less than 3.3. The carbon-graded layer increases adhesion between the substrate and the insulator and between the insulator and the conductor layer. The structure may also include stabilization interfaces between the carbon-graded layers. More specifically, the carbon-graded layers include a first layer adjacent the substrate having a carbon content between about 5% and 20%, a second layer above the first layer having a carbon content between about 10% and 30%, and a third layer above the second layer having a carbon content between about 20% and 40%.

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： The present invention relates to a bilayer cap structure for interconnect structures that comprise copper metallization or other conductive metallization. Such bilayer cap structure includes a first cap layer formed by an unbiased high density plasma (HDP) chemical vapor deposition process, and a second cap layer over the first cap layer, where the second cap layer is formed by a biased high density plasma (bHDP) chemical vapor deposition process. During the bHDP chemical vapor deposition process, a low AC bias power is applied to the substrate to increase the ion bombardment on the substrate surface and to induce resputtering of the capping material, thereby forming a seamless second cap layer with excellent reactive ion etching (RIE) selectivity.
