    摘要: An annealing method and apparatus for semiconductor manufacturing is described. The method and apparatus allows an anneal that can span a thermal budget and be tailored to a specific process and its corresponding activation energy. In some cases, the annealing method spans a timeframe from about 1 millisecond to about 1 second. An example for this annealing method includes a sub-second anneal method where a reduction in the formation of nickel pipes is achieved during salicide processing. In some cases, the method and apparatus combine the rapid heating rate of a sub-second anneal with a thermally conductive substrate to provide quick cooling for a silicon wafer. Thus, the thermal budget of the sub-second anneal methods may span the range from conventional RTP anneals to flash annealing processes (including duration of the anneal, as well as peak temperature). Other embodiments are described.

    摘要: Embodiments relate to a substrate or wafer edge support having an emmisivity greater than that of a silicon wafer, where the edge support is for supporting a wafer during processing to form circuit devices on or in the wafer. Embodiments also include temperature sensors, heat conducting gas jets, and photonic energy can be directed to sense and control the temperature of the edge support and/or wafer edge during annealing to reduce temperature roll-off or roll-up at the edge as compared to the center of the wafer. Specifically, use of an edge support having an emmisivity greater than or equal to that of the wafer during processing allows helium gas jets directed at the edge support and/or wafer edge to reduce temperature roll-up at the edge during annealing. Because wafers from different processes and anneal locations may all have different emmisivities, use of the feedback loop will enable one edge ring to support the uniform anneal of wafers with a range of different emmisivities.
