Patent number: 9659769Abstract: A highly tensile dielectric layer is generated on a heat sensitive substrate while not exceeding thermal budget constraints. Ultraviolet (UV) irradiation is used to produce highly tensile films to be used, for example, in strained NMOS transistor architectures. UV curing of as-deposited PECVD silicon nitride films, for example, has been shown to produce films with stresses of at least 1.65 E10 dynes/cm2. Other dielectric capping layer film materials show similar results. In transistor implementations, the stress from a source/drain region capping layer composed of such a film is uniaxially transferred to the NMOS channel through the source-drain regions to create tensile strain in the NMOS channel.Type: GrantFiled: October 22, 2004Date of Patent: May 23, 2017Assignee: Novellus Systems, Inc.Inventors: Bhadri Varadarajan, Sean Chang, James S.

Patent number: 8715788Abstract: Methods and apparatus for improving mechanical properties of a dielectric film on a substrate are provided. In some embodiments, the dielectric film is a carbon-doped oxide (CDO). The methods involve the use of modulated ultraviolet radiation to increase the mechanical strength while limiting shrinkage and limiting any increases in the dielectric constant of the film. Methods improve film hardness, modulus and cohesive strength, which provide better integration capability and improved performance in the subsequent device fabrication procedures such as chemical mechanical polishing (CMP) and packaging.Type: GrantFiled: October 17, 2011Date of Patent: May 6, 2014Assignee: Novellus Systems, Inc.Inventors: Ananda K.

Patent number: 7799705Abstract: Methods of preparing a low stress porous low-k dielectric material on a substrate are provided. The methods involve the use of a structure former precursor and/or porogen precursor with one or more organic functional groups. In some cases, the structure former precursor has carbon-carbon double or triple bonds. In other cases, one or both of the structure former precursor and porogen precursor has one or more bulky organic groups. In other cases, the structure former precursor has carbon-carbon double or triple bonds and one or both of the structure former precursor and porogen precursor has one or more bulky organic groups. Once the precursor film is formed, the porogen is removed, leaving a porous low-k dielectric matrix with high mechanical strength.

Patent number: 6214526Abstract: An antireflective layer for use in semiconductor photolithography is fabricated of silicon nitride (Si1−x−yNxHy) in a plasma-enhanced chemical vapor deposition process using a gaseous mixture of ammonia, silane and nitrogen. By varying the process temperature and the ratio of ammonia to silane, acceptable values of the refractive index n and extinction coefficient k can be obtained. The silicon nitride layer produced by this technique etches rapidly and therefore allows the antireflective layer to be removed quickly, thereby minimizing the damage to the underlying structures in a semiconductor device.Type: GrantFiled: February 17, 1998Date of Patent: April 10, 2001Assignee: Novellus Systems, Inc.Inventors: Srinivasan Sundararajan, Kenneth P.

Patent number: 5114242Abstract: The system and method for pyrometrically determining the temperature of a semiconductor wafer within a processing chamber accurately determines the actual emissivity of the semiconductor wafer at a reference temperature using multiple pyrometers operating at different wavelengths. The pyrometers are calibrated for radiation received from the processing chamber and their responses are then corrected to provide the proper temperature indication for a master wafer at a known reference temperature to yield emissivity of the master wafer. Other similar wafers exhibiting extreme values of emissivity are sensed at the reference temperature to provide pyrometer responses that are corrected in accordance with the master emissivity, and such corrected responses are used to establish a correlation between emissivities and the corrected pyrometer responses.Type: GrantFiled: December 7, 1990Date of Patent: May 19, 1992Assignee: AG Processing Technologies, Inc.Inventors: Arnon Gat, David Mordo
