Claim 10:
11. The method of claim 10, wherein the forming of the second semiconductor layer includes:
forming the first region of the second semiconductor layer from a first precursor and a second precursor, the first precursor and the second precursor dosed at a first flow rate ratio,
forming the second region of the second semiconductor layer from the first precursor and the second precursor, the first precursor and the second precursor dosed at a second flow rate ratio, and
forming the third region of the second semiconductor layer from the first precursor and the second precursor, the first precursor and the second precursor dosed at a third flow rate ratio,
wherein the first flow rate ratio is substantially the same as the third flow rate ratio, and the first flow rate ratio is different from the second flow rate ratio.
