    摘要: A method comprises, in a reaction chamber, depositing a seed layer of germanium over a silicon-containing surface at a first temperature. The seed layer has a thickness between about one monolayer and about 1000 Å. The method further comprises, after depositing the seed layer, increasing the temperature of the reaction chamber while continuing to deposit germanium. The method further comprises holding the reaction chamber in a second temperature range while continuing to deposit germanium. The second temperature range is greater than the first temperature.

    摘要: Dual channel heterostructures comprising strained Si and strained Ge-containing layers are disclosed, along with methods for producing such structures. In preferred embodiments, a strain-relaxed buffer layer is deposited on a carrier substrate, a strained Si layer is deposited over the strain-relaxed buffer layer and a strained Ge-containing layer is deposited over the strained Si layer. The structure can be transferred to a host substrate to produce the strained Si layer over the strained Ge-containing layer. By depositing the Si layer first, the process avoids Ge agglomeration problems.
