APPARATUS AND METHOD FOR REAL-TIME SENSING OF PROPERTIES IN INDUSTRIAL MANUFACTURING EQUIPMENT
An apparatus and method for real-time sensing of properties in industrial manufacturing equipment are described. The sensing system includes first plural sensors mounted within a processing environment of a semiconductor device manufacturing system, wherein each sensor is assigned to a different region to monitor a physical or chemical property of the assigned region of the manufacturing system, and a reader system having componentry configured to simultaneously and wirelessly interrogate the plural sensors. The reader system uses a single high frequency interrogation sequence that includes (1) transmitting a first request pulse signal to the first plural sensors, the first request pulse signal being associated with a first frequency band, and (2) receiving uniquely identifiable response signals from the first plural sensors that provide real-time monitoring of variations in the physical or chemical property at each assigned region of the system.
Bus Bar
In an embodiment a bus bar includes a first interface and a second interface, a filter element electrically connected between the first and the second interface and a first rail between the first interface and the second interface, wherein the first rail includes a central section with a metal sheet and a dielectric material at least partially covering the central section.
Discrete cofired feedthrough filter for medical implanted devices
Discrete cofired feedthrough filters are provided for medical implanted device applications. A plurality of discrete vertical feedthrough filter elements are respectively associated with a plurality of signal wires or pins otherwise supported by an insulating feedthrough and a ferrule. The resulting discrete device comprises a single-element device which is cheaper to make, and which reduces cross-talk between adjacent signal wires/pins while otherwise accommodating changes in feedthrough pitch without having to redesign the filter.
TECHNOLOGIES FOR LOW-LEAKAGE ON-CHIP CAPACITORS
Technologies for low-leakage and low series resistance on-chip capacitors are disclosed. In the illustrative embodiment, each electrode of a capacitor is formed from two metal layers and vias between the metal layers. A high-k dielectric layer is between the metal layers. The electrodes are displaced relative to each other on the plane defined by the high-k dielectric layer. As a result, electric field lines of the capacitor are parallel to the high-k dielectric layer. The electrodes can be displaced from each other by more than the thickness of the high-k dielectric layer, reducing the leakage current through the high-k dielectric layer as compared to a capacitor with field lines perpendicular to the high-k dielectric layer. Such a capacitor may be used to provide power to circuits in a low-power state with little leakage current and/or may be used to absorb radiofrequency (RF) interference.
FILTER DEVICE AND POWER CONVERSION DEVICE
Provided is a filter device including a π-type noise filter, and a metal case in which a first ground point and a second ground point are formed. The π-type noise filter includes a magnetic core configured to surround a direct current wiring, a first capacitor disposed in a stage preceding the magnetic core, a second capacitor disposed in a stage subsequent to the magnetic core, each of the first capacitor and the second capacitor connected to a corresponding one of the first ground point and the second ground point. A first partition and a second partition opposing each other are formed between the first ground point and the second ground point, and the first partition and the second partition have a predetermined gap between each other. Provided is a power conversion device including the filter device and a power conversion unit.

Filter circuit for preventing reverse inflow of electromagnetic waves
According to the present disclosure, a filter for reducing electromagnetic noise discharged through a line connected to the positive terminal B(+) of the battery is designed, but there is a problem that noise is rather introduced through this filter. However, in the filter circuit of the present disclosure, noise reversely introduced through the filter may be blocked by arranging an inductor for the filter in an expected inflow path of noise.
