  • Publication number: 20130330847
    Abstract: The present disclosure provides a method and system for characterizing a pattern loading effect. A method may include performing a reflectivity measurement on a semiconductor wafer and determining an anneal process technique based on the reflectivity measurement. The determining the anneal process technique may include determining a spatial distance for a reflectivity change using a reflectivity map generated using the reflectivity measurement. This spatial distance is compared with the thermal diffusion length associated with each of the plurality of anneal process techniques. In an embodiment, a thermal profile map and/or a device performance map may be provided.

  • Publication number: 20120015459
    Abstract: A semiconductor device and a method of manufacturing are provided. In some embodiments, a backside annealing process such that a first heat source is placed along a backside of the substrate. In other embodiments, the first heat source is used in combination with an anti-reflection dielectric (ARD) layer is deposited over the substrate. In yet other embodiments, a second heat source is placed along a front side of the substrate in addition to the first heat source placed on the backside of the substrate. In yet other embodiments, a heat shield may be placed between the substrate and the second heat source on the front side of the substrate. In yet further embodiments, a single heat source may be used on the front side of the substrate in combination with the ARD layer. A reflectivity scan may be performed to determine which anneal stage (RTA or MSA or both) to place thermal leveling solution.

  • Publication number: 20110295539
    Abstract: A method for measuring the intra-die temperature of a wafer with a fast response time is described. The method includes providing a wafer in a thermal process chamber, radiating the wafer in a first predetermined radiation range to heat the wafer to a predetermined temperature range for a predetermined time, receiving the radiation reflected from a die area while the wafer is being heated and detecting reflected radiation having a second predetermined radiation range, and determining a temperature of the die area by a processor being responsive to the detected second predetermined radiation range.
