    摘要: Apparatus and methods for evaporating metal onto semiconductor wafers are disclosed. One such apparatus can include an evaporation chamber that includes a wafer holder, such as a dome, and a test wafer holder that is separate and spaced apart from the wafer holder. In certain implementations, the test wafer can be coupled to a cross beam supporting at least one shaper. A metal can be evaporated onto production wafers positioned in the wafer holder while metal is evaporated on a test wafer positioned in a test wafer holder. In some instances, the production wafers can be GaAs wafers. The test wafer can be used to make a quality assessment about the production wafers.

    摘要: Apparatus and methods for detecting evaporation conditions in an evaporator for evaporating metal onto semiconductor wafers, such as GaAs wafers, are disclosed. One such apparatus can include a crystal monitor sensor configured to detect metal vapor associated with a metal source prior to metal deposition onto a semiconductor wafer. This apparatus can also include a shutter configured to remain in a closed position when the crystal monitor sensor detects an undesired condition, so as to prevent metal deposition onto the semiconductor wafer. In some implementations, the undesired condition can be indicative of a composition of a metal source, a deposition rate of a metal source, impurities of a metal source, position of a metal source, position of an electron beam, and/or intensity of an electron beam.
