    摘要: The method and apparatus disclosed herein relate to preparing a stack structure for an electronic device on a semiconductor substrate. A particularly beneficial application of the method is in reduction of internal stress in a stack containing multiple layers of silicon. Typically, though not necessarily, the internal stress is a compressive stress, which often manifests as wafer bow. In some embodiments, the method reduces the internal stress of a work piece by depositing phosphorus doped silicon layers having low internal compressive stress or even tensile stress. The method and apparatus disclosed herein can be used to reduce compressive bow in stacks containing silicon.

    摘要: The methods and apparatus disclosed herein concern a process that may be referred to as a “soft anneal.” A soft anneal provides various benefits. Fundamentally, it reduces the internal stress in one or more silicon layers of a work piece. Typically, though not necessarily, the internal stress is a compressive stress. A particularly beneficial application of a soft anneal is in reduction of internal stress in a stack containing two or more layers of silicon. Often, the internal stress of a layer or group of layers in a stack is manifest as wafer bow. The soft anneal process can be used to reduce compressive bow in stacks containing silicon. The soft anneal process may be performed without causing the silicon in the stack to become activated.
