    Abstract: A sensor can be configured to generally include a flow channel block having a flow channel formed therein, and a sensor chip for sensing fluid flow, wherein a fluid in the flow channel surrounds the sensor chip. Alternatively, the sensor chip can be fastened at one side to a substrate and on another side of the substrate to a core tube inserted into the flow channel. This core tube provides electrical insulation and corrosion protection to the sensor chip, reduces flow noise, (and by the non-intrusive nature of the measurement) essentially eliminates the risk of fluid leakage, and maintains the fluid super-clean and contamination-free while improving structural integrity for the thermal measurements derived from the sensor chip. The use of such a core tube configuration also can protect the sensor from corrosion, radioactive or bacterial contamination, overheating, or freeze-ups.

  • Patent number: 6518872
    Abstract: A resistant based thermal probe including a nanometer sized four-leg filament integrated with a piezoresistive AFM type cantilever is created by depositing the filament structure onto the cantilever by a chemical vapor deposition technique where the cantilever is exposed to the flux of precursor gas. An incident electron beam causes a fragmentation of the gas molecules leaving a deposit behind which leads to a conductive deposit shaped as a multi-leg filament structure for thermal measurements of a sample. A deposited four leg filament structure has a mechanical rigidity, high spatial resolution, low thermal conductivity and thermal capacitance, fast response time, and in combination with a four point resistant measurement and lock-in technique, eliminates resistivity for increasing both the temperature sensitivity and the signal-to-noise ratio of the thermal probe.

    Abstract: A printed circuit board has a conductor path applied to a substrate having an electrically insulating surface, the conductor path preferably being constructed in the shape of a meander and containing connection areas with holes to which small contact plates are applied for the purpose of later bonding with connection leads. The small contact plates are applied in a hard soldering process with the aid of solder paste to the connection areas of the conductor paths and to the surface area of the substrate surface which is made of ceramic and exposed by the holes. It is consequently possible, dispensing with so-called bonding wires, to directly connect connection leads or bonding lugs electrically with the conductor path and mechanically with the printed circuit board. The printed circuit board is preferably designed as a measuring resistor, wherein the conductor path is applied as a resistance layer of platinum or platinum group metal in a thin film process to a small ceramic plate of aluminum oxide.

  • Patent number: 6437680
    Abstract: For manufacturing of sensors, especially temperature sensors, respectively two connection bridges spaced in the grid of a continuous carrier strip with contact pads for later electrical and mechanical connection with respectively one sensor element in the continuous carrier strip are at least partially injection molded around with plastic, such that on the connection bridges at least two plastic bodies arise arranged at a distance to each other. Between plastic bodies of respectively adjacent connection bridges, spacer elements made of plastic are formed in the same injection operation, while contact pads and ends of the connection bridges remain free of plastic. In connection with the injection operation, the edges of the carrier strip are separated from the connection bridges by punching.

  • Patent number: 6437681
    Abstract: The present invention discloses a temperature sensor. The temperature sensor includes an aluminum oxide substrate and a thin-film resistor having a specific temperature coefficient of resistance (TCR) disposed over the substrate. The temperature sensor further includes an aluminum oxide stress-relief layer covering the thin film resistor. The temperature sensor further includes a passivation layer covering the aluminum oxide stress-relief layer. The aluminum oxide stress-relief layer further has at least one resistor-trimming trench formed by removing a portion of the aluminum oxide stress-relief layer and thin-film resistor therefrom and the resistor-trimming trench is filled with a material of the passivation layer. In a preferred embodiment, the temperature sensor further includes a set of dummy pads for resistance-trimming measurement disconnected from the thin film resistor disposed on the substrate near the thin film resistor covered by the passivation layer.

  • Publication number: 20020109577
    Abstract: An electrical resistor has a resistance layer containing platinum or a platinum group metal, which is applied to an electrically insulating surface of a substrate, wherein the resistance layer is constructed as a thin layer element and is made of a physical mixture of finely dispersed ceramic and metal. Preferably, the ratio of finely dispersed ceramic to metal lies in a range of about 5 to 50% by weight. Preferably, the finely dispersed ceramic is selected from SiO, Sio2, Ta2O5, MgO, Al2O3, and mixtures thereof. The resistor is used as a reference resistor in a sensor (temperature sensor) together with a temperature-dependent measuring resistor, wherein both resistors are arranged on a common substrate.

  • Publication number: 20020084885
    Abstract: A method for producing a platinum-containing resistor, configured as a temperature sensor, includes applying a resistive coat to a ceramic support having a surface of electrically insulating material, covering an outer surface of the resistive coat with at least one layer of an electrically insulating material, which is preferably applied as a diffusion barrier in the form of an intermediate layer, and forming an electrode on the side of the resistive coat facing away from the substrate surface and spaced therefrom, using a thick-film technique. This electrode, comprising a layer of platinum, is covered by a glass passivation layer and is therefore surrounded by the electrically insulating material of the diffusion barrier and the glass passivation layer. The electrode is negatively electrically biased in relation to at least one connection of the resistive layer or the measuring resistor.
