摘要： A method for forming insulator filled, shallow trench isolation regions, with rounded corners, has been developed. The process features the use of a polymer coated opening, in an insulator layer, used as a mask to define the shallow trench region in silicon. After completion of the shallow trench formation the polymer spacers are removed, exposing a region of unetched semiconductor, that had been protected by the polymer spacers, during the shallow trench dry etching procedure. The sharp corner, at the intersection between the shallow trench and the unetched region of semiconductor, is then converted to a rounded corner, via thermal oxidation of exposed silicon surfaces. The polymer spacers also eliminate the top corner wraparound.

摘要： This invention describes methods to compute coronary physiology indexes using a high precision registration model, which consists of acquiring coronary angiography images of coronary vessels, performing intravascular imaging, and registering the coronary angiography images with intravascular images to create a high precision registration model, based upon which the coronary flow, fractional flow reserve (FFR) and index of microcirculation resistance (IMR) can be computed. The methods described in this invention to compute coronary flow, FFR, IMR are based on both coronary angiography and intravascular images, and the accuracy is better than those derived from coronary angiography alone or intravascular imaging alone, and have high practical values.
