Abstract: A semiconductor wafer having no photoresist craters at the completion of a two-step post-apply resist bake (soft bake) in the fabrication of an integrated circuit. A process and method for soft baking the semiconductor wafer so that photoresist layers are free of surface voids or craters. The semiconductor wafer is coated with resist and then baked at both a low-bake temperature and a high-bake temperature. It is theorized that the lower temperature bake either hardens the resist layer before trapped air expands through the resist or displaces the trapped air while the resist layer remains fluid and returns to its conformal shape.

Abstract: One or more techniques are provided for measuring the motion of an organ in three dimensions. As provided by the technique, the motion of the organ along each dimension may be determined by a suitable methodology. Where sensor-based motion measurements are suitable, one or more sensors may be placed on a patient to measure internal motion of the organ of interest along one or more perpendicular axes. Where image-based techniques are suitable, the motion of the internal organ along a perpendicular axis may determined using pre-acquisition image data or acquisition image data when suitable. Concurrent motion vectors for all three dimensions may be obtained from the motion data acquired for the perpendicular axes by the disparate methodologies. The concurrent motion vectors may be combined to describe the three-dimensional motion of the organ over time.

Abstract: A low emissions 2-stroke natural gas fueled engine includes at least one cylinder with an exhaust port in communication with a silencer/catalytic converter unit. The unit has first and second volumes in communication with each other. The first volume dampens spurious exhaust pressure excursions and removes particulates in the exhaust.

The first volume preferably has a pressure relief valve set to relieve at a pressure greater than the maximum normal operating pressure of the engine to avoid excessive pressure excursions of the engine exhaust from damaging the oxidation catalyst.
