20150020607 | MAGNETIC FLOWMETER - A magnetic flowmeter for measuring flow rate of a process fluid includes: a magnetic coil arranged to apply a magnetic field to the process fluid. A pair of electrodes electrically couple to the process fluid and are arranged to sense a voltage induced in the process fluid related to the applied magnetic field and the flow rate of the process fluid. A flow tube of a non-conductive material is arranged to receive a flow of the process fluid therethrough. The flow tube carries the magnetic coil and the pair of electrodes. Flow meter circuitry applies a current to the magnetic coil and receives the voltage sensed by the pair of electrodes. A magnetic field spreader is positioned proximate the magnetic coil and is arranged to spread the magnetic field emanating from the magnetic coil and direct the magnetic field into the flow tube. An exterior wrapper extends around the assembly and completes a magnetic circuit. | 01-22-2015 |

20150179497 | ISOLATION STRUCTURE AND MANUFACTURING METHOD THEREOF FOR HIGH-VOLTAGE DEVICE IN A HIGH-VOLTAGE BCD PROCESS - The invention provides an isolation structure and a manufacturing method thereof for a high-voltage device in a high-voltage BCD process, the isolation structure comprising: a semiconductor substrate having a first type of doping; an epitaxial layer having a second type of doping over the semiconductor substrate, wherein the first type of doping is opposite to the second type of doping; an isolation region having the first type of doping, wherein the isolation region extends through the epitaxial layer into the semiconductor substrate, and wherein the isolation region has a doping concentration on the same order as a doping concentration of the epitaxial layer; a field oxide layer over the isolation region. This invention effectively isolates the epitaxial island where the BCD high-voltage device is located, thereby increasing the breakdown voltage of the high-voltage device in the BCD process. Further, with a minimum thickness of the field oxide layer, the parasitical threshold voltage between the aluminum wiring and the silicon surface of the high-voltage device can be higher than 1200V, thereby improving the planarization of oxide layer steps on the silicon surface in the whole high-voltage BCD process, and enhancing the reliability of the product. | 06-25-2015 |
