Abstract: Measurements of line roughness are separated into groups depending upon pre-layers. Image data collected from similar pre-layer types are considered together in order to separate effects of line roughness from distortion of measurements caused by the pre-layers. The resulting line roughness measurements are used to estimate an aspect of line quality.

Abstract: A light emitting device includes a carrier, a light emitting element disposed and electrically connected to the carrier, and a transparent plate disposed on the carrier and including a flat-portion and a lens-portion. The lens-portion covers the light emitting element and has a light incident surface, a light emitting surface, a first side surface and a second side surface. The light emitting element is suitable for emitting a light beam. A first partial beam of the light beam passes through the light incident surface and leaves from the light emitting surface. A second partial beam of the light beam passes through the light incident surface and is transmitted to the first side surface or the second side surface, and the first side surface or the second side surface reflects at least a part of the second partial beam of the light beam to be passed through the light emitting surface.

Abstract: A structure of a semiconductor device including a substrate and a patterned layer is provided. The patterned layer being patterned to have an open area and a dense area is disposed on the substrate. The patterned layer includes, in the dense area, a first pattern adjacent to the open area and a second pattern. The first pattern has a first bottom. The second pattern has a second bottom width. The bottom of the first pattern includes a recess facing the open area, so that the first bottom width is close to the second bottom width.

Abstract: An angle-adjusting device for the wind-resisting plates of the resisting wheel of a stationary bike includes an adjusting button for actuating a pushing unit on the shaft of a resisting wheel to rotate. A coupled rotary sleeve fitted in the pushing unit and restricted to shift axially has its inner wall fixed with an offset-angled projecting member. A main gear unit fitted on the shaft by a bearing has a sleeve having one end inserted in the coupled rotary sleeve and bored with an oblique recess for the offset-angled projecting member to engage with and a main bevel gear having its toothed side facing the resisting wheel. The wind-resisting plates have their shafts respectively provided with an auxiliary bevel gear engaged with the main bevel gear. The angles of the wind-resisting plates can be adjusted by pulling the adjusting button.
