    摘要: A method for forming a semiconductor structure includes forming a gate stack over a semiconductor substrate in a wafer; forming a recess in the semiconductor substrate and adjacent the gate stack; and performing a selective epitaxial growth to grow a semiconductor material in the recess to form an epitaxy region. The step of performing the selective epitaxial growth includes performing a first growth stage with a first growth-to-etching (E/G) ratio of process gases used in the first growth stage; and performing a second growth stage with a second E/G ratio of process gases used in the second growth stage different from the first E/G ratio.

    摘要: An apparatus, a system and a method are disclosed. An exemplary apparatus includes a wafer holder including a first portion and a second portion. The first and second portions are formed of the same continuous material. The first portion includes a first upper surface and a first lower surface, and the second portion including a second upper surface and a second lower surface. The apparatus further includes an interface between the first and second portions. The interface provides for a transition such that the first upper surface of the first portion tends toward the second upper surface of the second portion. The apparatus further includes a tapered region formed in the first portion. The tapered region starts at a radial distance from a center line of the wafer holder and terminates at the interface. The tapered region has an initial thickness that gradually decreases to a final thickness.
