Abstract: An adjustable polarity laser device may treat cancer and other conditions that are responsive to polarized laser energy. The device provides both low-level laser and electrical stimulation of a treatment area, such as a tumor to promote the body's natural defense systems against harmful cells in the treatment area. The device produces low-level laser beams that are polarized with either birefringent or electrically conductive materials disposed in the path of the laser beams. Electrically conductive polarizers are charged by an electric current to impart polarity on the passing laser beams. Treatment methods include applying polarized laser energy to the targeted treatment area. The polarization of each laser beam may be selected and alternated as necessary for the condition being treated. Additionally, photodynamic compounds or photosensitizing agents can be administered to the patient prior to applying polarized laser energy.

A stripper bar is connected to the brush hood and is movable with the hood surface when the hood surface moves between its down and up positions. At least one actuator is operably connected between the brush frame and the brush hood and is selectively operable to move the hood surface between its up and down positions.

Abstract: A trench capacitor structure in which arsenic contamination is substantially reduced and/or essentially eliminated from diffusing into a semiconductor substrate along sidewalls of a trench opening having a high aspect ratio is provided. The present invention also provides a method of fabricating such a trench capacitor structure as well as a method for detecting the arsenic contamination during the drive-in annealing step. The detection of arsenic for product running through the manufacturing lines uses the effect of arsenic enhanced oxidation. That is, the high temperature oxidation anneal used to drive arsenic into the semiconductor substrate is monitored for thickness. For large levels of arsenic outdiffusion, the oxidation rate will increase resulting in a thicker oxide layer. If such an event is detected, the product that has been through the process steps to form the buried plate up to the drive-in anneal, can be reworked to reduce arsenic contamination.
