Abstract:
An electropolishing method for removing potential device-contaminating particles from a wafer, is disclosed. The method includes immersing the wafer in an electropolishing electrolyte solution and removing defects and particles from the wafer by rotational friction between the wafer and the electrolyte solution in combination with electrolysis. The method is effective in removing particles from via openings of all sizes, including via openings having a width smaller than about 0.2 μm.

Abstract:
An apparatus and method to assess the compressibility, density, and hematocrit of blood including an optical ultrasound probe clipped onto tubing in which blood is flowing. The probe includes a combination of ultrasound transducers, a light emitting diode, and photodiodes. An indicator medium is injected into the bloodstream of the subject over one or more time points. Ultrasound waves are emitted by a transducer and received by another transducer, and a novel signal-processing unit and a computer with a novel computation scheme process the ultrasound signals to assess the phase shift of ultrasound as it transmitted across the blood stream. Based on the linear relationship between compressibility and density, changes in blood density are calculated from changes in phase shift. The optical part of the probe assesses the hematocrit of blood. Two fluid media are used to calibrate the probe on the relationship between phase shift and density in the factory. Before clinical assessment, an on-line saline injection procedure and the resulting change in density is employed to calibrate the optical density of the optical probe in terms of hematocrit and to establish the interrelation between density and hematocrit on fluid dilution of the circulating blood. One clinical protocol to monitor blood volume and microvascular pooling employs saline infusion to determine the blood volume hourly and the density and hematocrit measurements to determine the change in blood volume and the volume pooled to the microcirculation. Another clinical protocol assesses the time course of hematocrit and density over hemodialysis treatment for the prediction of hypovolemia and microvascular pooling. This cardiovascular monitoring is useful for evaluating how complications are developed during hemodialysis or the adequacy of any post-trauma fluid replacement or therapy to alleviate the complications.
Abstract:
An apparatus and method to assess the compressibility of blood includes a combination of ultrasound transducers attached to tubing in which blood is flowing. An indicator medium is injected into the bloodstream of the subject over one or more time points and ultrasound waves are transmitted and monitored using transducers and phase lock amplifier to assess transmission time. Using a linear relationship between compressibility and density, changes in blood density are calculated from changes in transmission time to predict blood density changes and then the blood volume and microvascular pooling. This information allows prediction of complications that can occur during hemodialysis or because of post-traumatic fluid replacement and development of therapy to alleviate the complications.
Abstract:
An endoscope includes a tube having including a compartment extending in a longitudinal direction. A flexible strip has a diameter smaller than a diameter of the compartment. The flexible strip is received in the compartment and slideable relative to the tube in the longitudinal direction. The flexible strip is made of a super elastomer having an original shape before deformation. The flexible strip is capable of restoring the original shape after larger deformation. An image capturing module is mounted to the flexible strip. The image capturing module can transmit light beam and capture images.
