    摘要: A novel test device and method for calibrating the alignment of a laser beam emitted from a laser metrology tool with respect to a target area on a substrate. The test device includes a laser-sensitive material having a calibration pattern that includes a target point. When the tool is properly adjusted, the laser beam strikes the target point and is released to production. If the laser beam misses the target point, the tool is re-adjusted and re-tested until the laser beam strikes the target point.

    摘要: A method is disclosed for depositing a Black Diamond layer in a CVD chamber. Trimethylsilane, O2, and Ar are flowed into the chamber at 300° C. to 400° C. with an O2:Ar:trimethylsilane flow rate ratio that is preferably 1:1.5:6. The resulting low k dielectric layer is formed with a higher deposition rate than when Ar is omitted and has a k value of about 3 that increases only slightly in O2 plasma. A higher density, hardness, and tensile strength are achieved in the Black Diamond layer when Ar is included in the deposition process. The addition of Ar in the deposition maintains film thickness uniformity below 2% for a longer period so that PM cleaning operations are less frequent and affords a lower fluorocarbon plasma etch rate to enable improved trench depth control in a damascene scheme. A lower leakage current and higher breakdown voltage in achieved in the resulting metal interconnect.

    摘要: A method of forming a PE-silane oxide layer with a greatly reduced particle count is described. A semiconductor substrate is provided over which a silicon oxide film is to be formed. The silicon oxide film is formed by the steps of: 1) pre-flowing a non-silane gas into a deposition chamber for at least two seconds whereby the pre-flowing step prevents formation of particles on the silicon oxide film, and 2) thereafter depositing a silicon oxide film by chemical vapor deposition by flowing a silane gas into the deposition chamber to complete formation of a silicon oxide film using plasma-enhanced chemical vapor deposition in the fabrication of an integrated circuit.

    摘要: A method for forming a patterned reflective layer first employs a substrate. There is then formed over the substrate a blanket reflective layer. There is then formed upon the blanket reflective layer an anti-reflective coating (ARC) layer formed employing a plasma enhanced chemical vapor deposition (PECVD) method employing a deposition gas composition comprising silane, nitrous oxide and argon. There is then formed upon the blanket anti-reflective coating (ARC) layer a blanket photoresist layer. There is then photoexposed and developed the blanket photoresist layer to form a patterned photoresist layer. There is then etched, while employing a first etch method, the blanket anti-reflective coating (ARC) layer to form a patterned anti-reflective coating (ARC) layer while employing the patterned photoresist layer as a first etch mask layer. Finally, there is then etched, while employing a second etch method, the blanket reflective layer to form the patterned reflective layer while employing at least the patterned anti-reflective coating (ARC) layer as a second etch mask layer.

    摘要: A simple method for calculating the optimum amount of HDP deposited material that needs to be removed during CMP (without introducing dishing) is described. This method derives from our observation of a linear relationship between the amount of material that needs to be removed in order to achieve full planarization and a quantity called “OD for CMP density”. The latter is defined as PA×(100−PS) where PA is the percentage of active area relative to the total wafer area and PS is the percentage of sub-areas relative to the total wafer area. The sub-areas are regions in the dielectric, above the active areas, that are etched out prior to CMP. Thus, once the materials have been characterized, the optimum CMP removal thickness is readily calculated for a wide range of different circuit implementations.
