    摘要: A method for fabricating a semiconductor structure comprises the steps of providing a silicon substrate (10) having a surface (12); forming on the surface of the silicon substrate an interface (14) comprising a single atomic layer of silicon, nitrogen, and a metal; and forming one or more layers of a single crystal oxide (26) on the interface. The interface comprises an atomic layer of silicon, nitrogen, and a metal in the form MSiN2, where M is a metal. In a second embodiment, the interface comprises an atomic layer of silicon, a metal, and a mixture of nitrogen and oxygen in the form MSi[N1−Ox]2, where M is a metal and X is 0≦X

    摘要: A method of forming a thin silicide layer on a silicon substrate 12 including heating the surface of the substrate to a temperature of approximately 500.degree. C. to 750.degree. C. and directing an atomic beam of silicon 18 and an atomic beam of an alkaline-earth metal 20 at the heated surface of the substrate in a molecular beam epitaxy chamber at a pressure in a range below 10.sup.-9 Torr. The silicon to alkaline-earth metal flux ratio is kept constant (e.g. Si/Ba flux ratio is kept at approximately 2:1) so as to form a thin alkaline-earth metal silicide layer (e.g. BaSi.sub.2) on the surface of the substrate. The thickness is determined by monitoring in situ the surface of the single crystal silicide layer with RHEED and terminating the atomic beam when the silicide layer is a selected submonolayer to one monolayer thick.

    摘要: High quality epitaxial layers of monocrystalline oxide materials (24) can be grown overlying monocrystalline substrates (22) such as large silicon wafers. The monocrystalline oxide layer (24) comprises a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer (28) of silicon oxide. The amorphous interface layer serves as a decoupling layer between the substrate and the buffer layer so that the substrate and the buffer is crystal-graphically, chemically, and dielectrically decoupled. In addition, high quality epitaxial accommodating buffer layers may be formed overlying vicinal substrates using a low pressure, low temperature, alkaline-earth metal-rich process.

    摘要: A method and a vending apparatus for self-checkout unpackaged products is disclosed. The vending apparatus holds goods on one or more product trays. Load cells are mounted under each product tray and can measure the weight of the goods on the product tray in real time. A user may use a credit/debit card or an online payment app to unlock the vending apparatus and to initiate a purchase. The user may take any desired amount of goods. The apparatus automatically detects the type of goods and the weight amount taken by the user and calculates the total cost. After the user payment, the apparatus automatically resets the initial weight of the goods and is ready for the next transaction. The present invention improves the vending machine technology and expands its application to offering unpackaged products.
