  • Patent number: 6814809
    Abstract: A coating and developing apparatus has an interface section equipped with a temperature adjuster (a cooling unit). A temperature-raised substrate due to exposure on periphery of the substrate outside a circuit-forming area thereon is adjusted to a predetermined temperature by the temperature adjuster and then transferred to an exposing apparatus. The temperature adjustments before exposure provide almost the same temperature over many substrates to be transferred to the exposing apparatus for less thermal effects to exposing processing, thus achieving high yields. The interface section is further provided with first and second transfer mechanisms, the first serving to transfer substrates between the processor and the exposing apparatus and the second serving to transfer substrates to each unit of a shelf section, for high transfer performance, thus achieving high throughput.

  • Patent number: 6814839
    Abstract: A process is provided for sputter-induced precipitation of metal oxide layers on substrates by means of a reactive sputter process. The plasma charge acting upon the target to be evaporated is provided with electric power selected such that the metal oxide layers precipitated on the substrates to be coated are deposited at a precipitation rate of ≧4 nm/s. During the coating process the substrate to be coated is arranged stationary in relation to the target material to be evaporated. The electrodes are connected in a conductive manner to the outputs of an alternating current source whereby the alternating frequency of the alternating current provided for the electrical supply of the plasma discharge is selected between 10 kHz and 80 kHz. Particularly preferred is that the precipitated oxide layer is a TiO2 layer or an SiO2 layer.

  • Patent number: 6814841
    Abstract: A gas/liquid phase separator includes a fluid inlet, a vapor outlet, a liquid outlet, and first and second valves disposed in fluid communication with the liquid outlet. Both valves are controllable in response to a system pressure and a fluid level in the gas/liquid phase separator. Both valves are further disposed in parallel fluid communication with each other. A method of controlling a liquid level in the phase separator includes sensing an amount of liquid in the phase separator, sensing a system pressure, and selectively opening a valve disposed in fluid communication with the phase separator to drain the liquid.

  • Patent number: 6814845
    Abstract: Improved biosensors are provided having excellent selectivity and stability properties, together with methods of preparing the biosensors. A preferred biosensor includes an electrode (12) having enzyme (16) deposited thereon together with a layer of electropolymerized polymer (18) intermingled with the enzyme (16); a crosslinked silane film (20) is applied over the polymer layer (18), and a final coating (22) of polyurethane is formed over the film (20). In preparative procedures, the enzyme (16) is electrodeposited using an aqueous enzyme solution containing a nonionic surfactant at a concentration level preferably in excess of the critical micelle concentration of the surfactant. In the case of a glucose sensor, the polymer layer (18) is preferably polyphenol, while the silane film is crosslinked (3-aminopropyl) trimethoxysilane. The preferred biosensors have greatly enhanced selectivity stabilities.
