Apparatuses and methods for measuring a velocity component of tissue and blood flow within a human body may generate sample data by transmitting ultrasound signals to and sampling echo signals reflected from the human body, generate frequency distribution data containing the velocity component of tissue and blood flow, extract the frequency distribution data corresponding to the velocity component of tissue flow from the frequency distribution data, and display the extracted frequency distribution data. The apparatuses and methods may also input the frequency distribution data containing the velocity component of tissue and blood flow, eliminate a direct-current component of the frequency distribution data, extract the velocity component of blood flow from the frequency distribution data, determine a maximum value of the extracted velocity component of blood flow, decide a gain level, and multiply the frequency distribution data by the decided gain level.
摘要:
A method for plasma etching a semiconductor film stack. The film stack includes at least one layer comprising silicon oxynitride. The method includes etching the silicon oxynitride-comprising layer using an etchant gas mixture comprising chlorine and at least one compound containing fluorine and carbon. The atomic ratio of fluorine to chlorine in the etchant gas ranges between about 3:1 and about 0.01:1; preferably, between about 0.5:1 and about 0.01:1; most preferably, between about 0.25:1 and about 0.1:1. The etchant gas forms a fluorine-comprising polymer or species which deposits on exposed surfaces adjacent to the silicon oxynitride-comprising layer in an amount sufficient to reduce the etch rate of an adjacent material (such as a photoresist) while permitting the etching of the silicon oxynitride-comprising layer.
