    摘要: Within a local oxidation of silicon (LOCOS) method for forming a silicon oxide isolation region, there is first amorphized areally completely at least a surface sub-layer portion of a silicon layer within an isolation region location within the silicon layer defined by an oxidation mask layer formed over the silicon layer, to form an amorphized silicon region within the isolation region location. Thus, when thermally oxidizing the silicon layer having formed thereover the oxidation mask layer to form at least in part from the amorphized silicon region a silicon oxide isolation region, the silicon oxide isolation region is formed with an attenuated bird's beak extension.

    摘要: A measuring system and method of detecting an object distance by transmission media with different wave velocities are described. The measuring system has a computer, a primary detector and a secondary detector.

The primary detector is able to receive separately a first signal and a second signal emitted simultaneously from the secondary detector through the transmission media. Moreover, the first signal has light-speed and the second signal has sound-speed. To calculate the distance between the objects which the primary and the secondary detector are attached respectively. The delay time of second signal and the wave velocity of the supersonic media are multiplied.

    摘要: A high voltage transformer for controlling inductance leakage used for a multiple lamp driving system includes at least one wire frame, a first winding, a second winding, a first magnetic unit, and a second magnetic unit. There is a receiving space in the wire frame for receiving the first magnetic unit, and a first region and a second region is formed on its surface. The first winding and the second winding are individually wound at the first region and the second region. The second magnetic unit is covered on the side of the wire frame. On an appropriate location of the bottom of the second magnetic unit, a transverse beam extends. Thereby, the transverse beam fully separates the low voltage magnetic flux path produced on the first magnetic unit by the first winding and the second winding and the high voltage magnetic flux path produced by the AC.
