  • Patent number: 6965128
    Abstract: High quality epitaxial layers of monocrystalline materials (26) can be grown overlying monocrystalline substrates (22) such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer (24) comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer (28) of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer 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 and epitaxial growth of single crystal silicon onto single crystal oxide materials. A microresonator device is formed overlying the monocrystalline substrate.

  • Publication number: 20030036217
    Abstract: 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 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 foregoing is utilized for a microcavity semiconductor laser coupled to a waveguide.

  • Patent number: 6048699
    Abstract: A method of fabricating one or more arrays of bio-molecule test sites including providing a solution containing bio-molecule probes in contact with the surface of a substrate, using orthogonal acoustic waves to concentrate the bio-molecule probes at a node intersection, bonding the bio-molecule probes on the substrate at the node intersection to form a test site, and removing the solution leaving the bio-molecule probes attached to the surface at the test site. The steps are repeated as often as desired, using different bio-molecule probes, to produce one or more arrays of test sites.

  • Patent number: 5801800
    Abstract: A visual display system, composed of an array of light emitting devices, forming an image source, a phase spatial light modulator scanner, driver/control circuitry and an optical magnification system. The display system being enclosed within a housing, thereby forming an optical magnifier. The phase spatial light modulator scanner is operative in either a transmissive mode or a reflective mode. In operation, an external stimulus, such as a voltage, is applied to the scanner, thereby changing the phase of light emitted therethrough. The scanning action enhances display resolution of the generated resultant image without an increase in the number of pixels of the image source. The phase spatial light modulator scanner operates by scanning sub-pixels, pixel groups, and/or sub-arrays of the image source.
