Method for anisotropic plasma-chemical dry etching of silicon nitride layers using a gas mixture containing fluorine

An etching gas mixture containing CHF3, SF6 and a non-oxidizing gas such as Ar is used as an etching gas mixture for the anisotropic plasma-chemical dry-etching of a silicon nitride layer differentially or selectively relative to a silicon oxide layer. The gas mixture does not contain oxygen, chlorine, bromine, iodine or halides in addition to the above mentioned constituents, so that the process can be carried out in reactor systems equipped with oxidizable electrodes. By adjusting the gas flow rates or composition ratios of CHF3, SF6, and argon in the etching gas mixture, it is possible to adjust the resulting etching selectivity of silicon nitride relative to silicon oxide, and the particular edge slope angle of the etched edge of the remaining silicon nitride layer. A high etch rate for the silicon nitride is simultaneously achieved.

Automatic Blade Control System with Integrated Global Navigation Satellite System and Inertial Sensors

Disclosed are method and apparatus for controlling the blade elevation and blade slope angle of a dozer blade. Elevation and slope angle measurements are calculated from measurements received from a global navigation satellite system (GNSS) antenna and an inertial measurement unit mounted on the dozer blade. The inertial measurement unit includes three orthogonally placed accelerometers and three orthogonally placed rate gyros. The measurements are processed by algorithms to calculate estimates of the blade elevation, blade vertical velocity, blade slope angle, and blade slope angular velocity. These estimates are then provided as inputs to a control algorithm which provides control signals to control a dozer hydraulic system which controls the blade elevation and blade slope angle.

Irradiance-redistribution lens and its applications to LED downlights

An illumination-redistribution lens comprising a thick aspheric lens collecting a high proportion of the luminous output of a compact LED with a quasi-hemispheric pattern. After receiving the highly nonuniform illuminance from the nearby LED, the lower surface refractively deflects these rays into a less diverging angular pattern that results in uniform illuminance on the upper surface of the lens, which itself is shaped so its distribution of slope angles refractively deflects the uniform illuminance distribution into an exiting beam that will produce uniform illuminance on a distant target, such as a table below a ceiling-mounted unit. When square-cut sections of such lenses are laterally arrayed to form a downlight, a uniform rectangular spot will be produced on the target.

Automatic Blade Slope Control System

The slope angle of a blade on an earthmoving machine is automatically controlled based on measurements from a three-axis gyroscope, a blade slope angle tilt sensor, and a blade tip angle tilt sensor mounted on the blade. A three-axis gyroscope has high dynamic response and high resistance to mechanical disturbances but is subject to potentially unbounded errors. A tilt sensor has bounded errors but has a slow dynamic response and a high sensitivity to mechanical disturbances. The combination of a three-axis gyroscope and two tilt sensors provides an advantageous measurement system. Algorithms for performing proper fusion of the measurements account for the lack of synchronization between the three-axis gyroscope and the tilt sensors and also screen out invalid measurements from the tilt sensors. The blade slope angle is controlled based on a reference blade slope angle and an estimate of the blade slope angle computed from properly fused measurements.
