    摘要: High quality epitaxial layers of compound semiconductor materials can be grown overlying large silicon wafers by first growing an accommodating buffer layer on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline compound semiconductor layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. To further relieve strain in the accommodating buffer layer, at least a portion of the accommodating buffer layer is exposed to a laser anneal process to cause the accommodating buffer layer to become amorphous, providing a true compliant substrate for subsequent layer growth.

    摘要: High quality epitaxial layers of monocrystalline materials can be grown overlying monocrystalline substrates such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. One way to achieve the formation of a compliant substrate includes first growing an accommodating buffer layer (204) on a silicon wafer (202). The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer (206) of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. In addition, formation of a compliant substrate may include utilizing surfactant enhanced epitaxy, epitaxial growth of single crystal silicon onto single crystal oxide, and epitaxial growth of Zintl phase materials. Quantum well infrared photodetectors (200) can be grown on the high quality epitaxial monocrystalline material formed on such compliant substrates to create highly reliable devices having reduced costs.

    摘要: A transistor (12) and method of making an integrated circuit (10) uses a chromium based sacrificial gate (22A) to align, dope and activate source and drain portions (36, 38, 52, 53,) of the transistor. The transistor is subjected to a high temperature to activate the source and drain, which would damage a high permittivity gate dielectric. The sacrificial gate is removed by etching with ceric ammonia nitrate. A high permittivity gate dielectric (72) and a final gate electrode (74) are formed over a channel (30) of the transistor. Electrodes (76, 78) are formed for coupling to the source and drain.
