  • Patent number: 6715689
    Abstract: An intelligent air-condition system that detects the signals of the temperature distribution among the environment by using the infrared radiation, especially detects the location of the human-body temperature signals. Hence, according to the detected signals, the gas(es) for air-conditions can be firstly transmitted into the location where the human-body temperature signals exist, or be firstly transmitted into where the local temperature is urgent to be adjusted. Besides, the transitions of the gas(es) can be paused or stopped while there is no human-body temperature.

  • Patent number: 6359294
    Abstract: An insulator-compound semiconductor interface structure is disclosed including compound semiconductor material with a spacer layer of semiconductor material having a bandgap which is wider than the bandgap of the compound semiconductor material positioned on a surface of the compound semiconductor material and an insulating layer positioned on the spacer layer. Minimum and maximum thicknesses of the spacer layer are determined by the penetration of the carrier wave function into the spacer layer and by the desired device performance. In a specific embodiment, the interface structure is formed in a multi-wafer epitaxial production system including a transfer and load module with a III-V growth chamber attached and an insulator chamber attached.

  • Patent number: 6159834
    Abstract: A gate quality oxide-compound semiconductor structure (10) is formed by the steps of providing a III-V compound semiconductor wafer structure (13) with an atomically ordered and chemically clean semiconductor surface in an ultra high vacuum (UHV) system (20), directing a molecular beam (26) of gallium oxide onto the surface of the wafer structure to initiate the oxide deposition, and providing a second beam (28) of atomic oxygen to form a Ga.sub.2 O.sub.3 layer (14) with low defect density on the surface of the wafer structure. The second beam of atomic oxygen is supplied upon completion of the first 1-2 monolayers of Ga.sub.2 O.sub.3. The molecular beam of gallium oxide is provided by thermal evaporation from a crystalline Ga.sub.2 O.sub.3 or gallate source, and the atomic beam of oxygen is provided by either RF or microwave plasma discharge, thermal dissociation, or a neutral electron stimulated desorption atom source.

  • Patent number: 6113690
    Abstract: A method of preparing crystalline alkaline earth metal oxides on a Si substrate wherein a Si substrate with amorphous silicon dioxide on a surface is provided. The substrate is heated to a temperature in a range of 700.degree. C. to 800.degree. C. and exposed to a beam of alkaline earth metal(s) in a molecular beam epitaxy chamber at a pressure within approximately a 10.sup.-9 -10.sup.-10 Torr range. During the molecular beam epitaxy the surface is monitored by RHEED technique to determine a conversion of the amorphous silicon dioxide to a crystalline alkaline earth metal oxide. Once the alkaline earth metal oxide is formed, additional layers of material, e.g. additional thickness of an alkaline earth metal oxide, single crystal ferroelectrics or high dielectric constant oxides on silicon for non-volatile and high density memory device applications.

  • Patent number: 6110840
    Abstract: A method of passivating the surface of a Si wafer is disclosed including the steps of cleaning the surface of the Si wafer and depositing an alkaline earth metal on the clean surface at a wafer temperature in a range of approximately 400.degree. C. to 750.degree. C. The surface is monitored during deposition to detect a (4.times.2) surface reconstruction pattern indicating approximately a one-quarter monolayer of alkaline earth metal is formed. The wafer is annealed at a temperature in a range of 800.degree. C. to 900.degree. C. until the alkaline earth metal forms an alkaline earth metal silicide with a (2.times.1) surface pattern on the surface.

  • Patent number: 6094295
    Abstract: An electro-conductive ultraviolet light transmitting Ga.sub.2 O.sub.3 material (10) with a metallic oxide phase is deposited on a GaAs substrate or supporting structure (12). The Ga.sub.2 O.sub.3 material or thin layer comprises a minor component of metallic IrO.sub.2.
